Abstract

Most people are familiar with the idea of plotting a graph. This is one example of a coordinate system, the x and y coordinates (abscissa and ordinate) providing a means of specifying the position of a point within the two-dimensional surface occupied by the graph. It is a simple extension of the idea to give completely the position of an object in space using three coordinates, x, y and z (Figure 4.1).
