This small collection of web pages discusses a nice extension to Gaussian quadrature that does not seem to be discussed in a large number of numerical analysis texts. It is of importance because it is apparently the method used by TI calculators, a fact that is sure to get the attention of students. The pages give some nice experimental exercises to help students see the need to transform functions from one interval to a standard one. It also uses a Java applet effectively to show graphically the way that Gauss-Kronrod Integration uses only half the nodes used by Gaussian quadrature.
