About

In these sessions, we’ll explore various ways to prove the compound angle formulas for sine and cosine — including methods from pure geometry, vector analysis, and complex numbers...
Please note that these sessions require you to have a good understanding of theorems such as similar triangles, vertical angles, as well as the basics of complex numbers.
