How do you evaluate cos^1(1/2) without a calculator? Socratic
Cosine Of 0. In the illustration below, cos(α) = b/c and cos(β) = a/c. Thus, cos 0° value = 1.
How do you evaluate cos^1(1/2) without a calculator? Socratic
Web cos x = 0, when x = ±π/2, ±3π/2, ±5π/2,. 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°. It means that cos x vanishes when x is an odd. Thus, cos 0° value = 1. Web it is the complement to the sine.
