Formula Graphing Applets

This page demonstrates one program from the package, "graphing", of Java classes I am developing to use for graphing mathematical functions in educational demonstrations. This page shows a general purpose graphing tool. Other pages show subclasses of this program which include extra features to illustrate concepts in integration and differentiation.

If you can see this, it means you do not have a browser that can view Java programs.

Instructions:

Adding Functions: Press "Add Function" button and type in a formula to be graphed in standard mathematical notation (eg "e^(-x/10)sin(x)"). The only variable the formula can use is x. You can add as many functions as you like, and "Delete Function" deletes the last one you entered.
Rescaling: This brings up a panel which you can use to edit the scale of the graph. The x variable runs between xMin and xMax, and the y values run between yMin and yMax. Use xScale and yScale to set the spacing of tick marks on the axes. If xScale or yScale is zero, the graph will have no tickmarks on that axis.

Please play with the program here, and see what it can do.It's still under development; so go ahead and try to break it, and let me know if you can!

If you like my program and you want to use it in your pages, just include the tag

<applet height=350 width=350 codebase="http://www.math.unl.edu/~jorr/java" code="graphing/applets/Grapher.class"> </applet> in your web pages and you'll get what you see here!

If you have suggestions for changes, developments, or extensions of this program please mail me. Please mail me with bug reports too!
