Integration by parts is just the reverse of the chain rule:

d(u*v) = d(u)*v + u*d(v)

integrated and re-arranged:

I(u * d(v)) = u*v - I(d(u) * v)

That's how I remember it. As for implementing it, fractoid is right...find:

(the tough to integrate part)*(the easy to integrate part)

and use:

d(v) = (the easy to integrate part)

sorry for my use of d() to signify d()/dx...I know real mathematicians are rolling in their graves (at least the dead ones who frequert GameDev [8^)
