The integral integral_3^9 x^2 dx can be calculated approximately by the left sum method (finding the area of multiple rectangles whose top left corners lie on the curve). Figure 1 shows such an approximation with 4 rectangles. Write a MATLAB function to calculate the truncation error caused by the left sum method for integral_3^9 x^2 dx. Your function should meet the following requirements: It should be named NumericalInt It should have the number of rectangles as the sole input argument....
