Thomas's Calculus is one of the most internationally recognized textbooks at the undergraduate level. In this fully revised edition, the authors present a modern introduction to calculus, while remaining true to the traditional "formula" of the book's international success: mathematically accurate, carefully balanced between rigor and qualitative understanding of concepts, presented in a way that supports the development of mathematical maturity, without the need for memorizing formulas and repetitive processes.

The material is presented through targeted examples with detailed explanations accompanied by numerous exercises of varying difficulty. Many of the exercises and problems require the use of a computer for exploration and solution.

A key feature of the book is the applied problems, which are continuously updated and enriched in the latest editions, drawing topics from physics and engineering sciences, chemistry and biology, as well as from economics and social sciences.

This new edition includes a separate chapter on second-order differential equations, which is available only online from this website. With the richness of its content and the flexibility provided by its structure, Calculus can be used in a wide range of different university courses, from the most theoretical to the most applied.

The instructor can choose to what extent to incorporate the optional—but essential—computational applications into the course. In any case, the reader cannot help but appreciate Calculus as a remarkable intellectual tool for interpreting, understanding, and managing the world around us.
