i really appreciate that you explain how to find the equation, not just what the equation is. i'm awful at memorizing equations but i can usually reason things out pretty well. also, your videos (in conjunction with some other youtube-teachers) are really helping me prepare for my AP test (this Wednesday) so thank you
Your videos help tremendously. Thank you so much for your time !
I’m glad he went over the arithmetic in 8:50. I would have forgotten how to do it otherwise.
lolollololololo
Thank you very much . Your channel is really the best one for learning Calculus.
Thanks! It is much more helpful than my college professor
I wish my teacher would explain like that
Khan is brilliant.

Because it is the height of the function above the x-axis
(1^2)/2 = 1/2

That's a pretty hefty diet you got there.
Like a hefty amount of food? I mean, we don't know the units. It could be pi/6 cubic centimeters or something.
