I didn't check through your integration, but when you have an improper integral , just compute the limit

Are you familiar with improper integrals? - Jul 25th 2010, 06:42 PMracewithferrari
After solving it, the answer come to ∞. Right?

note that it is rather easy to show that diverges. - Jul 26th 2010, 02:34 AMracewithferrari
I did nothing wrong. I combined num and dem. The sqrt sign is on the top only.
