Attribution CC BY. 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 For example, Sullivan combines linear and quadratic functions into one short chapter while this text dedicates a long chapter solely to linear functions and uses that space to develop them more coherently. Sullivan pulls together some topics into an appendix as a review while this text does not.
Precalculus: An Investigation of Functions is a free, open textbook covering a two-quarter pre-calculus sequence including trigonometry. The first portion of the book is an investigation of functions, exploring the graphical behavior of, interpretation of, and solutions to problems involving linear, polynomial, rational, exponential, and logarithmic functions. An emphasis is placed on modeling and interpretation, as well as the important characteristics needed in calculus. The second portion of the book introduces trigonometry. Identities are introduced in the first chapter, and revisited throughout. Likewise, solving is introduced in the second chapter and revisted more extensively in the third chapter. As with the first part of the book, an emphasis is placed on motivating the concepts and on modeling and interpretation.
