Equations: An equation is basically a math statement with an equal sign in the middle, for instance: In algebra, equations often include variables: We are often asked to simplify or solve them. They are similar but completely different things. [100%] 2024-01-19 [Algebra]
Equation (mathematics): Equation is kind of mathematical problem that is formulated in the following way: some equality is given, and at least one side of this equality is dependent on some variable (or variables); it is suggested to find values of variables ... (Physics) [87%] 2023-10-08
Equation: In mathematics, an equation is a mathematical formula that expresses the equality of two expressions, by connecting them with the equals sign =. The word equation and its cognates in other languages may have subtly different meanings; for example, in French ...

Equation (mathematics): In mathematics, an equation is a statement that two quantities are equal. It is usually regarded as a kind of mathematical problem in which you have to find a value which makes the equation true. (Mathematics) [87%] 2023-06-12
Equation: An analytical form of the problem of investigating which values of variables in functions give equal results. The arguments on which the functions depend are usually called the unknowns, and the values of the unknowns for which the values of ... (Mathematics) [87%] 2023-11-21
Equation: Equation, an expression or statement of the equality of two quantities. Mathematical equivalence is denoted by the sign =, a symbol invented by Robert Recorde (1510-1558), who considered that nothing could be more equal than two equal and parallel straight ... [87%] 2022-09-02

Equating: Test equating traditionally refers to the statistical process of determining comparable scores on different forms of an exam. It can be accomplished using either classical test theory or item response theory. (Social) [75%] 2023-09-02 [Psychometrics]
Kolmogorov equations (Markov jump process): In the context of a continuous-time Markov process, the Kolmogorov equations, including Kolmogorov forward equations and Kolmogorov backward equations, are a pair of systems of differential equations that describe the time-evolution of the probability \displaystyle{ P(x,s ...

Hamilton equations: Ordinary canonical first-order differential equations describing the motion of holonomic mechanical systems acted upon by external forces, as well as describing the extremals of problems of the classical calculus of variations. Hamilton's equations, established by W. (Mathematics) [70%] 2023-10-18
Kolmogorov equations: In probability theory, Kolmogorov equations, including Kolmogorov forward equations and Kolmogorov backward equations, characterize continuous-time Markov processes. In particular, they describe how the probability that a continuous-time Markov process is in a certain state changes over time. [70%] 2022-09-27 [Markov processes] [Stochastic models]...
Simultaneous equations: Simultaneous equations are finite sets of mathematical equations where the solution to the set of equations solves each individual equation. There are many different types of simultaneous equations, such as linear simultaneous equations and differential simultaneous equations. [70%] 2023-02-25 [Mathematics] [Algebra]...
Weingarten equations: The Weingarten equations give the expansion of the derivative of the unit normal vector to a surface in terms of the first derivatives of the position vector of a point on the surface. These formulas were established in 1861 by ... [70%] 2022-07-13 [Differential geometry of surfaces]
Laue equations: In crystallography and solid state physics, the Laue equations relate incoming waves to outgoing waves in the process of elastic scattering, where the photon energy or light temporal frequency does not change by scattering, by a crystal lattice. They are ... (Physics) [70%] 2023-03-31 [Crystallography]
Whitham equations: Perhaps the proper beginning of Whitham theory is Whitham's work , , which can be viewed as a crucible of various averaging ideas subsequently developed in e.g. , , , , , , , , , , , , to theories involving multi-phase averaging, Hamiltonian systems and weakly deformed soliton lattices. (Mathematics) [70%] 2023-11-14
Fresnel equations: The Fresnel equations (or Fresnel coefficients) describe the reflection and transmission of light (or electromagnetic radiation in general) when incident on an interface between different optical media. They were deduced by Augustin-Jean Fresnel (/freɪˈnɛl/) who was the first to ... (Equations of light transmission and reflection) [70%] 2022-09-27 [Light] [Geometrical optics]...
