Write a MATLAB program to compute the Left Riemann sum and Right Riemann sum and use it to evaluate the following integral: Integar 3 0 x2dx
A) Using the Left Riemann sum and Right Riemann sums compute the integral for 5,10,50,100, 500 points, plot the approximate integral results vs the number of points (included the exact solution on the plot).
B) Are the Left Riemann sum and Right Riemann sum over- or under-estimates for this problem?
C) Will the answer to lb always hold? Discuss.
