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 = … WebApr 12, 2024 · Now, we'll need to take a peek at our derivative table, and recall that: d dx [csc(x)] = −csc(x)cot(x) This is exactly what we have in our integral EXCEPT there's a negative sign we need to take into account. So, we'll need to multiply by -1 twice to take this into account. Note that this does not change the value of the integral, since −1 ...

WebHere's an example where an approach like yours could work: To calculate ∫ ( 2 x + 1) 6 d x, we could note that we have "stuff" to the power of 6, i.e. u 6 where u = 2 x + 1. We already know that. ∫ u 6 d u = 1 7 u 7 + C. so, to account for the chain rule, we might try subbing in u = 2 x + 1 and dividing by d u d x = 2.
