Inverse Graphing Calculator

Hi everyone, new to the forums I'm a math grad student from Ohio State University..

Anyway, the reason I came was to mention a new project I've launched: The Inverse Graphing Calculator.

Unlike a conventional graphing calculator, where you enter an equation and get a graph, this one lets you specify the graph you want, and it generates the *equation*.

In the current form, you can specify the graph using Roman letters. Thus you can get equations whose graphs spell things out, like "Hello World" or "Will you marry me" or whatever you like

Here it is: The Inverse Graphing Calculator

Re: Inverse Graphing Calculator

Extremely nice. When I saw the title I was expecting something like a regression calculator (which would be useful, if mundane); this is cool and reminds me of the various cute Matiyasevich polynomials, though they are usually of the form a^2 + b^2 + ... = 0 rather than abc... = 0, since you want lines rather than discrete points.
