- Conic( <Point>, <Point>, <Point>, <Point>, <Point> )
- Returns a conic section through the five given points.
- Example:
Conic((0, -4), (2, 4), (3,1), (-2,3), (-3,-1))yields 151x² - 37x y + 72y² + 14x - 42y = 1320 .
- Note: If four of the points lie on one line, then the conic section is not defined.
- Conic( <Number a>, <Number b>, <Number c>, <Number d>, <Number e>, <Number f> )
- Returns a conic section a\cdot x^2+d\cdot xy+b\cdot y^2+e\cdot x+f\cdot y=-c.
- Example:
Conic(2, 3, -1, 4, 2, -3)yields 2x² + 4x y + 3y² + 2x - 3y = 1 .
- Conic( <List> )
- Returns a conic section a\cdot x^2+d\cdot xy+b\cdot y^2+e\cdot x+f\cdot y=-c.
- Example:
Conic({2, 3, -1, 4, 2, -3})yields 2x² + 4x y + 3y² + 2x - 3y = 1 .
