_{Lower sum calculator. The total area of the inscribed rectangles is the lower sum, and the total area of the circumscribed rectangles is the upper sum . By taking more rectangles, you get a better approximation. In the limit, as the number of rectangles increases "to infinity", the upper and lower sums converge to a single value, which is the area under the curve . }
