How to take integral of sin 2x
WebLet's look at the integral as follows: If u = sin x and d v = sin x d x, then d u = cos x d x and v = − cos x. So we have ∫ sin 2 x d x = u v − ∫ v d u = − sin x cos x + ∫ cos 2 x d x If we add ∫ sin 2 x d x to both sides, we get: ∫ sin 2 x d x + ∫ sin 2 x d x = … WebLearn how to solve integrals of exponential functions problems step by step online.
