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.


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.
