This comment section sure has a lot of egos. Math brainiacs feeling the need to show off their mad skillz: humility might do you some good. It's fantastic that this stuff is incredibly easy for you - it isn't for everyone, and proclaiming your genius to the world serves no one, it only comes off as arrogant. If this is below your level - great, go to some higher level videos. In the meantime, show some respect for MIT and appreciation for their work in making good education open to everyone, and some consideration for your fellow students who may have more trouble with this stuff.

[@s.a.c.l.1893]

+Tinydude10 This is truly fascinating. Further ago, the physically superior human would find no fault in demonstrating his own superiority, whereby others would submit in his presence. But today, we do not see the same consequence in the intellectual realm.

[@s.a.c.l.1893]

+ Tinydude10 For reference, I submit quickly to my intellectual superiors, that's how you learn, and that's how you expose fakes. In so doing, you're relearning everything through them, and this will reveal what they truly know and what they don't, to distinguish between a fact regurgitator and a true mathematician. And of course, that's how you learn. In BJJ, white belts can learn from blue belts, apparently not the case in maths for most people.

[@oldcar8592]

I really like that the instructors at MIT spend the time to write the topic on the board which reinforces the point of their discussion. And they all have good penmanship which allows the student to concentrate on what he is saying, not trying to interpret the writing. I also like they're using blackboards and chalk which show up nicely in the videos. When my school changed to whiteboards there were times when reflections obscured the writing and some of those markers had a distracting smell.

[@mousedorff453]

I like how people in the comments section are mulling over the Professor's treatment of the material in this course, completely forgetting the fact that courses like these will usually have textbooks associated with them to augment learning and the professor's job is NOT to regurgitate things that can be found in a textbook but to focus on the key concepts required in problem solving. It amazes me that some people feel that there's a need to do 10 whiteboards worth of derivations in a 50 minute course when the focus should ALWAYS be on the concepts, with the professor encouraging students to look up the derivation or the individual proofs. It's good that the professor managed to do the derivation at the end, cos it just reinforces the concepts and also provides a general methodological framework which students can then use to solve general problems.

[@fisherli7187]

the website stated that there's no book accompanied to this course, don't just think it's a good lecture cause it's from MIT. The lecture is disappointing.

[@bigbluebuttonman1137]

@@fisherli7187 I feel like if you’re going to not have a book, then your lectures better be pretty amazing, with extra resources for learning that aren’t bought books. The other thing…half of math lectures (probably more) always lack some crucial historical context. Why was this made? Why did it matter? And the problems are so abstracted away that it loses some of its magic, just turning into esoteric stuff that’s solely important in esoteric isolation. And, I’m NGL…I kind of want some sort of strong personality from my math professor. I had at least two of those, and it made everything way smoother and better. I just don’t see a lot of enthusiasm from this guy.

Algebra and trigonometry. Sine cosine and tangent basics taught in high school algebra, and trig. Without these, this all seems like a bunch of random Greek characters and woo.

Also, a few cheap used school text books from amazon would do the job...and would also provide a good structure for the prerequisites that this course assumes are present. In fact, I would recommend the book route rather than the Khan route, and then use Khan as a reinforcement to test your knowledge, as the website includes practice tests, but does not provide the linear progression you need.

America's Elementary, Middle and High school level of education is deplorable relative to schools in other countries. Their higher level of education is phenomenal. Schools like MIT, Harvard, Stanford and Princeton are synonymous to great success all over the world (as you said). I'm currently studying at Cambridge and I'm watching this lecture :P no shame in that because it IS VERY GOOD. Sadly that standard can really only be met by students who have had a much more rigorous studies prior to entering their secondary level of education. People from other countries (as you said) will flock to your higher level institutions because they are more likely to meet the standard.

+xEAx1x Not true, if you adjust for demographics, whites in America are average by western European standards. North East Asians in the US perform similarly to Northeast Asians in Northeast Asia and people from third world countries probably do better in the US than in the country of their ancestry. It only looks bad if you assume that all peoples are equally educable and have the same innate ability. An assumption which I see no reason to make, and hence the need to control for ethnicity.

[@thehomiebearfifa3528]

The Eternal Hermit is this knowledge from your numerous years spent studying anthropology. Lmao, never thought I'd see such Idiocracy in one of MITs videos, usually stupid people don't come here

[@lindsaypinedamendoza90]

The education when terribly because of the civil war and world wars

[@Smile2516]

I have just one question: How 1/2 (2Xo)(2Yo)= 2XoYo=2? If we do 1/2 *2 (XoYo) we are left with XoYo which i don't think is equal to 2 :X

[@Smile2516]

Andrija Čolić Thanks-I think i got it ^^

[@aMulliganStew]

it bothers me that no one in class asked that question.

[@Smile2516]

Well, they asked another questions-it's something that they understand I suppose ^^

[@tomjordan6092]

You are taking out a factor of 2. (2Xo)(2Yo) = 4XoYo . If Xo and Yo = 1 and you plug it in (2*1)(2*1) = 4. Then you multiply by 1/2 and get 2

[@Smile2516]

Thanks ^=^

[@mindhypo]

Thank you MIT and my dear sir. I need calculus to study MIT physics. So I started my journey today. I could understand the whole lesson. Thank you again.

[@theintrepid7583]

Currently a sophomore in high school. I've heard a lot about calculus over the years and about just how powerful and beautiful it is. About 20 minutes in is when that rang so true for me.

[@muhammadehtisham1593]

Today I have statrted this course. This is really awesome. I just want to know which book I should follow for this course?

[@mitocw]

The textbook listed in the syllabus is: Simmons, George F. Calculus with Analytic Geometry. 2nd ed. New York, NY: McGraw-Hill, October 1, 1996. ISBN: 9780070576421. For more info, see: ocw.mit.edu/18-01F06. Best wishes on your studies!

[@hareshjadav9148]

Thanks mit

[@meowwwww6350]

@@mitocw I love MIT physics and it's fascinating

这老师真好， 看了这个课之前，我以为我遇见的是好老师。 我遇见的数学老师，从来没解释过，坐标系里，其实是很多个变量，而且重复使用了x 和 y 来表示不同的东西。 而这一点是非常重要的，也是复杂的根源。

[@Abss0966]

why do you start with derivatives without going through limits and continuity first ?

[@SexualPotatoes]

Because MIT students should already know those

[@JudyAbbott494]

Sexual Potatoes! :D

[@iLoveTurtlesHaha]

@sexual potatoes but MIT states that the prerequisite for this is high school algebra. You don't learn limits in algebra. Being an MIT student does not mean you know limits. Why stop at limits? why not know full calculus too... they are MIT students no? They should know it all before stepping foot on campus.

[@diegosaul8874]

Thank you from Colombia, it is pretty useful!

[@user-ls8gi9zn4d]

We never could know what we learn in KZbin or Bilibili. Thanks MIT , Peking University and other universities those could really bring knowledge to me.

[@Bobby812017]

Wow they start by differentiating e^(arctangent(x))d/d. My community college we start with xd/dx

[@OHYEAHDUDES]

Man I love chalkboards n the sound the make :D

[@coldkick]

@stiglaa X value - any value on a graph's horizontal axis Y value - any value on a graph's vertical axis slope - the value which is the change of x and y values between two points tangent line - the slope of a curve at any given single point. In this video he estimated the tangent line by looking at how the graph curved in that area. (Geom. Interp.)

This man's jugular is noticeably extended indicating a high degree of self-induced stress. Dangerous work well performed.

[@TanmayNandanikar]

Can I complete and this while thoroughly understanding it within 14 days?(i mean all the 35 lectures in this course) I have a two-week vacation and nothing to do..

[@FsimulatorX]

nope because you will forget 80% of it in a month and 99% in a year

[@potatosalad6534]

Did you do it?

[@TanmayNandanikar]

i just saw these replies; i did finish all the lectures back then (only half in 14 days and next a month or two later) but quickly realized it isn't worth much if i don't do the problem sets(or at least part of them); didn't do the problem sets since now i have calculus in my high school curriculum

[@peterlamont647]

FsimulatorX is quite right...binge learning usually results in binge purging of memory by the brain shortly thereafter...unless you consistently apply what you learn for a time _in_ _practice._ That is to say, continuously test yourself for a longer period of time after a subject is learned. Computers are great for this! Just make a program to randomly generate problems for you to solve. Load and run once a week for an hour for around a year, and you'll have a working knowledge of it for the long term. In addition, making the program will help solidify the knowledge all by itself, as in the program's creation you are learning by teaching. This is what I use my retro computers for quite often. It's a fun way to interact with my computer collection in an extremely useful way. In addition, sometimes I'll look at some software online (browser based) which does this to some degree, and then see if I can recreate it myself doing my best to get the same style UI / data entry scheme while tailoring it to my preferences. Then I can load my practice programs from magnetic tape any time I want!
