Precalculus / College Algebra, 3rd Edition

Carl Stitz, Jeff Zeager
The first half of a precalculus series, covering college algebra. This text takes a "functions first" approach, introducing the idea of a function early. Then as each class of functions is introduced, equations, inequalities, and applications involving functions in that class are discussed. The material is presented at a level to prepare the student for calculus an well as give them relevant mathematics which can be used in other classes as well. Graphing utilities are used sparingly to enhance the mathematics. The exercise sets were intentionally kept smaller to cover all the necessary skills and get the students thinking more deeply about the mathematics involved.

Openness Comments: Besides the non-commercial restriction, the use of MetaPost with TeX makes compiling the text after changes a non-trivial task. The authors have tried to help with this by posting how-to videos.

  • MyOpenMath / Lumen OHM online homework. MyOpenMath is a free online homework system, built on the open source IMathAS assessment platform. It provides randomized, algorithmically generated homework with automated grading of numerical and algebraic answers, similar to WebAssign and MyMathLab. It also provides a course management system with gradebook, file posting, discussion forums, etc. Assessment sets have been created for this textbook, which may be available for self-study by students, or can copied as a starter course shell by faculty.

    MyOpenMath use is free with community support through forums. For Washington State faculty, the site also mirrors this content.

    Lumen OHM is a commercial alternative to MyOpenMath that provides support for faculty and large scale adoption and administration, service level agreements, and additional curated course bundles.
  • WebAssign online homework. WebAssign is a commercial online homework system. It provides randomized homework custom-built to align with textbooks. Question sets have been created for this textbook which can be built into assessment sets by faculty. They provide support.
  • Videos. See the comments below for details.

Powerpoint slides are available on the book website, along with checkpoint quizzes and video solutions to the quizzes.

The MyOpenMath starter course includes overview videos and online homework
