1.
(a) (Math.) A term applied to some characteristic
magnitude whose value, invariable as long as one and
the same function, curve, surface, etc., is
considered, serves to distinguish that function,
curve, surface, etc., from others of the same kind or
family. --Brande & C.
(b) Specifically (Conic Sections), in the ellipse and

its conjugate, or in the parabola, to any abscissa and
the corresponding ordinate.
Note: The parameter of the principal axis of a conic section
is called the latus rectum.

which determines the position of any plane; also, the
