This interactive site provides teaching and learning resources you can use to get the most from your course

The Boston University Differential Equations Project Site: This site provides teaching and learning resources by the authors of the textbook.

Selected Animations (QuickTime format): Animations by Professor Devaney used in the Boston University Differential Equations course.

ODE software from Rice University. This does the same sort of direction field and phase portrait plots as Maple and the CD, but in a Java applet. So you can run it from any computer with a web browser and Java.

Accessing Software (Maple)   ; not installed in your laptop. Maple is not required for this course, but it is available in case you want to experiment       Differential Equations with Maple.

Maple commands to plot and solve Differential Equations: Soon!

·  "ODE phase plane plotter" (Java-applets), by Scott Herod

·  "ODE Phase Portraits 1.1" by Richard Mansfield and Frits Beukers;
If you use it for first order DEQs, x is the independent variable; y is the dependent variable: Set x '=1.
