In this section, we will begin investigating some more advanced techniques for integration – specifically, integration by parts.
Integration by Parts is essentially a product rule for antidifferentiation. It comes from the product rule from derivatives, as we will see in the proof of the theorem.
If u and v are differentiable functions, then 1. 2.
dv should be selected so that v can be found by antidifferentiating Also, should be simpler to work with than the original integral. !!! Do not forget to consider a variable substitution before using any more advanced technique.
