Unlike in mid-point and trapezoidal rules, here n is required to be even because we are going to
approximate the curve with parabolic arcs where each arc passes through three consecutive points, i.e.
two of the subintervals, so if n is even we could approximate the whole curve with parabolas.
Now, let us compute the area bounded by the standard parabola y ax bx c
