Some computer algebra systems have commands that will draw approximating rectangles and evaluate the sums of their areas, at least if x*i is a left or right endpoint. (For instance, in Maple use leftbox, rightbox, leftsum, and rightsum.) (a) If fsxd 1ysx 2 1 1d, 0 < x < 1, find the left and right sums for n 10, 30, and 50. (b) Illustrate by graphing the rectangles in part (a). (c) Show that the exact area under f lies between 0.780 and 0.791.
