- In mathematics,
a quadric or
quadric surface (
quadric hypersurface in
higher dimensions), is
a generalization of conic sections (ellipses, parabolas, and...

ellipsoid is
a quadric surface; that is,
a surface that may be
defined as the zero set
of a polynomial of degree two in
three variables.
Among quadric surfaces...

Quadric geometric algebra (QGA) is

extension of the
concept of confocal conics to

Cauchy saw how
their work
could be used to
classify the
quadric surfaces, and
generalized it to
arbitrary dimensions.
Cauchy also coined...
