1. The problem statement, all variables and given/known data Hey guys, I'm trying to teach myself how to integrate an indefinite integral. I just am wondering what you can do with something like this: 2. Relevant equations [tex]\int[/tex] 15/(3x+1) dx 3. The attempt at a solution I'm trying to figure out how to go backwards, but I don't see what terms, when derived, give you 15/3x+1 dx. Does anyone know a good way to quickly solve these sorts of problems?
