Gauss-Kronrod integration is an adaptation of Gaussian quadrature used on some graphing calculators, in particular the Texas Instruments graphing calculators where it is called fnInt. This mathlet outlines the mathematical computations involved and visually demonstrates the process the calculator uses to evaluate the integral. Visualization highlights possible shortcomings of the method. Examples are suggested in the mathlet for exploration of the method; an example of a troublesome integral with a work-around is included.
