pplane8 is an interactive tool for studying planar autonomous systems of differential equations. When pplane8 is executed, a pplane8 Setup window is opened. The user may enter the differential equation and specify a display window using the interactive controls in the Setup window. Up to 4 parameters may also be specified. In addition the user is give a choice of the type of field displayed and the number of field points.
