WebExplanation: Let us first simplify sin 2 x, using the trigonometric identity. Now, using the simplified value for sin 2 x, the integral converts to: ∫ sin 2 x = x/2 - (sin2x)/4 + c [Since the integral of cosax = sinax / a] where, c is the constant of … WebWhat Are Sin Squared x Formulas? Using 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.
