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


Left-endpoint Riemann sum:

Notice that there will be rectangles squeezed into a unit interval. This will be a very small , and a very good approximation of the area under the curve.

ACTUAL AREA: If you cannot visualize the familiar geometric shape that is formed when you graph on , then sketch a graph.
