We will look at a way to find the area under a curve. One way to do this is to divide the area into rectangles. You can investigate different functions and move the slider for n to change the number of rectangles. We will look at two ways of getting our rectangles, upper rectangles and lower rectangles. You can move points A and B along the x-axis to change the boundaries for the interval.
