The "'fundamental plane "'in a spherical coordinate system is a point is then the angle between the fundamental plane and the line joining the point to the centre of the sphere.

To define a spherical coordinate system, one must choose two orthogonal directions, the " zenith " and the " azimuth reference ", and an " origin " point in space.

The closest example I can think of would be the placing of the prime meridian in Greenwich, London, although that is a Spherical coordinate system . talk ) 05 : 11, 30 November 2008 ( UTC)

I think some people have already said it, about the definition of down being towards the centre of the earth, I thought perhapes links to Spherical coordinate system and comparing it to Cartesian coordinate system might be interesting.

By direct substitution, the solution to this equation can be readily shown to be the scalar Green's function, which in the spherical coordinate system ( and using the physics time convention e ^ {-i \ omega t } ) is:

This is an approximate equation that is derived from the incompressible Navier Stokes equations ( written in spherical coordinate system ) and describes the motion of the radius of the bubble " R " as a function of time " t ".

In mathematics, a "'spherical coordinate system "'is a coordinate system for azimuth angle "'of its orthogonal projection on a reference plane that passes through the origin and is orthogonal to the zenith, measured from a fixed reference direction on that plane.
