(1 point) Consider the function f (ac) = 1. In this problem you will calculate - 1) da by using the definition [ f(z) da = lim The summation inside the brackets is R, which is the Riemann sum where the sample points are chosen to be the right-hand endpoints of each sub-interval. Calculate Rn for f(a) = - 1 on the interval [0, 2] and write your answer as a function of n without any summation signs. You will need the summation formulas in Section 5 of your textbook. Rn = lim Rn = n-700
