For courses in Precalculus.

Adapts to contemporary students’ varying needs

The proven approach of Sullivan and Sullivan focuses students on the fundamental skills of the course: prepare for class, practice with homework, and review the concepts.  Precalculus: Enhanced with Graphing Utilities fully integrates graphing utilities into topics, allowing students to explore mathematical concepts and encounter ideas usually studied in later courses. Many examples show solutions using algebra side by side with graphing techniques. The text features a review chapter before covering the traditional precalculus topics of functions and their graphs, polynomial and rational functions, and exponential and logarithmic functions. The trigonometric functions are introduced using a unit circle approach and show how it is related to the right triangle approach.

The 9th Edition is revised and refined throughout, with updated Desmos and screen captures as well as TI-84 Plus CE screens; updates exercise sets with timely and relevant scenarios; adds a new Highlighting Contemporary Mathematicians feature, and much more.
