Derivation Trigonometric Identities - Pythagorean Identities

Hi! I'm Mateo Patiño, and I record math and physics videos. Most of my content is based on problem walkthroughs and mini-lectures where I go over a particular concept. Feel free to subscribe if you like the content or give me any feedback on things you'd like me to improve! 🍎

In this video, I show you how to derive trigonometric identities. The identities I derive are called Pythagorean Identities because they originate from a right triangle inscribed in the unit circle. In this particular lecture, I will derive the tangent and cotangent identities from the sine + cosine identity, which I derived in Part 1.

Don't hesitate to ask me any questions 😃
