Integration By Parts??? 1. The problem statement, all variables and given/known data int.arctan(2x)dx 2. Relevant equations Integration By Parts 3. The attempt at a solution In the attached image is the original problem with the ansewer I came up with using integration by parts and then a v=sub. later in the problem I did not want to post additional steps because it turned out to be a longer problem than I thought Just curious if someone could confirm my ansewer and if it is incorrect I will post the work to help see where I messed up. thanks a ton.
