| To graph a different function, edit the function expression.
Just highlight the expression and type over it. Variables must be entered as
Wildcard. To input the variable x as a Wildcard, first type Shift+?, then type x.
If a new graph does not automatically appear, try clicking the mouse cursor anywhere in
the graphing window. To zoom on a portion of the graph, first click on the top button on the right side of the graphing window called the Knife. Then use the mouse to box-off the portion of the graph to zoom-in on. To change the graphing window boundaries, edit the values: Left, Right, Top, Bottom. To change the domain of r, edit the values: Minimum, Maximum. To reset the original values, or if an error occurs, just reload the file.
