That's not a quick solution, you omitted details that you should explain at least.
Originally Posted by Krizalid That's not a quick solution, you omitted details that you should explain at least. Ok I owe it at least that much... Now using integration by parts on the second and standard techniques on the first we obtain the antiderivative O...and just because I know you love it Integrating we get That was obviously a stupid joke^...me attempting to be funny
Partial integration is involved. Find another solution which does not involve integration by parts.
Let: Then: Summing the expressions above : And: Thus:
Pretty similar I did. I defined
I got confused with the method shown. here's another: note that Thus,

Here's my solution: Let Substitute In general hence
