Let f(x) = x
Use a Riemann sum with four subintervals of equal length (n = 4) to approximate the area of R (under the graph of f on the interval [0, 2]). Choose the representative points to be the left end points of the subintervals.
__________ sq units
Repeat previous part with eight subintervals of equal length (n = 8).
__________ sq units
Compare the approximations obtained in previous parts with the exact area (2 sq units). Do the approximations improve with larger n?
