LinearEccentricity Command
From GeoGebra Manual
- LinearEccentricity[ <Conic> ]
- Calculates the linear eccentricity of the conic section.
For ellipses or hyperbolas: gives the distance between the conic's center and one of its foci.
- Example:
LinearEccentricity[4x^2 - y^2 + 16x + 20 = 0]returns 2.24
For circles: gives 0
For parabolas: gives the distance between the focus and the vertex
