I introduce estimating the Area in a Plane using rectangles. I then expand on that concept using summation notation and limits at n approached infinity to find the exact area bound by a function and the x-axis within a closed interval. This video includes examples of estimating the lower and upper sums with rectangles and finding exact area with infinite sums.
When I wrote the formula for the Upper Sum, the upper bound of the sigma notation should be n, not Infiniti. Find free review test, useful notes and more at http://www.mathplane.com
