Axes[ <Conic> ]: Returns the equations of the major and minor axes of a conic section.

Note: See also MajorAxis and MinorAxis commands.

This page is about a feature that is supported only in GeoGebra 5.0.

Axes[ <Quadric> ]: Creates the 3 axes of the given quadric.; Example:
Axes[x^2 + y^2 = 3] returns the three lines
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)

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 ones of the coordinate system.
