Fermat cubic

Fermat cubic

In geometry, the Fermat cubic, named after Pierre de Fermat, is a surface defined by: x^3 + y^3 + z^3 = 1.

Methods of algebraic geometry provide the following parametrization of Fermat's cubic:: x(s,t) = {3 t - {1over 3} (s^2 + s t + t^2)^2 over t (s^2 + s t + t^2) - 3}

: y(s,t) = {3 s + 3 t + {1over 3} (s^2 + s t + t^2)^2 over t (s^2 + s t + t^2) - 3}

: z(s,t) = {-3 - (s^2 + s t + t^2) (s + t) over t (s^2 + s t + t^2) - 3}.
