Information about the series: The modular structure of the books allows for individual focus areas; students can easily navigate through the material. The content is clearly presented on mostly two-column pages: teaching texts and solution structures are on the left, while proof details, calculations, and sketches are placed on the right. All important methods, terms, and procedures are introduced and explained through instructive, fully worked-out examples. These examples support the teaching text, clarifying definitions, theorems, and procedures. There are no lengthy theoretical discussions without practical application. The exercises that follow are precisely aligned with the examples, definitions, and procedures. Each section concludes with an additional collection of tasks, including composite problems. Applications and modeling are also taken into account.
