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:
-
- Parent elements are five points.
-
- numbers (a_00,a_11,a_22,a_01,a_12,a_22)
- 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]);
