Cosine Of 0. Thus, cos 0° value = 1. It means that cos x vanishes when x is an odd.

Web it is the complement to the sine. Thus, cos 0° value = 1. In the illustration below, cos(α) = b/c and cos(β) = a/c. Since the cosine function is a periodic function, we can represent cos 0°. Web cos x = 0, when x = ±π/2, ±3π/2, ±5π/2,. It means that cos x vanishes when x is an odd.
