Sample G&G Screen Shots
A Cartesian plot showing how
adding successive terms of the Fourier
series of a square wave improves the approximation. Each plot
can be easily
made visible or invisible for demonstration purposes
using the
"Visible" check box.
A graph on polar coordinates, plotting the radius
as a function of t. You can
specify
the range of t to be displayed (for example, from 0 to 2pi in
increments of 0.01). Note the use of the K-Slider to systematically
vary
the plot. This example shows the effect of changing the frequency
of a sine function on its polar representation.
A parametric graph, in which you specify x and y as
functions of t.
This graph shows the relationship of the sine and cosine functions
to a circle of radius 1. (The variable k is set to 1.5 in this
screenshot.)
A sample scatterplot and regression,
showing the use of the Edit|Data,
Edit|Scatterplot, and Edit|Regression commands.
Data can be entered directly or read from files. The Regression
command allows you to calculate (and plot) a variety of types of regressions,
as well as save residuals and predicted values.
Our own GraphinDance!
This was done completely with formulas (no cheating) in a
parametric graph. Contact us and ask for the
GraphinDance
status file (readable only with the registered version) to see
the complete set of graphs that create our dancer when
animated with the K-Slider.
