The trick I always use is, let dv be the function that has the cleanest antiderivative such that the order does not increase (unless using the "invisible dv") I love this part of Calculus 2. A nice taxonomy of integration tricks, and integration by parts has its own corner cases such as using "I" and the "invisible dv" where dv = dx. That’s really interesting.
