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.

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]

[@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 believe that the area of a triangle is 1/2 base x height.

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. I agree, Khan Academy is a good resource. 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

[@ngrader]

24:32 I think 20 years later, I finally understood what my alcohol soaked brain didn't as a student. Seems simple now, but I never followed my prof in school when he did this. This guy does a good job explaining that contortion.

[@caseystack2711]

What is wrong with most of you commentators? If you are too smart or too good for these lectures then go somewhere more challenging. No need to show off how smart you are by stating how simple the work is for you.

[@joeyclemenza7339]

+Casey Stack insecurity... which is why they're bragging on the internet, for the most part.

[@joeyclemenza7339]

+Casey Stack also, the purpose of calculus is not in it's varying levels of difficulty, but in it's application.....which can yield more than the creative mind could conjure. math is essentially a tool used for creation, and not a d**k measuring contest.

[@pawanmishra9342]

why do you even read the comments, its how people express what they understand,

[@bryancbg4684]

I’m doing this in my high school class and I don’t understand fuck. I’m like the only sophomore in that class with a bunch of seniors. It sucks.

[@twistytheclown9120]

Excellent how the instructor uses proofs to demonstrate examples. Many instructors just say, "this is the rule" ....

[@jamesqiu6715]

those 2 questions asked at 23:15 and 24:30 can be easily answered by 14 year old middle school student in Asia ! Good job MIT students!

[@adnanali2773]

When I heard those questions I was wondering whether they're MIT students or some guests. LOL

[@RomanesEuntDomus.]

Great video. Last night I could sleep, and accidentally found this video. Needless to say, I fell asleep in five minutes

[@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 ^=^

[@Emiffe]

I remember I would watch this series of lectures while I was taking both Calculus I and II at my university. I dominated those classes, and I think I owe a big thanks to MIT OCW because I believe these lectures made a significant contribution to my understanding of Calculus. For me, these lectures have become as important and memorable as the real classes I've taken at my university. Thank You!

[@GGGJJJay]

People are criticizing how "easy" this stuff is . But to be fair I honestly I don't think Prof David Jerison (no offense) is doing a good job explaining to students that are new to this subject

[@markomak1]

+GGGJJJay People are expected to have some familiarty with calculus i think.

[@joeyclemenza7339]

+GGGJJJay that's essentially what opencourseware is...an introductory level of varying college courses and subjects, for beginners and advanced alike.

[@peterlamont647]

Most of these students know calculus already from high school...If you got into MIT, there is zero chance you don't already have a working understanding of calculus, unless you were accepted solely for being born genetically correct.

[@peterlamont647]

...and if that was the case, and this is the intro they got..over to gender/race studies they go to be radicalized!

[@kaushikdr]

Totally agree - he starts with limits without ever explaining what a limit is XD

[@danieloctopus1004]

This Lection was in 2007! here in 2022 i read in the back o tshirt of school boy "CORONA" (24:31) hahah What a prophet he is.... ahead of his time!

[@rahulroyale001]

very good explanations.. description doesn't enlist his name? i am very thankful to MIT for putting these kind of videos in public domain.

[@hieucao3871]

For a very first time in my life, I understand calculus. Thank you so much 🙏

[@Patel_krisshna]

Anyone watching in 2024 😮

[@biffboffo]

This prof has boss-level chalkboard penmanship and speed.

[@msbalzgiip7365]

28:10 - I've done an interactive graph of this exercise at: www.desmos.com/calculator/lfc29dwtt6

[@vanchark]

Do these courses pretty much teach you the same thing that a high school AP Calculus AB class would?

[@heroman1596]

yes

[@lucasm4299]

Hero Man What about AP Calculus BC? I know it covers more material. Integration by parts. Parametric Equations. Taylor Series.

[@legoffour8466]

That is on here, but I HIGHLY recommend supplementing this class with a more complete textbook. They are covered, but their work on Series is a little deficient. I hope this is still useful to you, 6 months later!

[@ABugWithTheBigDreams]

They do not waste their time, they learn only required things.
