The proof is as follows. Cos 2A = 2Cos2(A) – 1 Cos 2A + 1 = 2 Cos 2 ( A ) (1 + Cos 2A) /2 = Cos 2A i.e Cos 2A = (1 + Cos 2A)/2 1 + Cos2 A( -1/2 ) + Cos2 A

sin(x y) = sin x cos y cos x sin y How to integrate cos^2 x using the addition formula for cos(2x) and a trigonometric identity. The same is true for the four other trigonometric functions. By observing the sign and the monotonicity of the functions sine, cosine, cosecant, and secant in the four quadrants, one can show that 2 π is the smallest value for which they are periodic (i.e., 2 π is the fundamental period of these functions).
