How to Use this Site

This site uses the Webeq Math Viewer applet to render the interactive mathematical expressions. To use this site effectively we recommend.

1. Enable Java in your browser. This site will not operate without it.
2. Use Internet Explorer as your browser, preferably version 5 or higher. The applets are optimized for use with Internet Explorer 5. In addition there are two bugs involved with the use of Netscape Navigator. One is the well known bug that in some versions of Navigator resizing windows is not done correctly. This bug can be fixed by reloading the page. The second and more serious bug involves an interaction between the Webeq applet and Navigator when using pop-up windows. This bug causes Netscape Navigator to crash. A Navigator friendly version of this site is in the pipeline.
3. Install the Webeq Math Viewer applet as a plug in. The option to do this will be given to you automatically when you go to the home page. This will dramatically speed up the operation of this site.

Interactive Equations

Interactivity on this site is represented by a pale blue background. Wherever you see this background there is something within the blue area that is clickable. This may be a pop-up window or it may be an interactive equation. (Equations which are not interactive are coloured white). For interactive equations the actual active area will be indicated by a highlighted background when you roll the mouse over the area.

Here is a simple example.

Dynamic Graphs

This website uses and supports the following dynamic graphing technologies.

Winplot

A freeware PC graphing program. It can be obtained from Peanut Software.

Geometers Sketchpad

A dynamic geometry package. The full version and a demo version can be obtained from Key Curriculum Press.

Java Applets

The LiveGraphics3D and Java Sketchpad applets. These require no installation.
