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]);
