      1.2.2 Coordinate Systems

      Three coordinate systems are defined in this section: the rectangular or Cartesian coordinate system, the cylindrical coordinate system, and the spherical coordinate system.

      1.2.2.1 Cartesian Coordinate System

Unit vector representation for a Cartesian coordinate system is shown in Figure 1.3.

A vector representation in a Cartesian coordinate system is given by (1.17).

(1.17)

      The magnitude of vector is found from

      (1.18)

The vector can be illustrated in the coordinate system, as shown in Figure 1.4. The base vector properties can be given by
