Reviewer Comments:

This exercise uses trial-and-error (plus a computerized graphing tool) to estimate the solution to an optimization problem, namely finding the largest rectangle that can be inscribed under a parabola. This approach, though non-analytic, has a lot of intuitive appeal to it. The student who follows all the instructions will come to see why there should be a largest rectangle and what determines its size.
