Class Detail
Normal(o,p, p)
A normal is a line through a given point on a element of type line, circle, curve, or turtle and orthogonal to that object.
// Create a normal to a circle.
var p1 = board.create('point', [2.0, 2.0]);
var p2 = board.create('point', [3.0, 2.0]);
var c1 = board.create('circle', [p1, p2]);

var norm1 = board.create('normal', [c1, p2]);

				
				
				
				
					
						
Parameters:
{JXG.Line|JXG.Circle|JXG.Curve|JXG.Turtle_JXG.Point} o,p
The constructed line contains p which lies on the object and is orthogonal to the tangent to the object in the given point.
{Glider} p
Works like above, however the object is given by Glider#slideObject.
Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Field Detail
{JXG.Point} point
A helper point used to create a normal to a JXG.Line object. For normals to circles or curves this element is undefined.
