I tried to solve this integral but i was not able to get an answer. I tried foiling the integrand and go from there but was not able to succeed.
integral from 0 to pi (xsinx+cosx)(xcosx+sinx)dx
THey gave me a hint
Hint: sinxcosx= 1/2sin2x
So far i just foiled and got the following for the integrand:
x^2sinxcosx + xsin^2x+ xcos^2x + cosxsinx dx
