cos hypotenuse θ = hypotenuse sec adjacent θ = opposite tan adjacent θ = adjacent cot opposite θ = Unit circle definition. For this definition θ is any angle. sin. 1. Jun 7, Tan really likes Cos, and Cos likes him back but they'e both in a difficult situation because of Tan's relationship with Sin. It's really complicated. If θ is substituted for m∠A, we establish the following relationship between sine and Solution: If A and B are the acute angles of a right triangle, sin A = cos B.
