I need a java applet or a javascript program to draw a graph of an entered mathematical function of x. For example sin(x), 1/x or x^2 + tan(3+x)
The program must be able to run under Windows Explorer, 6, 7 or 8, and does not require Canvas.
*Minimum functions of the program.

The program should have the ability to change the mazimum and minimum x values, the ability to show a grid, the ability to select ranges, and the possibility to show the co-ordinates on the graph line.
*Extra functions
*Any extra functionality that can be added will be considered, such as the ability to display 2 or more equations on the graph, the ability to zoom etc
