I have studied the fundamental thereom although it was quite some time ago, would you mind explaining how you obtained 4 on the upper limit of integration for Sorry, think I may have just found it: is that the formula?

Yup. The reason I thought you hadn't done the FTC yet was that I assumed you wanted to evaluate this limit in order to evaluate the integral. I guess not.
Alright I got 195/4! Thank you very much redsoxfan you have been most helpful
