Just out of curiosity does anyone know who first described a circle in algebriac terms? ie: $\displaystyle (x-h)^2+(y-k)^2=r^2$I'm being asked to give a mathematical decription of a circle.

Probably either Rene Descrates or, my hero, Pierre Fermat.

I say this because they were the first to invent the idea of analytic geometry.
