In this problem you will calculate the area between f(x) = x^2 and the x-axis over the interval [1, 10] using a limit of right-endpoint Riemann sums: Area = lim_{n??} (?_{k=1}^n f(x_k)?x). Express the following quantities in terms of n, the number of rectangles in the Riemann sum, and k, the index for the rectangles in the Riemann sum. a. We start by subdividing [1, 10] into n equal width subintervals [x_0, x_1], [x_1, x_2], ..., [x_{n-1}, x_n] each of width ?x. Express the width of each subinterval ?x in terms of the number of subintervals n. ?x = 9/n b. Find the right endpoints x_1, x_2, x_3 of the first, second, and third subintervals [x_0, x_1], [x_1, x_2], [x_2, x_3] and express your answers in terms of n. x_1, x_2, x_3 = (Enter a comma separated list.) c. Find a general expression for the right endpoint x_k of the k^{th} subinterval [x_{k-1}, x_k], where 1 ? k ? n. Express your answer in terms of k and n. x_k = d.
