How do you integrate cos^3/2(x) or square root of cos^3(x), I know for the integration of cos^3(x) you break it apart to cos^2(x)cos(x). Then chnage that to (1 - sin^2(x))(cos(x) and do a u subsitution, with u set equal to sin. However, because of that square root it completely changes the problem, or at least in my eyes it does. Step by step help would be appreciated. Thanks.
