Conic section

Branches
one of the two symmetrical parts of the hyperbola.
Transverse Axis
the axis of symmetry of a hyperbola that contains the vertices and
foci.
Vertices of a hyperbola
the endpoints of the transverse axis of the hyperbola
Conjugate Axis
the axis of symmetry of a hyperbola that seperates the two
branches of the hyperbola.
Co-vertices of a hyperbola
the endpoints of the conjugate axis.
Focus (of a parabola)
a fixed point F used with a directrix to define a parabola.
Directrix
the fixed line used to define a parabola. every point on the parabola
is equidistant from the directrix and a fixed point called the focus.
Nonlinear system of equations
a system in which at least one of the equations is not linear.
Foci of an Ellipsis
one of two fixed points F and G that are used to define a ellipse. for
every point P on the ellipse. PF + PG is constant.
Vertex of a parabola
the highest or lowest point on the parabola.
