The fundamental plane in a spherical coordinate system is a plane of reference that divides the sphere into two hemispheres. The geocentric latitude of...

The fundamental plane may refer to: Fundamental plane (spherical coordinates), which divides a spherical coordinate system Fundamental plane (elliptical...

coordinate systems based on different fundamental planes and with different terms for the various coordinates. The spherical coordinate systems used in mathematics...

may be implemented in spherical or rectangular coordinates, both defined by an origin at the centre of Earth, a fundamental plane consisting of the projection...

galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with...

plane. In mathematics, analytic geometry (also called Cartesian geometry) describes every point in two-dimensional space by means of two coordinates....

are called harmonics. Despite their name, spherical harmonics take their simplest form in Cartesian coordinates, where they can be defined as homogeneous...

analogous to the spherical coordinate system defined for ⁠ 3 {\displaystyle 3} ⁠-dimensional Euclidean space, in which the coordinates consist of a radial...

the angle θ its projection on the xy-plane makes with respect to the horizontal axis. In spherical coordinates, every point in space is represented by...

Greek mathematicians. The sphere is a fundamental object in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry...

astrometry. The primary elements of spherical astronomy are celestial coordinate systems and time. The coordinates of objects on the sky are listed using...

A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude...

system that uses the observer's local horizon as the fundamental plane to define two angles of a spherical coordinate system: altitude and azimuth. Therefore...

geometry, a conic may be defined as a plane algebraic curve of degree 2; that is, as the set of points whose coordinates satisfy a quadratic equation in two...
