I know this integral is an integration by parts, but what is the correct approach to breaking it up so that it becomes solvable?

Thanks, but according to my notes

u=1/3x^3

du=x^2

dv=3x^2sin(x^3)

v=-cos(x^3)

does this make sense? Your way seems much more logical. - Apr 20th 2009, 12:48 PMTheEmptySet
