hoe to integrate byparts

Hi,

In calculus, and more generally in mathematical analysis, integration by parts is a rule that transforms the integral of products of functions into other (ideally simpler) integrals. The rule arises from the product rule of differentiation.

If u = f(x), v = g(x), and the differentials du = f'(x) dx and dv = g'(x) dx, then the product rule in its simplest form is:

        ∫ u (dv/dx) dx = uv - ∫v (du/dx) dx
