This is extremely basic but IBP is kind of "the chain rule" for integration. Never say that out loud in lecture but you're allowed to think it if it helps. Substitution is easy and normally quick to check so do that with a few different ideas first. Don't forget to try substitution twice if need be. Don't be afraid to implement multiple methods if need be too. We've all see the integration by parts after a substitution (a real good way to test both methods in one question) Keep up the practice and you'll eventually get an eye for each method

for IBP, let dv = the most complicated part of the integral that you can evaluate, that works 9/10 times
Thanks guys
