Integration by Parts: integral of udv = uv - integral of vdu
I think I find their derivatives are the same, then the formula is proven.

if I let 'S' stand for the symbol of integration, S udv = uv - S vdu
I started by solving Sudv by doing a double integral : SSudv and got
(u*u/2)dv + uv
and so on, but I don't know where to go from there or if I'm approaching it
correctly.

Please help.
