Verifying trigonometric identities

If all else fails turn everything into sine x and cosine x and see what happens! Usually there is lots of algebra between using the trig functions.

Trigonometric Identities (Revision : 1.4

The “big three” trigonometric identities are sin2 t + cos2 t = 1. (1) sin(A + B) = sinAcosB + cosAsinB. (2) cos(A + B) = cosAcosB ? sinAsinB.
