Why is pi here? And why is it squared? A geometric answer to the Basel problem
A beautiful solution to the Basel Problem (1+1/4+1/9+1/16+...) using Euclidian geometry. Unlike many more common proofs, this one makes it very clear why pi is involved in the answer.

Pythagoras Theorem Proof - Pythagorean Theorem
The Pythagoras Theorem says that, for any right angled triangle, the square of the hypotenuse is equal to the sum of the squares of remaining two sides.Out of all the different way of proving it, we will learn it by using the concept of...

The Quadratic Formula - Why Do We Complete The Square? INTUITIVE PROOF
The quadratic formula is really useful, but its derivation is confusing to many. Like what is the point of "completing the square" anyway? In this video, I show how "completing the square" has a geometric interpretation--you are actually...
