Then, by definition of the arcsine function, sin θ = x, where − π 2 ≤ θ ≤ π 2, and cos ( arcsin x) = cos θ. Using the Pythagorean Identity sin 2 θ + cos 2 θ = 1, we obtain sin 2 θ + cos 2 θ = 1 cos 2 θ = 1 − sin 2 θ cos 2 θ = 1 − x 2 cos θ = 1 − x 2 Since − π 2 ≤ θ ≤ π 2, cos θ ≥ 0. Thus, cos θ = cos θ, whence
