1,sinx,cosx,sin 2x,cos 2x, are orthogonal. To see this, we use the following identities: sinmxcosnx = 1. 2. (sin(m + n)x + sin(m − n)x) sinmxsinnx = 1. 2. (cos( m  Problem 4PQ: Simplify sin(2x) cos(x) + cos(2x) sin(x). Solutions for Problems in Chapter 3.7 is solved.

T.ex.

cos(2x) = cos 2 (x) – sin 2 (x) = 1 – 2 sin 2 (x) = 2 cos 2 (x) – 1 Half-Angle Identities The above identities can be re-stated by squaring each side and doubling all of the angle measures.
