 * 1) First, we pick some positive integer for N.
 * 2) We now subdivide the interval interval into N equal subintervals.
 * 3) There should be new subintervals after you do step 2. Each of the new subintervals has length
 * 4) Label the endpoints of the new subintervals.
 * 5) In each of the subintervals we pick a number xi and draw a line segment perpendicular to the x-axisfrom the point to a point on the graph.
 * 6) Then construct rectangles which have the line segments as their height and the subintervals as their base.
