Alright I have a review questions I need help on for this upcoming test. So any help will greatly be appreciated and I'm sure provide to me getting an A on my next test which I surely need.

Show that one of the substitutions u = e^3x, v = x-3, w= cos(3x) can be used to find an explicit antiderivative of x*sqrt(x-3). Find an explicted expression for integral x*(x-3) dx.

Again thanks.
