Evaluate the following integral using integration by parts.

âˆ« (x cos x) dx

Use the integration by parts formula so that the new integral is simpler than the original one. Choose:

A. âˆ« (x sin x) dx

B. âˆ« (sin x) dx

C. âˆ« (cos x) dx

D. âˆ« (cos x) dx

Evaluate the integral:

âˆ« (x cos x) dx =

Applying integration by parts, evaluate the following integral:âˆ«x sin(x)dx

a. âˆ«x sin(x)dx = x(-cos(x)) – âˆ«(-sin(x))dxb. âˆ«x sin(x)dx = -x cos(x) – âˆ«sin(x)dxc. âˆ«x sin(x)dx = -x cos(x) + âˆ«cos(x)dxd. âˆ«x sin(x)dx = x sin(x) – âˆ«(-sin(x))dx
