**At about 6:45 I say "opposite over adjacent" when I meant "opposite over hypotenuse". Sorry about that!
This video is a geometric proof of the Compound Angle identity sin(x+y) = sinx cosy + cosx siny. It is step by step, and requires only knowledge of basic trigonometry and algebra fundamentals to understand.
