- LinearEccentricity[ <Conic> ]
- Calculates the linear eccentricity of the conic section,
For ellipse or hyperbola the distance between the conic center and one of its foci.
- Example:
LinearEccentricity[4x^2 - y^2 + 16x + 20 = 0]
returns 2.24
For circle, return 0
For parabola, the distance between the focus and the vertex
