Write a Riemann sum to estimate for using left endpoint (or other) rectangles. Then calculate the area for , , and rectangles. Which is most accurate and why?

Refer to hints in problem 3-177 for further guidance about computing a left-endpoint Riemann sum.

Without a calculator, it is more time consuming to compute a sum with terms than with terms. What is the benefit of using terms?
