- Axes( <Conic> )
- Returns the equations of the major and minor axes of a conic section.
- Axes( <Quadric> )
- Creates the 3 axes of the given quadric.
- Example:a: X = (0, 0, 0) + λ (1, 0, 0), b: X = (0, 0, 0) + λ (0, 1, 0) and c: X = (0, 0, 0) + λ (0, 0, 1)
Axes(x^2 + y^2 + z^2= 3)
returns the three lines
- Notes: Specifically:
- if the given quadric is a cylinder, the command yields the two axes of the bottom circle and the rotation axis.
- if the given quadric is a sphere, the command yields the three axes parallel to the coordinate system axes.
