This book of problems, designed as a practical tool for engineering students, is based on the author's experience of about 40 years teaching Mathematical Analysis at the University of Porto, Faculty of Engineering. It includes three chapters focused on differential equations, which have wide applications in the field of engineering, as well as a chapter introducing Laplace transforms and its application to ordinary differential equations. The final three chapters cover problems of line and surface integrals, as well as Fourier series.
