Differential and Difference Equations through Computer Experiments

Phaser is a sophisticated program for IBM personal com-
puters, developed atBrown University by the author and some
of his students, which enables usersto experiment with
differential and difference equations and dynamical systems
in an interactive environment using graphics. This book
begins with a brief discussion of the geometric inter-
pretation of differential equations and numerical methods,
and proceeds to guide the student through the use of the
program. To run Phaser, you need an IBM PC, XT, AT, or PS/2
with an IBM Color GRaphics Board (CGB), Enhanced Graphics
Adapter (VGA). A math coprocessor is supported; however, one
is not required for Phaser to run on the above hardware.
