Precalculus: concepts through functions, a unit circle approach to trigonometry (Pearson new international edition.)

Precalculus: Concepts through Functions, A Unit Circle Approach to Trigonometry, Second Edition embodies Sullivan/Sullivan’s hallmarks–accuracy, precision, depth, strong student support, and abundant exercises–while using functions as the unifying theme that ties the concepts together. To ensure that students master basic skills and develop the conceptual understanding they need for the course, this text focuses on the fundamentals: preparing for class, practicing their homework, and reviewing the concepts. After using this book, students will have a solid understanding of algebra and functions so that they are prepared for subsequent courses, such as finite mathematics, business mathematics, and engineering calculus.

In the Second Edition, the coverage of functions is even stronger, particularly in the first two chapters. This edition features Showcase Examples in a guided, step-by-step format, and “Model It” examples and exercises to help students develop the ability to build models. Exercise Sets at the end of each section are now classified so instructors can easily assign the most appropriate homework for their classes’ needs. The Chapter Test Prep Videos provide fully worked-out solutions to all chapter test exercises, and are now available on YouTube™, as well as on DVD and in MyMathLab®.
