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.
