Class Detail
Conic(point,point,point,point,point, 6)
// 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:
- {JXG.Point|array_JXG.Point|array_JXG.Point|array_JXG.Point|array_JXG.Point|array_} point,point,point,point,point
- Parent elements are five points.
- {number_number_number_number_number_number} 6
- 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.
