Details and Options
The input
expr can be an equation or an
Association of ellipse properties. In this case,
ResourceFunction["EllipseProperties"] will calculate and return the full set of properties.
Ellipse properties include "Equation", "Foci", "Vertices", "Covertices", "Eccentricity", "Center", "SemimajorAxisLength", "SemiminorAxisLength", "AreaEnclosed", "SemiLatusRectum", "Directrices", "AxesOfSymmetry", "Circumference", "RotationAngle" and "BaseConic".
The
"BaseConic" property is an
Association of the properties
"Equation",
"RotationAngle" and
"DisplacementFromOrigin", where
"Equation" represents an isomorphic conic section based at the origin and aligned with the
x-axis.
If the given
expr describes a conic section other than a ellipse,
ResourceFunction["EllipseProperties"] will issue a message and return an
Association of properties pertaining to the correct conic section.
