1. The problem statement, all variables and given/known data

Express the integral as a limit of Riemann sums. Do not evaluate the limit.

2. Relevant equations

$$\int_0^{2\pi} x^{2}sin(x)\,dx$$

3. The attempt at a solution

I really don't know where to start...any help getting me started would be highly appreciated!

but seriously just expressing any integral is probably much simpler than you are thinking, all you have to do is basically write down the definition of a Riemann sum here is a better link:

(first equation on page, just substitute your function in)
