Variable (mathematics) — In mathematics, a variable is a value that may change within the scope of a given problem or set of operations. In contrast, a constant is a value that remains unchanged, though often unknown or undetermined.[1] The concepts of constants and… … Wikipedia
Variable range hopping — IntroductionVariable range hopping or Mott variable range hopping, is a model describing low temperature conduction in strongly disordered systems with localized states. [Mott, N.F., Phil. Mag. ,19,835,1969] It has a characteristic temperature… … Wikipedia
Cartesian coordinate system — Illustration of a Cartesian coordinate plane. Four points are marked and labeled with their coordinates: (2, 3) in green, (−3, 1) in red, (−1.5, −2.5) in blue, and the origin (0, 0) in purple. A Cartesian coordinate system specifies each point… … Wikipedia
Polar coordinate system — Points in the polar coordinate system with pole O and polar axis L. In green, the point with radial coordinate 3 and angular coordinate 60 … Wikipedia
Green's function for the three-variable Laplace equation — The free space Green s function for the three variable Laplace equation is given in terms of the reciprocal distance between two points. That is to say the solution of the equation : abla^2 G(mathbf{x},mathbf{x }) = delta(mathbf{x} mathbf{x }) is … Wikipedia
Homogeneous coordinate system — A homogeneous coordinate system is a coordinate system in which there is an extra dimension, used most commonly in computer science to specify whether the given coordinates represent a vector (if the last coordinate is zero) or a point (if the… … Wikipedia
Horizontal coordinate system — The horizontal coordinate system is a celestial coordinate system that uses the observer s local horizon as the fundamental plane. This conveniently divides the sky into the upper hemisphere that you can see, and the lower hemisphere that you… … Wikipedia
Geocentric Coordinate Time — (TCG) is a coordinate time standard intended to be used as the independent variable of time for all calculations pertaining to precession, nutation, the Moon, and artificial satellites of the Earth. It is equivalent to the proper time experienced … Wikipedia
Barycentric Coordinate Time — (TCB) is a coordinate time standard intended to be used as the independent variable of time for all calculations pertaining to orbits of planets, asteroids, comets, and interplanetary spacecraft in the Solar system. It is equivalent to the proper … Wikipedia
List of common coordinate transformations — This is a list of some of the most commonly used coordinate transformations. Contents 1 2 Dimensional 1.1 To Cartesian coordinates from polar coordinates 1.2 To polar coordinates from Cartesian coordinates … Wikipedia
complex variable — Math. a variable to which complex numbers may be assigned as value. [1875 80] * * * In mathematics, a variable that can take on the value of a complex number. In basic algebra, the variables x and y generally stand for values of real numbers. The … Universalium
