- CurvatureVector[ <Point>, <Function> ]
- Yields the curvature vector of the function in the given point.
- Example:
CurvatureVector[(0, 0), x^2]yields vector (0, 2).
- CurvatureVector[ <Point>, <Curve> ]
- Yields the curvature vector of the curve in the given point.
- Example:
CurvatureVector[(0, 0), Curve[cos(t), sin(2t), t, 0, π]]yields vector (0, 0).

Following text is about a feature that is supported only in GeoGebra 5.0.
Note: From GeoGebra 5, this command will work with conics as well.
