We are contstructing a quarter at each x in our interval. The sum is the sum of all the "quarters" (each with depth dx).
nice
>cramming for ap calc test tomorrow>1.5 speedhere we go xD
right there with you.
1 year later. doing the same thing
Here we go again boys
same bro 1.5x speed is perfect lol
Keeping up the tradition ...exam in 7 hours
I love how he teaches. Really wish more teachers and textbooks would be as effective as he is.
I think it's just the different way he teaches. I bet if I had him as an instructor, I'd find someone who could explain some things better for me.
Thank you so much Sal, the formula makes so much sense now.
There isn´t any good explanations in Swedish when you study math. Good for me is someones like you. :)
What program is he using? Sal is a good drawer.
I know I'm 5 years late, but whatever. He's using SmoothDraw
I thought he was a cabinet
love you khan academy
I would not be able to pass my calculus classes if it wasn't for you, thank you so much.

It is not true coin right? because radius changes when you move on x axes ....?
what if you have multiple y = functions
Phil V that's the washer method
when you got to the standard derivative stuff, I was like...what kind of witchery is this ?!?Something i definitely need to look up
Now I know why the name of the method is disk
please do a video on ricci flow. please :)
wizard hat
I was just wondering why these new videos are not in a playlist :/I'm using software to download the videos in one go, it'd be more comfortable if they were placed in a playlist
lovely
Amazing
Man this stuff is easy
I must be clear. It is a wizard's hat. Not just any wizard's hat but Gandalf the Grey's hat.
wait, I thought dx doesnt represent delta x?
why r=x^2 ??
oh okay okay, understood, f(x)=x^2 thats why,
literally the same prob Im doing lmao ftw
Thank u
it does
