- ParametricDerivative[ <Curve> ]
- Returns a new parametric curve given by \left( x(t), \frac{y'(t)}{ x'(t)} \right) .
- Example:
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) = \frac{x²}{4}, and the result is the derivative of that function: f'(x) = \frac{x}{2}.
