  2. Laplace transform applied to differential equations - Wikipedia

    en.wikipedia.org/wiki/Laplace_transform_applied...

    In mathematics, the Laplace transform is a powerful integral transform used to switch a function from the time domain to the s-domain. The Laplace transform can be used in some cases to solve linear differential equations with given initial conditions. First consider the following property of the Laplace transform: One can prove by induction that.

  3. Laplace transform - Wikipedia

    en.wikipedia.org/wiki/Laplace_transform

    The Laplace transform can also be used to solve differential equations and is used extensively in mechanical engineering and electrical engineering. The Laplace transform reduces a linear differential equation to an algebraic equation, which can then be solved by the formal rules of algebra.

  4. Spectral method - Wikipedia

    en.wikipedia.org/wiki/Spectral_method

    Spectral methods are a class of techniques used in applied mathematics and scientific computing to numerically solve certain differential equations. The idea is to write the solution of the differential equation as a sum of certain "basis functions" (for example, as a Fourier series which is a sum of sinusoids) and then to choose the ...

  5. Adomian decomposition method - Wikipedia

    en.wikipedia.org/wiki/Adomian_decomposition_method

    The Adomian decomposition method (ADM) is a semi-analytical method for solving ordinary and partial nonlinear differential equations. The method was developed from the 1970s to the 1990s by George Adomian, chair of the Center for Applied Mathematics at the University of Georgia. [1] It is further extensible to stochastic systems by using the ...

  6. Classical control theory - Wikipedia

    en.wikipedia.org/wiki/Classical_control_theory

    Classical control theory. Classical control theory is a branch of control theory that deals with the behavior of dynamical systems with inputs, and how their behavior is modified by feedback, using the Laplace transform as a basic tool to model such systems. The usual objective of control theory is to control a system, often called the plant ...

  7. Separation of variables - Wikipedia

    en.wikipedia.org/wiki/Separation_of_variables

    t. e. In mathematics, separation of variables (also known as the Fourier method) is any of several methods for solving ordinary and partial differential equations, in which algebra allows one to rewrite an equation so that each of two variables occurs on a different side of the equation.

  8. Low-pass filter - Wikipedia

    en.wikipedia.org/wiki/Low-pass_filter

    A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design. The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications.

  9. Wiener–Hopf method - Wikipedia

    en.wikipedia.org/wiki/Wiener–Hopf_method

    The Wiener–Hopf method is a mathematical technique widely used in applied mathematics.It was initially developed by Norbert Wiener and Eberhard Hopf as a method to solve systems of integral equations, but has found wider use in solving two-dimensional partial differential equations with mixed boundary conditions on the same boundary.
