WebAccording to the Pythagorean identity of sin and cos functions, the relationship between sine and cosine can be written in the following mathematical form. sin 2 θ + cos 2 θ = 1. ∴ sin 2 θ = 1 − cos 2 θ. Therefore, it is proved that the square of sine function is equal to the subtraction of the square of cosine function from one. Webcos(x) + 1/2 cos(2x) + 1/4 cos(4x) ...
