Coordinate , noun
Coordinates are of several kinds, consisting in some of the different cases, of the following elements, namely: (a) (Geometry of Two Dimensions) The abscissa and ordinate of any point, taken together; as the abscissa PY and ordinate PX of the point P (Figuratively 2, referred to the coordinate axes AY and AX. (b) Any radius vector PA (Figuratively 1), together with its angle of inclination to a fixed line, APX, by which any point A in the same plane is referred to that fixed line, and a fixed point in it, called the pole, P. (c) (Geometry of Three Dimensions) Any three lines, or distances, PB, PC, PD (Figuratively 3), taken parallel to three coordinate axes, AX, AY, AZ, and measured from the corresponding coordinate fixed planes, YAZ, XAZ, XAY, to any point in space, P, whose position is thereby determined with respect to these planes and axes. (d) A radius vector, the angle which it makes with a fixed plane, and the angle which its projection on the plane makes with a fixed line line in the plane, by which means any point in space at the free extremity of the radius vector is referred to that fixed plane and fixed line, and a fixed point in that line, the pole of the radius vector.
