So it seems like zero, bus this feels kind of wrong to me. Besides, computer software assumes that integral diverges.

What should I do?

Couple of things:

1. is undefined. It's like dividing by zero: not allowed.

2. Your integral most definitely diverges on the positive end. Examining the integral

you see that it diverges. I'd have to think a bit more about what happens at the lower limit. - Mar 10th 2011, 10:23 AMPranas
