conic
adj 1: relating to or resembling a cone; "conical mountains";
"conelike fruit" [synonym: {conic}, {conical}, {conelike},
{cone-shaped}]
n 1: (geometry) a curve generated by the intersection of a plane
and a circular cone [synonym: {conic section}, {conic}]

Conic \Con"ic\, n. (Math.)
A conic section.
[1913 Webster]


Conic \Con"ic\, Conical \Con"ic*al\, a. [Gr. ?: cf. F. conique.
See {Cone}.]
1. Having the form of, or resembling, a geometrical cone;
round and tapering to a point, or gradually lessening in
circumference; as, a conic or conical figure; a conical
vessel.
[1913 Webster]

2. Of or pertaining to a cone; as, conic sections.
[1913 Webster]

{Conic section} (Geom.), a curved line formed by the
intersection of the surface of a right cone and a plane.
The conic sections are the parabola, ellipse, and
hyperbola. The right lines and the circle which result
from certain positions of the plane are sometimes, though
not generally included.

{Conic sections}, that branch of geometry which treats of the
parabola, ellipse, and hyperbola.

{Conical pendulum}. See {Pendulum}.

{Conical projection}, a method of delineating the surface of
a sphere upon a plane surface as if projected upon the
surface of a cone; -- much used by makers of maps in
Europe.

{Conical surface} (Geom.), a surface described by a right
line moving along any curve and always passing through a
fixed point that is not in the plane of that curve.
[1913 Webster]
