Listen, Sal. I love you.

[@faichalayeva3677]

Even though my high school didn't have calculus courses, I started college knowing what to expect in calculus. Thanks to Khan Academy. Thank you.

[@FlareGunDebate]

Normally I 100% understand everything Sal say but this video scrambled my brains. Now that I'm oriented it makes sense but the notation is subtle. I think throwing some numbers in the mix would have helped me.

[@UziMusic]

Yep, this is an absolute word soup, i haven't understood any of it, and its been over a week of everyday trying and trying.. it's not explained properly by anyone..

[@caralisaswan]

I LOVE KHAN ACADEMY!!! :)

[@TomAustinIII]

Gonna have to keep watching videos like a drone over and over. Had to rewind a lot. But the benefit is that you can rewind it as many times as you want. (Watches again)

[@Cosme422]

I love it! Just hope one day I can watch it in English :-)

[@TRADERSFRIEND]

You are a genius......

[@benno19891]

This is saving my life

[@markcarranza2032]

[@mahkramahkra7848]

Understanding, simple, and fun
Thanks sir for explaining

[@ian.ambrose]

Please shut up.

[@78anurag]

Calculus is easier than I thought

Join the club young padawan.

[@mdshoyaibsarker4918]

That's awesome ❤

[@mohamedbadawy5691]

Awesome!

[@debendragurung3033]

Is c just a dummy domain in variable x , like some test charge in Gauss Electric Field Theory. Its my second encounter with use of such a hypothetical supposition. I thought Maths has got ridden of such supposition, but still cannot. Thank you so much this and other two videos on Fundamental theorems, cleared a lot though created some other confusions. I came to this video when I got stuck on multivariable calclulus. Now I have a lead how to go about exploring, lets hope I wont go crazy.......

[@tonghaoqiu5610]

Hi I just have a couple questions on FTC. What exactly is FTC part 1, my prof did horrible job on explaining this. Is part 2 just saying the area from pt X to pt D is equal to the integral been evaluated on the interval [C,D] subtract the integral been evaluated on the interval [C,X]? And what do you mean when you say F'(X) = f(x)?
Thanks!!

[@rammaddirala6857]

watch his original video on FTC 1, Ik its been 6 years but yk better late than never :)

[@rhoadess]

The Fundamental Theorems of Calculus would make great tattoos! But I think I'll pass. Perhaps a T-shirt.

[@gosucoaching]

Wait... I'm 26... I should be inventing this stuff by myself not watching it on youtube!!! O_o

[@ShanBojack]

You're 36 now so how's it going

[@johnnyx767]

shouldnt of watched this hungry

[@oluwakoredeonasanya3267]

10 years later and I've made the same mistake as you

[@chestermicek]

Calculus is as boring to me now as it was 30 years ago.

[@kevin_lin]

You enunciate fundamental too much

[@warmaxxx]

not everyone is issac newton
