    have you tried integration by parts ?

    I don't think you can using 'standard' functions.

    There's no "nice" function that will be a solution to this integral. You need to write it out as a series and integrate term by term. Your solution will be in series form

    Hmm, then I must have done something wrong earlier. It's part of a larger integration by parts problem, and we haven't learned series yet.

    Lol, never mind. I can solve this with U-sub.
