Question

integral of x sin x dx​

Answer 1

Step-by-step explanation:

Solution. We want to integrate by parts, taking u = x, dv = sinx, du = dx, v = −cosx: ∫ x(sinx)dx = −xcosx + ∫ cosxdx = −xcosx + sinx + C

Answer 2

Answer:

. We want to integrate by parts, taking u = x, dv = sinx, du = dx, v = −cosx: ∫ x(sinx)dx = −xcosx + ∫ cosxdx = −xcosx + sinx + C .
