A curve joining all points (loci) around two
fixed points (foci) such that the sum of the
distances from those points is always
constant. The diameter passing through the
foci is the major axis, and the diameter
bisecting this at right angles is the minor
axis. An ellipse is one of a series of curves
known as conic sections. A slice across a
cone that is not made parallel to, or does
not pass through, the base will produce an
ellipse.
