The mean radius of the Earth, in the sense of the radius of a sphere having the same volume as the actual geoid, is a \(\sqrt[3]{a^2 c} = 6371.00 \text{ km}\).

In lieu of x and y , the cylindrical system uses ρ , the distance measured from the closest point on the z axis,1 and ϕ , the angle measured in a plane of constant z , beginning at the +x axis ( ϕ=0 ) with ϕ increasing toward the +y direction.

In order to connect the phenomena to mathematics we begin by introducing the concept of a coordinate system. A coordinate system consists of four basic elements: (1) Choice of origin, (2) Choice of axes, (3) Choice of positive direction for each axis and (4) Choice of unit vectors at every point in space. There are three commonly used coordinate systems: Cartesian, cylindrical and spherical. In this chapter, we will describe a
