Class Detail
Intersection(el1,el2,i)
An intersection point is a point which lives on two Lines or Circles or one Line and one Circle at the same time, i.e. an intersection point of the two elements.
// Create an intersection point of circle and line
var p1 = board.create('point', [2.0, 2.0]);
var c1 = board.create('circle', [p1, 2.0]);

var p2 = board.create('point', [2.0, 2.0]);
var p3 = board.create('point', [2.0, 2.0]);
var l1 = board.create('line', [p2, p3]);

var i = board.create('intersection', [c1, l1, 0]);

				
				
				
				
					
						
Parameters:
{JXG.Line|JXG.Circle_JXG.Line|JXG.Circle_Number} el1,el2,i
The result will be a intersection point on el1 and el2. i determines the intersection point if two points are available:
  • i==0: use the positive square root,
  • i==1: use the negative square root.
Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
