Graphulator With Numerical Calculus

Graphulator is a numerical graphing calculator for 2 or 3 variable equations. Plot both functions and non-functions. Includes data output! Now includes numerical calculus.

Graphulator boasts being the only calculator which can perform calculus on non-functions numerically (equations which cannot be reduced to a function).

Graphulator boasts being the only numerical calculator which can plot three variable non-functions.
(Equations of the form f(xyz) = f(xyz)).

If you believe either of these claims to be untrue, let us know (contact@Graphulator.com).
