What to notice
Be sure that you can see the red rectangles by checking the box 'Estimated by Rectangles'. Then move the button for n and notice that as n increases, the number of rectangles increases. Notice that the area reported in red as the Rectangle Sum gets closer to the actual area as the number of rectangles gets larger.
