WebWe have the Pythagorean trigonometric identity given by sin^2x + cos^2x = 1. Using this formula and subtracting cos^2x from both sides of this identity, we can write it as sin^2x + cos^2x -cos^2x = 1 - cos^2x which implies sin^2x = 1 - cos^2x. Hence, the formula of sin square x using Pythagorean identity is sin^2x = 1 - cos^2x.
