lim as n goes to infinity of (pi/n) (sin(pi/n) + sin(2pi/n) + sin(3pi/n) +...+ sin(npi/n)) =

I.) lim as n goes to infinity sigma (n and k=1) of pi/n sin(kpi/n)

II.) Definite integral from 0 to pi of sin(x)dx

III.) 2

A.) I only

B.) II only

C.) III only

D.) II and III only

E.) I, II, and III

Wow, I am really lost on this one, please help!

- details (still need help) -
