ParametricDerivative Command
From GeoGebra Manual
This page is about a feature that is supported only in GeoGebra 4.2. |
- ParametricDerivative[<Curve x=x(t), y=y(t)>]
- Returns a new parametric curve given by \left( x(t), \frac{y'(t)}{ x'(t)} \right) .
- Example:
ParametricDerivative[Curve[2t, t², t, 0, 10]]
(the curve 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}).
