The Laplace transform is an integral transform perhaps second only to the Fourier transform in its utility in solving physical problems. The Laplace transform is particularly useful in solving linear ordinary differential equations such as those arising in the analysis of electronic circuits. The unilateral Laplace transform not to be confused with the Lie derivative , also commonly denoted is defined by. The unilateral Laplace transform is almost always what is meant by "the" Laplace transform, although a bilateral Laplace transform is sometimes also defined as. Oppenheim et al. The unilateral Laplace transform is implemented in the Wolfram Language as LaplaceTransform [ f[t] , t , s ] and the inverse Laplace transform as InverseRadonTransform.

Integral transforms are linear mathematical operators that act on functions to alter the domain. Transforms are used to make certain integrals and differential equations easier to solve algebraically. There are many types of integral transforms with a wide variety of uses, including image and signal processing, physics, engineering, statistics and mathematical analysis. Decompose a function using the Fourier transform. Find the Mellin transform of a math function. Use a Laplace transform to take a function of a real variable to a function of a complex variable. Compute the discrete Z-transform of a mathematical expression. Uh oh! Wolfram Alpha doesn't run without JavaScript. Please enable JavaScript. If you don't know how, you can find instructions here.
