Functions That Fool Graphing Calculators

The purpose of this page is to collect a number of examples of functions whose graphs are rendered incorrectly on some type of graphing calculator. This page is not meant to be an attack on the use of graphing calculators in education, but rather a contribution to the correct use of graphing calculators in education. I personally believe that new technologies should be used in education and have made a more detailed statement describing my viewpoint on how to incorporate this new technology.


The Graphs

This page is somewhat graphic intensive.

Generating the Pictures

The pictures were generated using a Mathematica package which emulates a graphing calculator.

Why This is Important

My statement on technology in education.
