WebbUsing one of the trigonometric identities, we have sin 2 x + cos 2 x = 1. Subtracting cos 2 x from both sides, we get sin 2 x = 1 - cos 2 x. Thus, one of the sin squared x formulas is, sin2 x = 1− cos2x sin 2 x = 1 − cos 2 x. Using one of the double angle formulas of cosine function, we have cos 2x = 1 - 2 sin 2 x.
