Answer :

Given


Let us first integrate and find f(x)


Using uv rule where u and v are functions of x



Here u = t and v = sint






f(x) = - xcosx + sinx


f’(x) means differentiating function with respect to x


Using uv rule for differentiation where u and v are functions of x


(uv)’ = u’v + uv’


f’(x) = - (1cosx + x(-sinx)) + cosx


f’(x) = - cosx + xsinx + cosx


f’(x) = xsinx
