  2. WolframAlpha - Wikipedia

    en.wikipedia.org/wiki/WolframAlpha

    It is offered as an online service that answers factual queries by computing answers from externally sourced data. [4] [5] WolframAlpha was released on May 18, 2009, and is based on Wolfram's earlier product Wolfram Mathematica, a technical computing platform. [1] WolframAlpha gathers data from academic and commercial websites such as the CIA ...

  3. Lambert W function - Wikipedia

    en.wikipedia.org/wiki/Lambert_W_function

    The Lambert W function is used to solve equations in which the unknown quantity occurs both in the base and in the exponent, or both inside and outside of a logarithm. The strategy is to convert such an equation into one of the form zez = w and then to solve for z using the W function. For example, the equation.

  4. Wolfram Mathematica - Wikipedia

    en.wikipedia.org/wiki/Wolfram_Mathematica

    Wolfram Mathematica is a software system with built-in libraries for several areas of technical computing that allow machine learning, statistics, symbolic computation, data manipulation, network analysis, time series analysis, NLP, optimization, plotting functions and various types of data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in ...

  5. Cauchy–Euler equation - Wikipedia

    en.wikipedia.org/wiki/Cauchy–Euler_equation

    Cauchy–Euler equation. In mathematics, an Euler–Cauchy equation, or Cauchy–Euler equation, or simply Euler's equation is a linear homogeneous ordinary differential equation with variable coefficients. It is sometimes referred to as an equidimensional equation. Because of its particularly simple equidimensional structure, the differential ...

  6. Method of characteristics - Wikipedia

    en.wikipedia.org/wiki/Method_of_characteristics

    t. e. In mathematics, the method of characteristics is a technique for solving partial differential equations. Typically, it applies to first-order equations, although more generally the method of characteristics is valid for any hyperbolic partial differential equation.

  7. Formula editor - Wikipedia

    en.wikipedia.org/wiki/Formula_editor

    Formula editor. A formula editor is a computer program that is used to typeset mathematical formulas and mathematical expressions . Formula editors typically serve two purposes: They allow word processing and publication of technical content either for print publication, or to generate raster images for web pages or screen presentations.

  8. Wolfram Language - Wikipedia

    en.wikipedia.org/wiki/Wolfram_Language

    The Wolfram Language ( / ˈwʊlfrəm / WUUL-frəm) is a proprietary, [7] general very high-level multi-paradigm programming language [8] developed by Wolfram Research. It emphasizes symbolic computation, functional programming, and rule-based programming [9] and can employ arbitrary structures and data. [9] It is the programming language of the ...

  9. Partial differential equation - Wikipedia

    en.wikipedia.org/wiki/Partial_differential_equation

    e. In mathematics, a partial differential equation ( PDE) is an equation which computes a function between various partial derivatives of a multivariable function . The function is often thought of as an "unknown" to be solved for, similar to how x is thought of as an unknown number to be solved for in an algebraic equation like x2 − 3x + 2 = 0.
