In **cartesian coordinates** (or **rectangular coordinates**), a
point *P* is referred to by three real numbers, indicating the
positions of the perpendicular projections from the point to three
fixed, perpendicular, graduated lines, called the **axes**. If the
coordinates are denoted *x*, *y*, *z*, in that order, the axes are called
the ** x-axis**, etc., and we write

**Figure 1:** In cartesian coordinates, *P*=(4.2,3.4,2.2).
