As the best seller in its field, Precalculus Functions and Graphs: A Graphing Approach, is the choice for precalculus courses that require students to use graphing technology, begin with a faster paced algebra review, and introduce trigonometry first with a unit circle approach, then the right triangle. The Third Edition offers both instructors and students a more solid, comprehensive, and flexible program than ever before.For a complete listing of features, see Larson/Hostetler/Edwards, College Algebra: A Graphing Approach, 3/e.
