Hi,

I am revising on Solids of revolution and I am stuck on integrating a particular function. I have been given examples examples of similar variations but not this one, so I have been stuck all.

How would you integrate functions in this form:

I have been shown when the top x is a number such as 2 or 1.

Thanks. Sorry I can't type maths yet.
