Graphically show the difference to integrating between points a and b on the following graph by the trapezoidal rule, the Simpson's 1/3 rule, and the Simpson's 3/8 rule.

	Note the use of 2 points (1st order equation) with the trapezoidal ruld, 3 points (2nd order equation) with Simpson's 1/3 rule, and 4 points (a 3rd order equation) with  Simpson's 3/8 rule.
