Given that u and v are functions of @ and the fact that, u = 7x8 dv = - sin(x) dx Find du and v. du = U =Given that u and v are functions of a and the fact that, u = cos (Ex) dv = 70x dx Find du and v. du = U =Consider the integral /x In(x) da: Applying the integration by parts technique, let U = and du = da Then uv - lvdu = da
