### Goals

Presentation of basic mathematical concepts required for computing and using Fourier Transform and Laplace Transform. The first section is devoted to the presentation of the analytic functions of a complex variable and to the integration of a complex-valued function along a curve in the complex plan. The second section presents the expansion of a periodic function in Fourier Series and the Fourier Transform of absolutely summable functions. In the third section the Laplace Transform is explained. The usability of these Transforms in solving differential equations is also presented.
