Proving the Pythagorean Identity

Here I go over the Pythagorean identity, how to prove it, what it's uses are, and how to not memorize the other identities. #pythagoreantheorem #trigonometry #precalcproblems #precalcreview #unitcircle #proofs #triangles

Next video will be on de moivre's theorem. What would you guys like to see afterward? Edit: In the video I said "if you know cosine squared of theta plus sine squared of theta equals theta..." near the end of the video. I meant that if you know cosine squared of theta plus sine squared of theta equals one, not theta. Sorry for the mistake.

Hello. Thanks for this wonderful video! Could you please make a tutorial about matrix diagonalization?

[@HarshitBroShukla]

Hey there, can you consider making videos on trigonometric identities.😀😀😀
