3-136.

Write a Riemann sum to estimate the area under the cuve for . Then compute the actual area geometrically and calculate the percent error.

APPROXIMATE AREA:

Left-endpoint Riemann sum:

Notice that there will be

ACTUAL AREA: If you cannot visualize the familiar geometric shape that is formed when you graph on
