Use the relationship from the previous step to write an expression for A 2 in terms of P and B. A 2 = (A) (A) Web17 apr. 2024 · This equivalence relation is important in trigonometry. If a ∼ b, then there exists an integer k such that a − b = 2kπ and, hence, a = b + k(2π). Since the sine and cosine functions are periodic with a period of 2π, we see that. sin a = sin(b + k(2π)) = sin b, and cos a = cos(b + k(2π)) = cos b.
