spherical coordinates
11Fundamental plane (spherical coordinates) — The fundamental plane in a spherical coordinate system is a plane which divides the sphere into two hemispheres. The latitude of a point is then the angle between the fundamental plane and the line joining the point to the centre of the… …
12Spherical coordinate system — In mathematics, the spherical coordinate system is a coordinate system for representing geometric figures in three dimensions using three coordinates: the radial distance of a point from a fixed origin, the zenith angle from the positive z axis… …
13Spherical harmonics — In mathematics, the spherical harmonics are the angular portion of an orthogonal set of solutions to Laplace s equation represented in a system of spherical coordinates. Spherical harmonics are important in many theoretical and practical… …
14Spherical pendulum — A spherical pendulum is a generalization of the pendulum.It consists of a mass moving without friction on a sphere. The only forces acting on the mass are the reaction from the sphere and gravity.It is convenient to use spherical coordinates and… …
15coordinates — Linear or angular quantities which designate the position that a point occupies in a given reference frame or system. Also used as a general term to designate the particular kind of reference frame or system such as plane rectangular coordinates… …
16spherical coordinate system — In geometry, a coordinate system in which any point in three dimensional space is specified by its angle with respect to a polar axis and angle of rotation with respect to a prime meridian on a sphere of a given radius. In spherical coordinates a …
17spherical harmonics — noun The solutions to Laplaces equation using spherical coordinates …
18Spherical astronomy — or positional astronomy is the branch of astronomy that is used to determine the location of objects on the celestial sphere, as seen at a particular date, time, and location on the Earth. This is one of the oldest branches of astronomy. It… …
