Usage (signatures)

board.create('conic', [A, B, C, D, E]);

Parent elements are five points.

Parameters

Name	Type	Description
`A`	PointLike
`B`	PointLike
`C`	PointLike
`D`	PointLike
`E`	PointLike

Example

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]);

board.create('conic', [a_00, a_11, a_22, a_01, a_02, a_12]);

Parent elements are 6 numbers, i.e. A, C, F, B/2, D/2, E/2
