There are many graph-drawing programs, but doing it well is harder than it may seem. The traditional approach is to restrict users to considering only explicit functions of the form y=f(x) and to graph them by “joining the dots”, but this approach can give inaccurate results and is unnecessarily limiting. Students of algebra should be free to explore the broader class of relations, including inequalities like (x^2+y^2)^2<12*(x^2-y^2).

EDGE a graphing engine that can quickly and accurately graph a broad range of algebraic relations. Additionally it can identify and display regions where the relation is undefined. The engine has been designed specifically for embedding within handheld calculators, using efficient algorithms and compact data structures that perform well within the processor and memory constraints of a low-power device.
