- ClosestPoint[ <Path>, <Point> ]
- Returns a new point on a path which is the closest to a selected point.
Note: For Functions, this command now uses closest point (rather than vertical point). This works best for polynomials; for other functions the numerical algorithm is less stable.
Following text is about a feature that is supported only in GeoGebra 5.0.
Note: From GeoGebra 5, these syntaxes will work as well: ClosestPoint[ <Region>, <Point> ], ClosestPoint[ <Line>, <Line> ] |
