Axes[ <Conic> ]: Returns the equations of the major and minor axes of a conic section.; Example: Axes[x^2 + 4 y^2 + 2x - 8y + 1 = 0] returns line a: y = 1 and line b: x = -1

Following text is about a feature that is supported only in GeoGebra 5.0.

Axes [ <Quadric> ]: Create the 3 axes of a 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)

Note: See also MajorAxis and MinorAxis commands.
