Shane Yaw I disagree. Those were very intuitive. Lagrange error bound, on the other hand... have no idea what’s going on in calc 3 rn tho

[@herbcruz4697]

The Disk/Washer Method and the Method of Cylindrical Shells are only difficult when the axis of revolution is not the x-axis or the y-axis (i.e., when it is a different line, such as x=-2, y=5, etc.).

[@jacobharris5894]

That was the hardest thing about calc 2 for me. I was horrible at the setting up the integrals until I took the time to practice it more over the summer. If it wasn’t for that I would have gotten an A in the class. Everything else for me wasn’t too bad, which is why I think ultimately calc 3 is harder.

[@AndrewSmith-eo9pv]

My university actually taught the disk/shell/washer method in calc 1 and I found it pretty easy to grasp. Personally, I found the integration techniques the hardest part of calc two. Infinite series were more straightforward and the tests for convergence/divergence were never too difficult as long as you could remember all the tests. But for some reason, integration by partial fractions and trig subs absolutely kicked my ass.

For me personally calculus 2 was my favourite. I loved doing them and they were easy marks for me. Calculus 3 however was the one where I got absolutely destroyed

[@stephencasper87]

I too loved calculus II. Still one of my favorite college classes. Having a great professor made a huge difference, I believe. Not sure I would've loved it as much had my professor sucked.

[@stephencasper87]

For me, calculus I was the hardest since it was a change in my way of thinking about math. Calculus II was my favorite math class and was the class that made me change my minor to math (I'm a Geology major). For some reason I found the sections over infinite series to be very intuitive for me. I was always "bad at math" and had a great deal of anxiety over taking any calculus class. I fortunately had some great professors and discovered I wasn't actually bad a math, I just had not found the right way to study for it. I do find the hardest part about calculus isn't the actual calculus, but the rather messy algebra that can come along with it all. If you see this comment and are about to begin a calculus class, here's some advice... Practice and understand how equations relate to their graphical illustrations and really know how to factor polynomials. Get the basics down and do not underestimate how much your algebra skills will help in subsequent classes. If you have to take Calculus III, pay close attention to vectors and really learn your unit circle (this really applies to all calculus classes).

[@appleman4996]

As someone who aced calc 1, took calc 2 4 times, and aced calc 3 I’d say calc 2 is the hardest because of how many concepts are in it that have nothing to do with each other. As you said disk and shell is just something brand new not been done before. My favorite part about math is how concepts build on each other to become more and more advanced.

[@mattdathew2794]

i found calc 2 to have topics related to each other & little concepts. Calc 2 is 80% integration, how can you say they that they have nothing to do with each other. The integrations themselves have no new concepts as integration & derivatives are calc 1 concepts & partial fractions are precalc or algebra 2 concepts. The only new concepts are volumetric integrations & series tests. on the other hand calc 3 concepts have nothing to do with each other, lines intersecting planes have nothing to do with dot products or cross products which have nothing to do with jacobians or gradients or stoke thm which have nothing to do with cylindrical or polar cordinates

[@faceless2302]

​@@mattdathew2794 I agree with him, calc 2 seemed like a jumbled mess of ideas. Integrals on their own are a lot to take in, they were just barely glanced over in the final week or two of calc 1 for me. A couple weeks into integrals and trig identities and all that and it's basically all out the window moving onto stuff like Trapezoidal and Simpson's Rules that get mentioned in a single lesson or two maybe and immediately forgotten about until they show up on your midterm. Then you're onto sequences and finding general terms which break my sad little primate brain because I can see the patterns at play but have little success trying to express it as anything that would be worth points in a gradebook. Just on the off chance you're not good at sequences, series come out nowhere to further destroy your grades and bring what feels like 50 different tests for evaluating them that you've never heard of before and that don't always work or yield any useful information at best, and actively mislead you and give the wrong answer at worst. Assuming ratio tests and whatever haven't destroyed your grade and you are still enrolled in the course, you get to move onto Taylor and Maclaurin series that feel like their own unique beasts and will definitely be on the final. Finally, having survived all that, you can move onto material that actually resembles stuff you've seen before with arc lengths and surface areas and parametrization, which, if you're lucky, may be worth like 6% of points on the final. Calc 2 is hell and it never got better in the 3 times I took it. I don't have high hopes for calc 3, but I know at least it isn't calc 2.

[@mattdathew2794]

@@faceless2302 I can see why you found it hard, I think different schools teach maths in their own unique ways. Our calc 1 final weeks were also integrals but we spent more time on them as some were definite then later we started indefinite. By the end of calc 1 we cold integrate all small expressions properly, the 2 weeks your school gives are probably not enough. We also did simpson's rule but in calc 1 not 2 Our teacher used graphics to explain how Trapezoids & cylinders of calc 2 are integrated, he was making them I think with wolfram alpha, before that I was lost. We also had arc lengths and surface areas and parametrization in precalc & may be more parametization in calc 3, but none in 2 or 1. We also had weekly quizzes & they would give us solutions afterwards for revisions as well as 3 midterms. So I think different schools do it differently, we were lucky but it was still very procedure intense, I could easily work on one integral for a full page or a half more on an exam.

Calc III is definitely the hardest, no question about that. Thinking about multivariable functions, parametrization, constrained optimization, setting up double/triple integrals, all the vector Calc theorems... no doubt Calc III is the hardest. But I can see why people say Calc II is the hardest. In Calc I, you are given specific algorithms that never deviate (product rule, chain rule...) and you think about everything in 2 dimensions. When you get to Calc II though, there is no obvious way to evaluate an integral so you have to try U-sub, then parts, then trig, then hyperbolic or weirstrass... it’s just a lot more steps. Plus, I agree, the washer and disk methods are hard to wrap your head around the and infinite series is a struggle also.

[@MikeDunn]

Amazing that some high schools actually offer Calc BC, which covers Calc 1 and 2 if I'm not mistaken.

[@FirstNameLastName-oz5ij]

I think one of the biggest reasons why calc 3 feels harder for me is the fact that in my calc 2 class, a lot of people just like me were bad at math, and it wasn’t too hard to get average or above average on tests, and since the tests were curved, as long as you are average or above, you’re fine. Once you take a calculus class above calc 2 however, almost everyone in your class is a math wiz. I think I am one of only around 3 people in my class who are barely passing calc 3 at the moment.

[@satrickptar6265]

Lucky you, the math department never curved because it's "frowned upon". They call it the weeding process of engineering.

[@OleJoe]

I would agree that calculus II is difficult, but I had a harder time with calculus III. The tripple integrals and the div, curl, grad stuff, along with Stroke's Theorem were pretty bad. Cylindrical and spherical coordinates along with surface and volume integrals... Let's not forget the Jacobian determinant for change of coordinates.

[@letsdomath1750]

Series were hard in calculus 2 because they came toward the end of my fall freshman semester, not because the math itself was inherently hard, and it was just a lot to keep in mind with all of the other science classes. Once they came up again in differential equations, they weren't that bad, and in complex analysis, they finally made complete sense as I had more experience writing proofs and doing page-long calculations with inequalities.

[@JoniniTheChickenNugget]

I agree, I had to allocate so much more time into understanding calc 2 and the taylor/mclaurin series absolutely destroyed me when I neglected memorizing the formulas.

[@uncurledink1952]

What I’ve found is that Calculus theories/methods are easy to understand after a little studying. But it’s the algebra concepts (we never thought we’d have to use again) being slightly off that screws the whole problem. It really puts your cumulative math knowledge to the test. It can be exhausting spending 20 minutes or more on a question and then finding out it was a simple algebra error holding you back. Or a simple calculus concept forgotten for a double whammy. These are the reasons why doing lots of practice problems are important but take so much time and will power to finish.

[@jc8198]

Tbh my I’ve had the same calc teacher for 11th and 12th grade and she’s phenomenal. I’ve had no problem with any topic because of her (aside from just conceptually understanding optimization) and how she makes everything so simple; She’s so good that I actually enjoyed the disk and washer method a lot. I managed to get a 5 on the ab exam and I hope to get the same for bc. I haven’t taken calc 3 but it looks daunting.

My favorite part was Stoke's and Green's theorems.

[@enerjiCS]

i havent taken calculus 3, but i made an average grade of 80-something in calc 1 and am currently sitting at an average grade of 99.3 in calc 2 two weeks before the final. the concepts are way harder in calc 2, but the difference is that in calc 2 you’re coming from calc 1 so you already have a decent foundation of calculus and how the basic concepts work. in calc 1 the concepts are so vastly different than what you learned in algebra that if you are like me you’re going to struggle initially, especially if your trig knowledge is shaky. so if you didnt do too well in calc 1 like i did and are worried about calc 2 because everyone says it is harder, dont worry, the only things you really need to have down like a pro are integration/differentiation and trig.

[@anthonysaguin7347]

Okay, quick background -I never took calc in high school, never saw it once, NEVER EVER. I had to start my (college) academic career in elementary algebra and go through a few classes before I could get into Calc 1. I am currently taking Calc 2 in what is probably the worst time to learn something (All online because covid). Here are my thoughts... Calc 1 Hard if you're disorganized (like I was). This class forced me to write neatly. This class got me to start doing my homework. This class had me changing my life habits on the real hahaha. That being said it still felt doable. Sure it felt like a lot of work sometimes but you could see the light at the end of the tunnel. Just take your time and show every step. This class taught me patience. This class also had me dyslexic for some weeks when we started learning about antiderivatives lol. Calc 2 This is the class where you can just see a problem and literally feel your world slipping away from you lol. In this class you turn the page and go, "...seriously?.." This the class that make you start staring at walls on your days off. A reason? (Hint: starts with trig). Calc 2 be like: hope you remember everything. Ok I'm tired, gn

[@bryanmartinez2515]

On next semester I passed the course with a really good one who taught us to do really amazing problems. I passed also Calculus III (several variables) but with low score; I've actually never learned Stokes/Green theorems and their properties, also I almost didn't learn surface integrals.

I did disk/shell in calculus 1 for some reason. It was pretty straightforward conceptually for me. Just a lot of work and places you can mess up.

[@Mystic0Dreamer]

My natural talent is with spatial relations and 3-D geometry, so the disk and shell methods were candy to my eyes. I also didn't have a problem setting up word problems and that's probably because I actually majored in physics. I did have a lot of problems with the infinite series, but I think part of the reason for that is that I simply wasn't interested in them and basically saw them as a waste of time when I was studying them in college. I might view them differently today. I just didn't see a practical use for them at the time. I wasn't studying as a pure mathematician. I was studying as a physicist, so if I didn't see a real-world application i found it difficult to get interested in what I viewed as having little practical value. The disk and shell methods were obviously quite practical and useful both in concrete applications, and also in an abstract geometric sense.

The Fundamental Theorem of Calculus will be the hardest thing to gasp. Using the Mean Value Theorem to prove it was very clever. It will be a challenge to new students becuase it requires a new way of thinking. I've not seen a good proof of the second derivative test of Calc3 on KZbin.

[@xyzct]

When I went to Berkeley there were three levels of complex analysis offered: 1) For -sissies- engineers; 2) For math majors; 3) For honors math majors. I took #3 and got absolutely blown to smithereens. Calculus seems like a walk in the park.

[@dw5chaosfan]

Convergence tests for series are ok, computing what the series actually converges to is another thing, and thats usually a pain in the butt. If you're proving vector identities for calc 3 then its potentially more tedious than calc 2, its hard to tell when your brain or your hand gets tired first. Complaining about the amount of indices will probably get the instructor to think less of your ability to keep up, especially if they're a geometer or analyst.

[@Kuma40]

Calc 2. Felt more like tipping point and climax. 1 Introduces integrals at the very end of semester, and limits, derivatives, and differentiation applications are glimpse in Calc 1 to give students enough time to review basic algebra and trigonometry to make sure to hone. Calc 3 is like downhill of the climax with a bit more new concept intros though you cannot deny that 1 & 2 adds 3.

[@ingGS]

I loved Calculus I and II, I got a perfect score on them also. Calculus III was tough, the toughest for me. I then took Differential Equations and it was the best of the entire series :).

[@robertjr8205]

I didn’t have a tough time with calculus 2 because I decided to devote so much time to hw and asking questions. Passed with an A after getting a C in calculus 1. The shell methods were only easy for me to visualize because I took a solidworks course that helped me see how the functions would look when revolving around a certain axis. That part helped me out a lot. Currently going over calculus 3 before my class starts and it alresdy seems complicated. I just get so easily lost with vectors and unit vectors and magnitude and i am still confused how unit vectors correlate to direction of the vector. Calculus 1 was tough for me. It was a whole new world and I couldn’t grasp the concepts fast enough or understand what my professor was trying to explain when discussing the concepts behind them. The exams were more on the comprehensive side which threw me off. I got better going into calculus 2 since I applied myself and read a little bit of the text book to get a better understanding.

I'm also not great at allocating time to studying which is a bad habit, but I think the fact that all these topics are somewhat disconnected makes it a little more difficult to remember what you've learned so far.

You got a bunch of triple integrals mixed with spherical & cylindrical coordinates, your answers are always some weird characters & expressions. There is nothing compared to that in calc 2 which was mostly U-substitutions. I really need a psychiatrist to image waves into the brain of a person who finds U-substitutions harder than gradients, curls, divs, & triple surface integrals of rectangular coordinates, cos for me it's a mystery. Your calc 3 teacher may have been far too lenient on you guys

Only about 5 weeks left and I actually have 100% in calc 2 and I’m going strong. I have a pretty good chance of getting an A with how it’s going lol. Update: I got an 90 on the most recent test so I’m at a 98. There’s one more test and I only need a 30 to get an A. Still going strong lol.

I'm finishing up Precalculus with a B, I got a 64 for my first exam, 84 the 2nd, 97 the third, 104 the fourth, and here comes the final. I need to make a 35 to stick to my B.

[@elisamarconell9991]

omg nice

[@jacobharris5894]

Excelling in a math class like that is always the best feeling. And it’s always nice not having to stress going into the final.

[@Christopher_Molina]

I finished with a 94, don't underestimate yourselves, people.

[@Coreyahno]

COVID college is school on easy mode. I’m in Calc 3 and the class average on our last test was 90. Before COVID when we were all in the classroom, class averages on every test in every math class was always in the 50-60 range. It truly is remarkable how distant learning has made everyone so smart! On an unrelated note I hear Chegg’s subscriber count is through the roof!

Going to take Cal3 and linear algebra in the fall

[@TheMathSorcerer]

Nice

[@charlesj7748]

I have not finished calculus II yet. But if you plan to take it make sure your trig identities are on point. It is trig heavy. Lots of trig substitution.

[@victorcamara2155]

Taylor polynomials and maclaurin series and power series were very hard for me back in the day.

[@edwarelrich2339]

Coming from someone who failed calc 1 once and passed calc 2 first time around, I’d say calc 2 was the hardest for me. Since my calc 1 class the first time was online, that made it a lot harder for me to grasp the concepts and material. Cylindrical and dishwasher methods from calc 2 made my time in that class a lot harder, and many of the concepts in general made this class super difficult. I’d recommend taking any calc class in person if you can, as there’s a huge difference with what you can take away from them!

[@normalvector4564]

I agree with calc2 particularly on the infinite series. At least in the perspective of an applied math major because some find infinite series abstract.

[@TheMathSorcerer]

yeah for sure!

[@jasonteh8389]

i self studied calc 1,2 & 3, and i think calc 3 is the hardest when grasping vector integrals such as line and surface integrals.

[@JoseDuarte-mb5hy]

I finish the calc series in a few weeks. Hands down calc 2 is the hardest of them. There are so many new concepts. This class has so many stuff going on. I had trouble with the whole integration and series chapters. Calculus 3 is more fun, but its hard to be able to visualize the planes and surface you are working with. So far the hardest parts have been surface integrals and these over vector fields. Parameterizing these can be tricky but not impossible. Learning online because of covid is hard, but stick in there and everything is possible!!

[@TheMathSorcerer]

Ya calc 2 is tough for people..I was making calc 2 videos yesterday I do love the series!!!!

[@tempestandacomputer6951]

Ive finished and aced Cal 1 and 2 after a lot of work. Reyman Sums is what i dislike the most so far as i find them tedious, but not the hardest. Up till now Taylor and MacLaurin Series in Cal2 are what took me the most effort to understand, but became easy once i grasped it.

[@elkpants1280]

Calc 2 was the most difficult for me since it had so many disparate topics, I had to retake it. Calc 3 was challenging but at least most of the class built on previous topics. I took diff Eq last and was an easy A.

[@KeBanger18]

Calc 3 was the hardest. I was flabbergasted at how I past.

[@KeBanger18]

But at the same time, I did take it in the summer when things are accelerated

[@jacobstarr9010]

The disk and washer method was so hard for me to understand. Once I finally understood it, I felt like my third eye just opened. It felt gratifying. So far, the worst part of Calc 2 is making small errors that cost me tons of points. That’s what’s the hardest. Work problems were difficult at first, but once I understood them, it wasn’t that bad. I haven’t done series yet but I’ll expect that to be difficult as well.

[@lilyyanhua165]

The only thing I found difficult pertaining to disks and washers was remembering which variable to integrate with respect to the other, but some how I managed to get an A in that class. I don't know if it helped that I was learning the area between two curves at this point too. I'm taking Calc 3 now and I have hope I'll do fine.

[@TheMathSorcerer]

yeah you will probably do awesome in calc 3:)

[@ItsTornHD]

I did the disk and shell method in calc 1 and it was pretty painful. Calc 2 infinite series was still the hardest for me though

[@jacobstarr9010]

Hey man I just took Calc 2 and I watched your video at the beginning of the semester. I ended the semester with an A and started with about a B+. What I will say about Calc 2 is that it is monumentally harder than Calc 1. In Calc 1 i probably studied only a few hours per week, but in Calc 2 easily 16+ hrs a week. Personally, the hardest concept for me to grasp was volumes (disk/shell method) but once I grasped it it became easy. Other than that, series were a close second, specifically involving conceptual questions. I remember studying nearly every problem in the book for the final and ended up getting an 88 on the final and a 93 in the class. By far, it was the hardest class I took this semester.

[@Dannyboy501]

I’m so glad I’m dropping my calc 2 class and I’m gonna change my major to avoid a class like it. It’s too much and it’s hard, stressful, and I swear I study take notes go to tutoring and my professors office hours as I get nothing. Literally I’m already like 4-5 weeks in calc 2 and it’s causing so much stress to me. I drove home last night and I cried for like 20 minutes because of how stressed I was and how hard it is. Until I finally found something else I wanna do as my major and I’m feeling a lot better now knowing that I found something else I’m gonna actually enjoy to learn

[@RvvN94]

Good luck :)

[@MrChaluliss]

I have yet to take calc 3, but calc 2 was mostly hard because the work load was just absurd. There is a lot packed into the class. And from a raw work required and attention required perspective the course took up roughly 3 (average) classes worth of energy for me.

[@StaticBlaster]

I always struggled with integration by parts and integrating with an exponential whether it be a single exponent or tetration. As well as struggling with the infinite series, power series, convergence/divergence tests. I'm pretty sure all of that falls within Calculus 2.

[@smob0]

Infinite series are great to learn about. You take an infinite amount of numbers, add them together and get ... 2? That was a mind blowing the first time we did something like that.

[@isaachester8475]

Funny, the disk/shell/washer method was easy for me because I could visualize it and it made intuitive sense. The hardest part of calc II, to me, was the infinite series because I just couldn’t wrap my head around the concepts very well.

[@mariellecarter2201]

Calculus two by far. At least for me, the disk and shell method were the hardest things in the class, but the series was next on the list, AST was my favorite test for some reason.

[@TheMathSorcerer]

Ya disk and shell was so hard for me

[@adammcallister9675]

I aced every math course I ever took. Blasted through Calc 1 like nothing. Got 100 on the departmental final. Calc 2 was an absolute ambush compared to ANYTHING else I have ever taken. Keep in mind I’ve taken everything hard. Ochem. University physics. Computer science. Statics. Dynamics. Thermodynamics. Calc 2 was a nightmare in comparison. Calc 3 was a breeze for me too. My instructor was great too! It’s just a horrible onslaught of completely new stuff you have zero familiarity with or foundation for just all jammed together. There’s really no way to improve it without major changes to how math is taught either lol. I didn’t struggle with shell/washer. I found it very intuitive and straight-forward and it sort of progressed from other problems we were taught. I had an awful time with a lot of the proof and series stuff we did. I crushed PFDs but most of my classmates struggled really hard with those.

[@StaticBlaster]

calc 3 and even calc 1 was a breeze for me. well actually on second thought, the first time i took calc 1 i struggled but the second time i took it, I received an A+.

[@ColeSaltzgaver]

just got out of calc 2 with a B+, I really enjoyed the infinite series like taylor and maclauren, as well as geometric and telescoping. I personally had the toughest time understanding Improper integrals and trig sub.

[@Jlundy12]

While I do believe Calc I was the easiest of the Calc courses, failing to comprehend the basics can set you up for trouble in the calc array. Calc 1 goes over the fundamentals and exactly why you use dy/dx or Riemann’s sum and integration. The coursework is fairly simple but the theories must be conceptualized before exiting this class. Calc II is definitely the hardest in terms of coursework. The problems assigned can take pages of work and there is room for error in the algebra. Trig substitution was killer and often discouraged me to finish an assigned problem. Luckily, the theories and concepts are easier to grasp in Calc II and the geometric analysis portion is fairly simple compared to Calc III. I thought Calc III was easier in terms of coursework but the theories and concepts were harder to visualize.

[@faceless2302]

Well that gives me a bit of hope for calc 3 at least.

[@camilofajardo9199]

I'm in calculus III and I've had to study basic stuff from calculus I

[@buellerferris]

I took Calc 2 3 times before I finally passed. But I was also overcoming a lot of trauma.

[@TheDarkzerox123]

In my opinion infinite series was difficult to understand because I was never really exposed to idea of if a summation would ever have a definite answer. A summation isn't hard to understand but being able to tell if it's converging or diverging with only the formula and no visual aid is very difficult. A lot of room to over think any unfamiliar summation that you've most likely seen before. What i mean by the previous sentence is that it's a bit different from your homework or class notes when you're taking the exam. I think it would've be an easier experience had we've been exposed to idea that functions in our algebra class can converge or diverge.

[@evebeeee]

I got a 98 in Calc 1 and have a C in Calc 2. It is brutal for all the reasons mentioned above. Not only the hardest math class, but the hardest college course I have ever taken.

[@ArkbladeIX]

Im gonna take calc III this summer. Calc II was easier than Calc I, but series and work problems were a big pain

[@Chris-ArmyPilot]

My daughter will a sophomore at Texas Lutheran University. She breezed through calc 1 as a freshman. I hope calc 2 and calc 3 will be easy for her as well WHILE majoring in biology.

[@TheMathSorcerer]

That's awesome. Yeah Calc 2 is usually the toughest! I am sure she will do awesome, Biology is no joke!

[@user-hb4cg1ef1f]

From hardest to least is Calc 3 (A), Calc 1 (B) and Calc 2 (A). After taking a break from math for several years, calc 1 was hard for me because I was learning new material while trying to remember old material I needed to know going into the class. For calc 2, after just taking calc 1 I was able to connect to the next stages of calc 2 with ease. Overall I found calc 3 to be the hardest because I couldn't visualize the 3 dimensional math problems as quick as I wanted to.

[@dereksaucedo3869]

I love all the series, the washer and disk method is definitely hard but it’s only cause that’s thrown at your face right off the bat and it’s so weird. I personally hate applying math (life scenarios) but enjoy it in other ways.

[@markmmmm9720]

I keep hearing Calc 2 was the hardest so I studied all summer for it before I took it and I got a A. It was tough but my dad told me you are defined by your work ethic so there is no quite in me. Because of him

[@Jason-bg7jc]

We did disk and shell method at the end of Calc 1. Not sure if it's on the final. Find out in a couple hours!

[@justinbeck560]

My worst test was the test with the shell/disk methods lol. the seq and series stuff is also a thorn

[@TheMathSorcerer]

Ya that disk/shell destroys people

[@jackdeago3639]

Hi!! Well it's really nice to see you personally ☺️ , where does " calculus 3" used ( in terms of physics specially) ??

[@Speed001]

The hard part of Clac 2 was juggling all of the concepts. Having to come up with orders of operations on my own because 'there is no order of operations'. BS, there should be a series of stuff you can go through based on the given problem. But yeah, remembering all the steps and possibilities for each equation was hard. Overall, once you get used to it, it's not that bad.

[@mikuculus3720]

I mean we had LIATE Logs inverse trig algebraic functions and exponential functions but yea the thinking required is brutal

[@aj28099]

Personally, I thought calc 2 was the easiest then calc 3 and oddly I struggled the most in calc 1

[@skraxx]

To me, I think that just says u had trouble with the base initially but once you got it you got it.

[@zekayman]

I just finished Calc. II with an A! It has been 5 years since I took Calc. I as an AP class in high school, so to anyone reading this that may be in a similar boat as me, just know that the main takeaway that you'll need going into Calc. II from Calc. I is how to do derivatives (product rule, quotient rule, chain rule, etc.). You may want to brush up on limits as well, but overall, Calc. II is very doable without a solid background in Calc. I.

[@isaacjohnson8752]

Our course did solids of revolution and work in calc 1. But the infinite series rules gave me the most trouble, and for that reason I think calc 2 was the hardest.

[@smiggyballs6636]

I feel like the infinite series was not bad, it was very easy. It was fun, as you said, but the taylor and mclauren series (unsure if I spelled mclauren right) really kicked my ass, I just couldn't get my head around how the equations worked.
