- ParametricDerivative[<Curve x=x(t), y=y(t)>]
- Returns a new parametric curve given by
*(x(t), \frac{y'(t)}{ x'(t)})*. **Example:**`ParametricDerivative[Curve[2t, t², t, 0, 10]]`

(which equates to function*f(x)= \frac{x²}{4})*returns the parametric curve*(x(t)=2t,y(t)=t)*(which equates to the derivative of the function*f'(x)= \frac{x}{2}).*
