## Laplace transform

Introduction to Applied Mathematics pp Cite as. We pause in our discussion of partial differential equations to develop two techniques for treating problems in the infinite domain. One of these, the Laplace transform, is the continuous analog of the Z -transform, which we recall was developed for treating difference equations. The other technique, the infinite Fourier transform, is the extension to the infinite domain of Fourier series. The last we recall was itself the continuous version of the discrete Fourier transform. Since the Z- and the discrete Fourier transforms are themselves related, all these methods are connected to one another.

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.

## Laplace and Fourier Transforms

Make a short draft of properties of Laplace transform from memory. Then compare your notes with the text and write a report of pages on these operations and their significance in applications. Periodic function, Fourier series, Fourier series expansion of an arbitrary period, Half range expansions.

The transform has many applications in science and engineering because it is a tool for solving differential equations. In particular, it transforms differential equations into algebraic equations and convolution into multiplication. The Laplace transform is named after mathematician and astronomer Pierre-Simon Laplace , who used a similar transform in his work on probability theory. Laplace's use of generating functions was similar to what is now known as the z-transform , and he gave little attention to the continuous variable case which was discussed by Niels Henrik Abel.

In this note we propose a generalization of the Laplace and Fourier transforms which we call symmetric Laplace transform. It combines both the advantages of the Fourier and Laplace transforms.
