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.
See new Java web start application with full runtime expression
parser support, which is automatically available offline (most comfort).
See the old applet with smaller memory foot-print
(but limited functionality) for earlier Java 1.0 versions supported in most browsers.
A nice example function to display is f:R->R; x |-> f(x) := 1 / cos(1/x*4).
In order to display this function
type its function term 1 / cos[1/x * 4]
and confirm with Enter.
Then you should see the graph.
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.
