Regardless of the confusion, there is a gaping error in the OP, where you say that:

and I think you mean:

- the 2 isn't cubed. This should help with whatever it is you are trying to solve. I don't know whether you're trying to**differentiate**or**integrate**still, so please specify - copy the exact wording of the question. - March 30th 2011, 09:54 AMdjnorris2000
Thanks Quacky, I meant differentiate all along. That's what I get for browsing ahead in the book and posting when I'm brain dead from work.

I figured I'd be making a simple mistake in there and now that you've pointed that out I'm arriving at the right answer.
