hi Zeeshan 01

Wow! Where did that come from? Not out of a beginners book of integration, I hope. I couldn't see how to do it, so I used to compute it. It has a far from easy solution as you'll see. Did you just make this one up yourself? That's a hazard with trying that. Not all functions are easily integrable.

Thanks zetafunc. It seems that the limits make all the difference.

Zeeshan 01: After a bit of research I think I can take you through this, but it'll take more than one post. If you would like that please reply. Or you could do like me and use a search engine.
