Class Conic
JXG.GeometryElement
↳ JXG.Curve
↳ Conic
This element is used to provide a constructor for a generic conic section uniquely defined by five points or a conic defined by the coefficients of the equation
Ax2+ Bxy+Cy2 + Dx + Ey + F = 0
. Then the parameters are as follows:board.create('conic', [A, C, F, B/2, D/2, E/2]);
Defined in: conic.js.
Extends JXG.Curve.

Class Detail
Conic(a,b,c,d,e, a_00,a_11,a_22,a_01,a_02,a_12)
- Parameters:
- {JXG.Point|Array_JXG.Point|Array_JXG.Point|Array_JXG.Point|Array_JXG.Point|Array} a,b,c,d,e
- Parent elements are five points.
- {Number_Number_Number_Number_Number_Number} a_00,a_11,a_22,a_01,a_02,a_12
- 6 numbers, i.e. A, C, F, B/2, D/2, E/2
- 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]);
// Parameters: A, C, F, B/2, D/2, E/2 var conic = board.create('conic', [1, 2, -4, 0, 0, 0]s);
