Question

Integrate with respect to x, 2 sin (3x)

Answer 1

Step-by-step explanation:

Integrate by parts using the formula ∫udv=uv−∫vdu ∫ u d v = u v - ∫ v d u , where u=x2 u = x 2 and dv=sin(3x) d v = sin ( 3 x ) . Simplify. Combine cos(3x) cos ( 3 x ) and 13 1 3 . Combine x2 x 2 and cos(3x)3 cos ( 3 x ) 3 .
