WebMay 9, 2016 · Explanation: Let's draw a right triangle with an angle of a = cos−1(x). As we know cos(a) = x = x 1 we can label the adjacent leg as x and the hypotenuse as 1. The Pythagorean theorem then allows us to solve for the second leg as √1 −x2. With this, we can now find sin(cos−1(x)) as the quotient of the opposite leg and the hypotenuse.
