*** Description ***

Equation Grapher is a function plotting program. It allows you to draw 
graphs like y=2x and y=sin(x+10)-cos(3x). It is possible to have up to 13 
graphs plotted at the same time. 

Once you have plotted a function, Equation Grapher automatically finds 
roots, maximum/minimum, intersections, etc.

It can also calculate and view integration area.

You can change the range of the graph, either by using the built in zoom 
functions, or by manually typing in the range values.

If you like, you can copy the graph window and paste it into your word 
processor. Of course, it is possible to save your work and continue at 
another time. A pedagogical help file with descriptive pictures is 
included.




*** Installation ***

Just unzip the files to a new directory/folder and run.
If you want to uninstall the program, simply remove the above 
directory/folder. Nothing else needs to be done.




*** Shareware ***

This is a free demo version of Equation Grapher. It is limited in the way 
that an annoying form is shown for ten seconds every time a graph is 
plotted. Except from that, it includes all the features that are in the 
Professional version.
