This text contains most of the familiar methods of approximate inversion of the Laplace transformation and calculation of Fourier integrals. This book is designed for scientists and engineers that have to deal with the theory and applications of the Laplace transform and Fourier integrals. It will be a useful handbook in every computer centre and designing bureau. -- Contents: List of Symbols; Preface; Part 1: Inversion of the Laplace Transformation 1.
