My name is Mike Epstein, and I have just graduated from high school. In pre-calculus and calculus, I noticed that my teachers had a hard time demonstrating many implicit expressions. There was no easy way to do it, and there was no software available that didn't cost hundreds of dollars.
So I decided to write SuperGraph to help them out. SuperGraph is a professional-quality implicit (and function) graphing program for Macintosh and Power Macintosh.
If you teach high-school math, SuperGraph can really help you help your students visualize implicit expressions. SuperGraph is shareware; if you use it, registration is $15 (or $300 for a site license).
I hope you will consider trying SuperGraph. It's a free download, and there's no obligation whatsoever. Some additional information is below.
I'll be happy to email you a copy if you ask (via private mail) for one. It's also available through the web page listed below.
SuperGraph is a powerful, easy-to-use, inexpensive program to graph explicit and implicit mathematical functions. Implicit expressions, ones that cannot easily be solved for either x or y, have presented a challenge to visualize. SuperGraph makes that a thing of the past.
For example, SuperGraph can graph complex expressions in two variables like y^2(y-1)-x^2(y^2-1)+2xy^2-x^4=0. And best of all, it's only $15 (payable through Kagi Shareware or directly to the author at 90 Maple Drive, Great Neck, NY 11021).
SuperGraph differs from Apple's Graphing Calculator in its flexibility and customizability when dealing with implicit expressions (which Graphing Calculator does not directly support) and in its ability to run on 680x0 (non-PowerPC) Macintosh computers.
SuperGraph is especially suited to demonstrating various implicit expressions and techniques of sketching them in a classroom situation.
SuperGraph requires either a PowerPC processor or a 68020, 68030 or 68040 with math coprocessor (FPU).
