1. (13 points) Use the limit of a Riemann Sum (i.e. sigma notation and the appropriate summation formulas) to evaluate the net-signed area between the graph of f(0) = 23 – 3 and the interval (0, 2). Let 27 be the right endpoint of the k-th subinterval (where all subintervals have equal width). Give your answer as a single integer or frac- tion, whichever is appropriate. Using any technique other than a limit of a Riemann Sum will earn no...
