How to find cosine from sine

In this blog post, we will provide you with a step-by-step guide on How to find cosine from sine.

Deal with math problems

If cos A = 5/13, how do you find sinA and tanA?

sin ( 90° - A ) = cos (A) = b / h. and. sin ( 90° - B ) = cos (B) = a / h. To keep going: tan (A) = a / b. tan (B) = b / a. cot (A) = b / a. cot (B) = a / b. sec (A) = h / b. sec (B) = h / a. csc (A) = h / a. csc
