The book covers all of the necessary topics, but is a little light on the proofs/justifications of some of the facts. read more

The topics covered are standard in state articulation guides, for example, the 2019 Illinois Mathematics & Computer Science Articulation Guide. See the topics covered under "Elementary Functions (Precalculus)" which refers back to the tables... read more

I used Sullivan's Calculus (9e) as a standard for comparisons. The book is very similar in scope and sequencing to Sullivan, but does group some topics differently. For example, Sullivan combines linear and quadratic functions into one short... read more

The textbook covers all standard area and ideas for a Precalculus course. It also provides some advanced contents that are linked to Calculus. A review of basic algebra contents at the beginning of the text could have added good flavor to the... read more

Reviewed by Jaewoo Jeong, Associate Professor, Miami University on 2/1/18

It seems to cover all topics of Precalculus and also covers some preview of Calculus. However, the text does not cover review of Algebra. If it also covers a little bit of reviews such as basic factoring and other topics from Algebra, then it... read more

  • About the Book

    Precalculus is intended for college-level precalculus students. Since precalculus courses vary from one institution to the next, we have attempted to meet the needs of as broad an audience as possible, including all of the content that might be covered in any particular course. The result is a comprehensive book that covers more ground than an instructor could likely cover in a typical one- or two-semester course; but instructors should find, almost without fail, that the topics they wish to include in their syllabus are covered in the text. Many chapters of Openstax College Precalculus are suitable for other freshman and sophomore math courses such as College Algebra and Trigonometry; however, instructors of those courses might need to supplement or adjust the material. Openstax will also be releasing College Algebra and Algebra and Trigonometry titles tailored to the particular scope, sequence, and pedagogy of those courses.

    OpenStax College has compiled many resources for faculty and students, from faculty-only content to interactive homework and study guides.
