               2.6    POSITION VECTORS AND x, y, z COORDINATES


               Throughout this module, the right-handed coordinate system will be use to refer the location of a

               point in space. The right-handed coordinate system is a universal system and is used in many
               technical areas. The positive z axis is directed upward so that is shows the altitude of the object or

               in another word it is measures the height of an object. The x, y axes then lie in the horizontal plane
