2. Inverse Laplace transform - Wikipedia

   en.wikipedia.org/wiki/Inverse_Laplace_transform

   Post's inversion formula for Laplace transforms, named after Emil Post, [3] is a simple-looking but usually impractical formula for evaluating an inverse Laplace transform. The statement of the formula is as follows: Let f ( t ) {\displaystyle f(t)} be a continuous function on the interval [ 0 , ∞ ) {\displaystyle [0,\infty )} of exponential ...

3. Laplace transform - Wikipedia

   en.wikipedia.org/wiki/Laplace_transform

   In mathematics, the Laplace transform, named after Pierre-Simon Laplace (/ l ə ˈ p l ɑː s /), is an integral transform that converts a function of a real variable (usually , in the time domain) to a function of a complex variable (in the complex-valued frequency domain, also known as s-domain, or s-plane).

4. Symbolab - Wikipedia

   en.wikipedia.org/wiki/Symbolab

   Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011. In 2020, the company was acquired by American educational technology website Course Hero. [3] [4]

5. Mellin inversion theorem - Wikipedia

   en.wikipedia.org/wiki/Mellin_inversion_theorem

   In mathematics, the Mellin inversion formula (named after Hjalmar Mellin) tells us conditions under which the inverse Mellin transform, or equivalently the inverse two-sided Laplace transform, are defined and recover the transformed function.

6. List of Laplace transforms - Wikipedia

   en.wikipedia.org/wiki/List_of_Laplace_transforms

   The unilateral Laplace transform takes as input a function whose time domain is the non-negative reals, which is why all of the time domain functions in the table below are multiples of the Heaviside step function, u(t). The entries of the table that involve a time delay τ are required to be causal (meaning that τ > 0).

7. Jacobian matrix and determinant - Wikipedia

   en.wikipedia.org/wiki/Jacobian_matrix_and...

   This is the inverse function theorem. Furthermore, if the Jacobian determinant at p is positive , then f preserves orientation near p ; if it is negative , f reverses orientation. The absolute value of the Jacobian determinant at p gives us the factor by which the function f expands or shrinks volumes near p ; this is why it occurs in the ...

8. Laplace operator - Wikipedia

   en.wikipedia.org/wiki/Laplace_operator

   The Laplace–Beltrami operator, when applied to a function, is the trace (tr) of the function's Hessian: = ⁡ (()) where the trace is taken with respect to the inverse of the metric tensor. The Laplace–Beltrami operator also can be generalized to an operator (also called the Laplace–Beltrami operator) which operates on tensor fields, by a ...

9. Zero-order hold - Wikipedia

   en.wikipedia.org/wiki/Zero-order_hold

   The zero-order hold (ZOH) is a mathematical model of the practical signal reconstruction done by a conventional digital-to-analog converter (DAC). [1] That is, it describes the effect of converting a discrete-time signal to a continuous-time signal by holding each sample value for one sample interval.
