MathPlotter with expression Parser

New applet with full runtime expression parser support. Java 1.2+ required. Unfortunately, in order to run this applet, you'll need to tell the Java 2 Plug-in to trust this applet (See how to). Otherwise the internal reflection mechanism of Java won't work for security reasons. For these reasons, future releases will be signed to allow a simpler procedure, here.
</COMMENT> No JDK 1.4 support for APPLET!!

A nice example function to display is f:R->R; x |-> f(x) := 1 / cos(1/x*4). In order to display this function

  1. type its function term
    1 / cos[1/x * 4]
    and confirm with Enter.
  2. Then you should see the graph.
  3. To adjust which part of the graph is shown, either use the arrow buttons, or double-click on the panel and change the range settings, directly. Good settings for f(x) is the range from -10 to 10 for both, x and y values.

Another nice example is cos[2*x]*x.
