Class Detail
PerpendicularPoint(p,l)
A perpendicular point is given by a point and a line. It is determined by projecting the given point
orthogonal onto the given line. This element should be used in GEONExTReader only. All other applications should
use orthogonal projection Orthogonalprojection.
- Parameters:
- {JXG.Line_JXG.Point} p,l
- The constructed point is the orthogonal projection of p onto l.
- Throws:
- {Error}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
var p1 = board.create('point', [0.0, 4.0]); var p2 = board.create('point', [6.0, 1.0]); var l1 = board.create('line', [p1, p2]); var p3 = board.create('point', [3.0, 3.0]); var pp1 = board.create('perpendicularpoint', [p3, l1]);
