Area Of A Triangle 1/2absinC
The area of a triangle is ½ the base X perpendicular height. If we don’t have the perpendicular height, there is another formula we can use: 1/2absinC which we look at in this video. We need two sides and the angle in between. This will...

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.
