# CurvatureVector Command

From GeoGebra Manual

- 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)*.

- CurvatureVector( <Point>, <Object> )
- Yields the curvature vector of the object (function, curve, conic) in the given point.
**Examples:**`CurvatureVector((0, 0), x^2)`

yields vector*(0, 2)*`CurvatureVector((0, 0), Curve(cos(t), sin(2t), t, 0, π))`

yields vector*(0, 0)*`CurvatureVector((-1, 0), Conic({1, 1, 1, 2, 2, 3}))`

yields vector*(0, -2)*
