I'm working from a book and trying to integrate , unfortunately I always arrive at the wrong answer. Can anyone point out where I'm going wrong with this working?
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.
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.
