This command differs among variants of English:
|
- Center( <Conic> )
- Returns the center of a circle, ellipse, or hyperbola.
- Example:
Center(x^2 + 4 y^2 + 2x - 8y + 1 = 0)
(, :Centre(x^2 + 4 y^2 + 2x - 8y + 1 = 0)
)
returns point A = (-1, 1)
Note: See also Midpoint or Center (, : Midpoint or Centre) tool .
- Center( <Quadric> )
- Creates the center of a quadric (e.g. sphere, cone, etc.).
- Example:
Center(x^2 + (y-1)^2 + (z-2)^2 = 1)
yields (0, 1, 2)
