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 right triangle 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.
