Volume of a Sphere: Three Different Derivations

This video is dedicated to Kalid Azad, who was the first to help me really understand integration as more than just some arbitrary algebraic process. Anyone interested in mathematics at any level should check out his mindblowing course on Calculus:

I like your enthusiasm, i will grow up to be a teacher like you.

this is a great video and a great lesson! understanding how we get our formulas makes math so much easier to comprehend.

There are quite a few ways to derive the volume of a sphere, another one is using double integrals by using the equation of a sphere. It is amazing the numerous solutions to this.

My god!
I never thought about that
Now i wonder why do they not teach us in schools
So happy after watching this video

Wow! what a passionate mathematician...

Hello teacher Woo I have a question. What is the expansion of the sphere area? and to which length does the derivation of this field (4.pi.r^2 ) lead us? Actually i am wondering 8.pi.r. I hope you answer me thank you :)

If u spin a coin doesn't it work too?

When someone laughed I felt so relieved that maybe I wasn't the alone thinking "omg, I don't understand this weird 'f', help"
