*** Description ***

This is a package of two integrated programs: Equation Grapher and Regression Analyzer.

Equation Grapher is a function plotting and analyzing program. It allows you to draw
graphs like y=2x and y=sin(x+10)-cos(x). It is possible to have up to 12 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. 

Regression Analyzer is an analyzing and curvefinding program for statistical data. The
program handles the usual regression models such as linear, logarithmic, exponential
and power etc. It also supports polynomial models and multiple regressions. To find the
best model for your data, simply use the auto function that finds the best model
instantly. In the log window, next to the graph you will get all necessary information,
such as equation and correlation. 

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.
