A. Find the exact value: $\int_0^{2\pi}\,\sin(\theta)\,d\theta =$

B. Find the MID(1) and MID(2) estimates for the integral:
MID(1) =
MID(2) =

C. Sketch MID(1) and MID(2) for this integral. Be sure that you can explain, using your sketch(es) why your results in A and B are related as they are.
What would you get if you found MID(3)?
How about MID(n)?
