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.
Use Pi for pi; for example, sin(Pi/2 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.

Zooming

You can change the scale of your picture quickly with "Zoom In",
"Zoom Out" and "Zoom to Box". The first two zoom in or out around
the center of the graph. If you click and drag on the graphing
window, you can draw out a box, and Zoom To Box will zoom
in to make that box fill the whole window.
