About the Java applet.

Images in Dave’s Short Trig Course are illustrated with a Java applet. If your browser is Java-enabled, you can drag the points around in the diagrams and the diagram will adjust itself. The applet also allows you to lift a diagram off the web page into its own floating window. For details, see About the applet.

Note that some web browsers do not allow printers to print images created by Java applets. You may still be able to print the images if turn off Java in your browser, and the plain images should appear that can be printed.
