Precalculus: Concepts Through Functions, A Unit Circle Approach to Trigonometry

This new text embodies Sullivan/Sullivan’s hallmarks –  accuracy, precision, depth, strong student support, and abundant exercises while exposing students early (Chapter One) to the study of functions and taking a unit circle approach to trigonometry. "IT WORKS" for instructors and students because it focuses students on the fundamentals:preparing for class, practicing their homework, and reviewing. After completing the book, students will be prepared to handle the algebra found in subsequent courses such as finite mathematics, business mathematics, and engineering calculus and will have a solid understanding of the concept of a function.
