Functions of two variables appear frequently in engineering studies. Students have particular difficulties in understanding how the graphs of these functions are. This paper presents a sequential mode ...

Graphically demonstrates that the shape of the sine, cosine, and tangent functions are derived from geometric relationships on the unit circle. This program was conceived as part of a class project in ...

In a 1995 paper on the chromatic symmetric function, former MIT mathematician Dr. Richard P. Stanley stated that there was no known graph that was not contractible into a claw pattern and whose ...
