Pre-Calculus/Foundations 10: Proof of the identity Sine/Cosine Equals Tangent

Показать описание
A simple and quick derivation of the popular tangent identity! If you've seen this identity at school but don't know why it's true, check this video out!

This is my second video going over an identity/formula! I hope you're excited for my upcoming Foundations of Math 10 videos as well as more proof videos!

All feedback is of course, appreciated. If you would like to see any topics explained, or any formulas proved, comment down below and I'll attempt to make a video to the best of my ability :)

If you have any questions, you may email me as well.
