Estimate the area between the graph of the function f and the interval [a, b]. Use an approximation scheme with n rectangles similar to our treatment of f(x) = x in this section. If your calculating utility will perform automatic summations, estimate the specified area using n = 10, 50, and 100 rectangles. Otherwise, estimate this area using n = 2, 5, and 10 rectangles. 1. f(x) = Jx; [a, b] = [0, 1] %3D 2. f(x) = 1 ; [a, b] = [0, 1] | x +1
