Element Conic

JXG.GeometryElement
   ↳ JXG.Curve
         ↳ Conic

This element is used to provide a constructor for a generic conic section uniquely defined by five points.

Defined in: conic.js.
Extends JXG.Curve.

Element Detail
Conic
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "conic".

Possible parent array combinations are:
{JXG.Point|Array} a
{JXG.Point|Array} b
{JXG.Point|Array} c
{JXG.Point|Array} d
{JXG.Point|Array} e

Parent elements are five points.


{Number} a00
{Number} a11
{Number} a22
{Number} a01
{Number} a12
{Number} a22

6 numbers


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create a conic section through the points A, B, C, D, and E.
 var A = board.create('point', [1,5]);
 var B = board.create('point', [1,2]);
 var C = board.create('point', [2,0]);
 var D = board.create('point', [0,0]);
 var E = board.create('point', [-1,5]);
 var conic = board.create('conic',[A,B,C,D,E]);
