Phaser is a sophisticated program for IBM personal com-puters, developed atBrown University by the author and someof his students, which enables usersto experiment withdifferential and difference equations and dynamical systemsin an interactive environment using graphics. This bookbegins 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 theprogram. To run Phaser, you need an IBM PC, XT, AT, or PS/2with an IBM Color GRaphics Board (CGB), Enhanced GraphicsAdapter (VGA). A math coprocessor is supported; however, oneis not required for Phaser to run on the above hardware.

The subject of differential and difference equations is an old and much-honored chapter in science, one which germinated in applied fields such as celestial mechanics, nonlinear oscillations, and fluid dynamics. In recent years, due primarily to the proliferation of computers, dynamical systems has once more turned to its roots in applications with perhaps a more mature look. Many of the available books and expository narratives either require extensive mathematical preparation, or are not designed to be used as textbooks. The authors have filled this void with the present book.
