Graph
Graph is a simple graphing utility. It graphs up to five functions.
Slinky
Slinky solves and graphs the solutions to initial value problems. Given a set of differential equations with up to 10 variables, together with initial conditions, it will draw the solutions curves. If the system has only one dependent variable, Slinky offers the slope field.
Slinkyplus
SlinkyPlus, like Slinky, solves and graphs the solutions to initial value problems. It can also show solutions for higher order systems of equations. If the system has exactly two dependent variables, Slinkyplus offers the phase plane.
Graphplus
Graphplus is a three-dimensional graphing utility currently. It graphs functions of two variables over rectangular domains in five ways: as a wire frame, as a three-dee wire frame (3D glasses required), as a contour map, as a density plot, and as a reflecting surface. The reflecting surface (called dunes) is particularly interesting. It is unlike any program we know in that it shows not just a small portion of the surface, but all that the eye can see. It is, however, a bit slow.
