For courses in Precalculus   Precalculus: Graphical, Numerical, Algebraic — by the nationally recognised author team of Demana, Waits, Foley, Kennedy, and Bock—is the leading choice for graphing-intense courses. Now in its 9th Edition, this bestseller offers extremely accessible writing and exercises, a balanced approach to problem solving, the most appropriate use of technology, and an easier and more consistent transition from Precalculus to Calculus. A principal feature of this text is the balance among the algebraic, numerical, graphical, and verbal methods of representing problems: the rule of four.  This approach reinforces the idea that to understand a problem fully, students need to understand it algebraically as well as graphically and numerically.   The full text downloaded to your computer With eBooks you can: search for key concepts, words and phrases make highlights and notes as you study share your notes with friends eBooks are downloaded to your computer and accessible either offline through the Bookshelf (available as a free download), available online and also via the iPad and Android apps.
