Welcome to my Jgrapher 1.0

How to use the grapher?

1.  Select the angle mode. (degrees/radians top right corner).
2.  Select graph mode. (rectangular/polar).
3.  Click-in the equation using the button panels.
4.  Set bounds for x-values. (x-min/x-max).
5.  Set scale. (y/x).
6.  Click draw button.
7.  If graph is invisible (out of bounds) reduce the scale.
8.  If graph is very small increase polar magnifier.
9.  Reduce x-limits to zoom.
