## 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.
