I have found a 25.00 3D grapher that will produce beautiful graphs which can be imported in GeoGebra as bmp files.

This is absoultely the most versatile software for graphing that I have. It does things with parameters u and v, and even t so that things can be animated. It permits a wide variety of outputs, viewable from all angles and perspectives.
It is remarkable- i can't recommend it enough.

The TI 89 is a great calculator. GeoGebra is capable of doing many of the same things. Couple this with Java Graphers, and you have computer resources that completely cover the capabilities, and then some.

These graphers can be used online or installed to your computer. They are powerful indeed, and they are free.
I especially like the 3D grapher- it renders a wide variety of surfaces in natural format.

I downloaded the 3D Grapher from romanlab. I had used it before, and forgotten all about it.

I am a special ed teacher who is developing a Moodle course for basic geometry and I am using Geogebra as an interactive tool for myself and the students. I am learning how to create interactive worksheets for the students and I want they to be able to create their own interactive files to demonstrate geometry skills. The Moodle is at www.lpvec.net/moodle1 now, but we are adding more databases and will have to change the domain name, which I will post as soon as it is set up.
