Pi Approximation Trick - Calculator - Derived Using Pythagoras's Theorem
1. First get yourself some graphing paper.
2. Draw a circle with a radius 1, emanating from the point (0,0) on your graphing paper.
3. Join the points (1,0) and (0,1) up with a line using a pen or pencil.
4. This line should be √2 in length.

This video contains a visual proof that demonstrates why 1-(1/3)+(1/9)-(1/27)+(1/81)-(1/243)-...=3/4. It can be found on page 406 of the book 'Real Analysis: A Long-Form Mathematics Textbook (2nd Edition)' by Professor Jay Cummings. As an added bonus, there is a short clip (23 iterations) where you can zoom into the final image of Jay's proof. The art was created by Tiago Hands.

In this video I demonstrate how to quickly get the inverse Pythagorean theorem using what I call the 'sin²x+cos²x=1 method'.
This will get you to your destination much quicker than most proofs you find on Youtube.
