Ah, well if you're using u-substitution it's especially important to specify the unit of integration at the end of your expression. The above confusion is evidence of what can go wrong when this isn't specified.

And off the top of my head, I think changing it to sec^2 would be a good idea, it might allow you to express the whole fraction as some form of sin^2 on cos^2 or vice versa. - Sep 6th 2009, 09:10 AMANDS!
