Implicit Curves: Executable or Text Version
Usually, curves are drawn from an EXPLICIT formula such as y=sin(x) , where y is on one side of the equals sign, and all the stuff to do with x is one the other side. An IMPLICIT function is of the form F(x,y)=0. Most formulae cannot be written explicitly, but this very simple program allows you to see what something like x*x + y*y +sin(xy) 16 =0 looks like, for example.
