- ParametricDerivative( <Curve> )
- Returns a new parametric curve given by .
ParametricDerivative(Curve(2t, t², t, 0, 10))returns the parametric curve (x(t) = 2t, y(t) = t). The curve given as argument to the command is the function f(x) = , and the result is the derivative of that function: f'(x) = .
