1.3 RELATION BETWEEN CARTESIAN AND CYLINDRICAL COORDINATE SYSTEM Spherical coordinates make it simple to describe a sphere, just as cylindrical coordinates make it easy to describe a cylinder. In this case, the triple describes one distance and two angles. In the spherical coordinate system, we again use an ordered triple to describe the location of a point in space.
In the Cartesian coordinate system, the location of a point in space is described using an ordered triple in which each coordinate represents a distance. The equations can often be expressed in more simple terms using cylindrical coordinates. These systems have complicated modeling equations in the Cartesian coordinate system, which make them difficult to describe and analyze. Physicists studying electrical charges and the capacitors used to store these charges have discovered that these systems sometimes have a cylindrical symmetry. The use of cylindrical coordinates is common in fields such as physics. In this case, the z -coordinates are the same in both rectangular and cylindrical coordinates. Use the second set of equations from Note to translate from rectangular to cylindrical coordinates. This is exactly the same process that we followed in Introduction to Parametric Equations and Polar Coordinates to convert from polar coordinates to two-dimensional rectangular coordinates. If this process seems familiar, it is with good reason.

Notice that these equations are derived from properties of right triangles. In this way, cylindrical coordinates provide a natural extension of polar coordinates to three dimensions. Starting with polar coordinates, we can follow this same process to create a new three-dimensional coordinate system, called the cylindrical coordinate system. When we expanded the traditional Cartesian coordinate system from two dimensions to three, we simply added a new axis to model the third dimension. Similarly, spherical coordinates are useful for dealing with problems involving spheres, such as finding the volume of domed structures.
As the name suggests, cylindrical coordinates are useful for dealing with problems involving cylinders, such as calculating the volume of a round water tank or the amount of oil flowing through a pipe. In this section, we look at two different ways of describing the location of points in space, both of them based on extensions of polar coordinates. This is a familiar problem recall that in two dimensions, polar coordinates often provide a useful alternative system for describing the location of a point in the plane, particularly in cases involving circles. Some surfaces, however, can be difficult to model with equations based on the Cartesian system.
