F(x) = $\displaystyle \int _1\,^x\! $ $\displaystyle sin\pi t $ dt

I know that F'(x) = f(x), but what is f(x) here? do I just sub x into $\displaystyle sin\pi t $?

Your writting is quite hard to read, better you to improve it.

Besides, it's a simple application of the FTC. - Jan 12th 2010, 05:23 PMskeeter
