Math-Complex: correct typos in documentation

- Correct typo where "pi" should be "phi".

- Spherical coordinates should use the same order of the coordinates
  everywhere, i.e., rho, theta, phi.

+Spherical coordinates, I<(rho, theta, phi)>, are three-dimensional
 coordinates which define a point in three-dimensional space.  They are
 based on a sphere surface.  The radius of the sphere is B<rho>, also
 known as the I<radial> coordinate.  The angle in the I<xy>-plane
 (around the I<z>-axis) is B<theta>, also known as the I<azimuthal>
 coordinate.  The angle from the I<z>-axis is B<phi>, also known as the
-I<polar> coordinate.  The North Pole is therefore I<0, 0, rho>, and
