## Description

This textbook offers an accessible and highly approved approach that is characterized by combining the textbook with a study guide available online in our extras.springer.com repository. This study guide divides the entire learning task into small units that the student is most likely to master successfully. Therefore, read what you study and study limited textbook information and return to the study guide later.

Working with the study guide, the learning outcomes are controlled, monitored and deepened by qualified questions, exercises, repetitions and finally problems and applications of the content studied. As the degree of difficulty is slowly increasing, students gain confidence and experience their own progress in mathematical competence, thus encouraging motivation. In addition, in the case of learning difficulties, additional explanations are given and in the case of individual needs, complementary exercises and applications. So the sequence of studies is individualized according to individual performance and needs and can be considered as complete tutorial course.

The study guide satisfies the objectives simultaneously: first, it allows students to make effective use of the textbook and, secondly, offers advice on improving study skills. Empirical studies have shown that the student’s competence to use information has been improved by using this study guide.

The new edition includes a new chapter on Fourier integrals and Fourier transform, sections have been updated, 30 new problems have been added with solutions. The interactive study guide has seen a substantial update.
