a similar problem is done here. i am sure you can find this exact problem lying around the forum somewhere

there is also a solution using complex numbers if you are interested. it was posted by Kriz, i am sure i can find it if need be - Jul 6th 2008, 05:28 PMJhevon

if you have to do it by parts, then the post i was talking about wont help. by parts wasn't used at all. it was a bit of complex analysis

You're right, it's quite likely not the best way to solve it, but unfortunately the problem states I have to do it with integration by parts. I'll try it harder (Speechless).
