Textbook in PDF format
Precalculus 2e provides a comprehensive exploration of mathematical principles and meets scope and sequence requirements for a typical precalculus course. The text proceeds from functions through trigonometry and ends with an introduction to calculus. The modular approach and the richness of content ensure that the book addresses the needs of a variety of courses. Precalculus 2e offers a wealth of examples with detailed, conceptual explanations, building a strong foundation in the material before asking students to apply what they’ve learned.
The Precalculus 2e revision focused on improving relevance and representation as well as mathematical clarity and accuracy. Introductory narratives, examples, and problems were reviewed and revised using a diversity, equity, and inclusion framework. Many contexts, scenarios, and images have been changed to become even more relevant to students’ lives and interests. To maintain our commitment to accuracy and precision, examples, exercises, and solutions were reviewed by multiple faculty experts. All improvement suggestions and errata updates from the first edition were considered and unified across the different formats of the text. The first edition of Precalculus by OpenStax is also available.
This is the official print version of this OpenStax textbook. OpenStax makes full-color hardcover and B&W paperback print copies available for students who prefer a hardcopy textbook to go with the free digital version of this OpenStax title. The textbook content is exactly the same as the OpenStax digital book. This textbook is available for free download at the OpenStax dot org website, but as many students prefer to study with hardcopy books, we offer affordable OpenStax textbooks for sale through Amazon as well as most campus bookstores.
