Extends JXG.Curve.
This element is used to provide a constructor for an ellipse. An ellipse is given by two points (the foci) and a third point on the the ellipse or the length of the major axis.
Defined in: Conic.js.

Class Detail
Ellipse(point1,point2,point3, point1,point2,number)
// Create an Ellipse by three points
var A = board.create('point', [-1,4]);
var B = board.create('point', [-1,-4]);
var C = board.create('point', [1,1]);
var el = board.create('ellipse',[A,B,C]);

				
				
				
				
					
						
Parameters:
{JXG.Point|array_JXG.Point|array_JXG.Point|array} point1,point2,point3
Parent elements can be three elements either of type JXG.Point or array of numbers describing the coordinates of a point. In the latter case the point will be constructed automatically as a fixed invisible point.
{JXG.Point|array_JXG.Point|array_number|function} point1,point2,number
Parent elements can be two elements either of type JXG.Point or array of numbers describing the coordinates of a point. The third parameter is a number/function which defines the length of the major axis Optional parameters four and five are numbers which define the curve length (e.g. start/end). Default values are -pi and pi.
Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
