dimensional, usually in reference to some structure. Examples
include: 1) a signal that is a function of time , 2) the
dimensionality of a single property value or 3) one degree of
freedom in shape variation or motion. 2D: Two dimensional. A
space describable using any pair of orthogonal basis vectors
consisting of two elements. 2D coordinate system: A system
associating uniquely 2 real numbers to any point of a plane.
First, two intersecting lines (axes) are chosen on the plane,
usually perpendicular to each other. The point of intersection
is the origin of the system. Second, metric units are
established on each axis (often the same for both axes) to
associate numbers to points. The coordinates and of a point, P,
are obtained by projecting P onto each axis in a di
