Position vector in cylindrical coordinates.
These axes allow us to name any location within the plane. In three dimensions, we define coordinate planes by the coordinate axes, just as in two dimensions. There are three axes now, so there are three intersecting pairs of axes. Each pair of axes forms a coordinate plane: the xy-plane, the xz-plane, and the yz-plane (Figure 2.26).
The spherical coordinate system is defined with respect to the Cartesian system in Figure 4.4.1. The spherical system uses r, the distance measured from the origin; θ, the angle measured from the + z axis toward the z = 0 plane; and ϕ, the angle measured in a plane of constant z, identical to ϕ in the cylindrical system. The third equation is just an acknowledgement that the z z -coordinate of a point in Cartesian and polar coordinates is the same. Likewise, if we have a point in Cartesian coordinates the cylindrical coordinates can be found by using the following conversions. r =√x2 +y2 OR r2 = x2+y2 θ =tan−1( y x) z =z r = x 2 + y 2 OR r 2 = x 2 + y …Similarly a vector in cylindrical polar coordinates is described in terms of the parameters r, θ and z since a vector r can be written as r = rr + zk.

Note: This page uses common physics notation for spherical coordinates, in which is the angle between the z axis and the radius vector connecting the origin to the point in question, while is the angle between the projection of the radius vector onto the x-y plane and the x axis. Several other definitions are in use, and so care must be taken in comparing different sources. Since we do not know the coordinates of QM or the values of n and m, we cannot simplify the equation.
