*** Description ***

Equation Grapher is a tool for plotting and analyzing functions.
It lets you draw graphs like y=2x and y=sin(x+10)-cos(3x).
You can plot up to 12 graphs in different colors at the same time.
Once you have plotted a function, Equation Grapher automatically
finds roots, maximum/minimum, intersections, etc., and can also
calculate and view integration area. 

Equation Grapher also features several zoom functions, a background
grid, the ability to change the text of the x- and y-axis, file
saving (function file or BMP/GIF), the ability to print graphs 
directly or copy them to the Clipboard (to paste them into your
word processor), and more. Angles can be in either degrees or
radians. Besides trigonometry functions, random numbers and
logarithms, Equation Grapher also has the d/dx derivative function.
Constants like pi and e are included as well. A pedagogical help
file / tutorial teaches you how to use the program.
