Mathlets: JavaTM Applets for Math Explorations

Written by Tom Leathrum

Notes

Another big update, although this still uses Java5 code -- I have added to all of the graphing applets the ability to change the colors of the graphed items. I still have not had a chance to update the source code pages.
I have upgraded the applets to use the features of Java5, especially the new generic classes. This means that, in order to run the applets, you will need a Java5-compatible runtime/plug-in (version 1.5 or later) for your browser. I have not yet had a chance to update the source code page, but there will be many changes there, as well. The Addison-Wesley materials still use the older Java2-compatible versions (use runtime-plug-in version 1.3 or later with these).
The particularly intrepid user may also wish to read the source code for some of these applets.
The Limits applet and the exploration of Exponential Functions and Their Derivatives appear in the January 2001 issue of the Journal of Online Mathematics and its Applications (JOMA), published online under the auspices of the Mathematics Association of America (MAA). Judy Holdener of Kenyon College wrote a review of my materials in the second issue. Since then, I have been working on a series of articles in the Developers Area of JOMA, under the title "Writing Mathlets: A Call to Working Math Professionals" ( part 1, part 2, and part 3 available so far).
I have entered into a publication agreement with Addison-Wesley, which includes a pretty substantial subset of the Mathlets package. By the terms of the publication agreement, though, the content of these Web pages will not be seriously affected by the publication -- I have altered the copyright notifications to include the Addison-Wesley copyright on their materials, but I will still be able to maintain and further develop the materials here.
The Latest Changes:
The applets in the Mathlets package are designed to work in all current browsers using the Java Plug-In version 1.3 or later. The applets have been tested in Netscape version 7.x, Microsoft Internet Explorer version 6.x, and Mozilla versions 1.5 and later, with Java Plug-In version 1.4. All previous issues, involving older versions of the browsers and Plug-In, no longer apply. Look instead for new issues....
