Trigonometric mathplets


2015 update

The Internet has evolved since the year 2000. These applets have not.
It's becoming more and more difficult to run java applets (due to security reasons as well as a lacking support for java plug-ins in some browsers (Chrome)). I have therefore recompiled these activities into one single stand-alone java application that you can download and run on your computer.

TrigActivities.jar

If you're on a Mac, don't forget to hold the ctrl-key down while you click the file to be able to run it.
If you use a Linux machine, don't forget to set the executable rights.
