- 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> ]
- Returns a new point on the region which is the closest to a selected point.
- ClosestPoint[ <Line>, <Line> ]
- Returns a new point on the first line which is the closest to the second line.
- Note:If the two lines are intersecting
ClosestPoint[ <Line>, <Line> ]
yields 0.
