Consider the function f(x) = = •2 In this problem you will calculate 1²₁-²³²3 (- 5) dx by using the definition 0 ob n ['s f(x) dx = lim Σ f(xi) (2₁) 42 n→[infinity] _i=] The summation inside the brackets is Rn which is the Riemann sum where the sample points are chosen to be the right-hand endpoints of each sub-interval. Calculate x² I'N for J) - on the interval [u, 4] and write your answer as a function of without any summation signs. Rn = lim Rn = n→[infinity] Note: You can earn partial credit on this problem. - ² – 5.
