When one wants to calculate an improper Riemann integral one is facing various pitfalls. This is why an enormous amount of examples, exercises, and problems is la raison d'etre of this book, which is devoted to the calculation of improper Riemann integrals. Moreover, the author does his best to make the book as accessible as possible. ... I can recommend this book, which shows to students, among other things, the power of 'elementary techniques.' -Mathematical Reviews, January 2015 By collecting a lot of important improper integrals and sums used in various domains, and presenting their calculation in an accessible but rigorous way, the book will be of great use to students in mathematics and related areas and for applied scientists (statisticians, engineers, physicists) as well. -Studia Universitatis Babes-Bolyai Mathematica, 59, 2014
