This is what I did.

This is what I SHOULD have done.
Then split up the 2/(9-x^2)
Stupid ERRORS!

Really I should have just done partial fractions from the start.

EDIT: fixed it, I still had it wrong.

I actually looked at that and thought it was right and was thinking why didnt I do it this short way!?!

Anyone get -1/3 ( log e l 3 - x l + log e l 3+x l ) ?

Wasn't it -1/3 (2* log e l 3 - x l + log e l 3+x l ) ??
