Known for their ability to connect with students, acclaimed authors Sullivan and Sullivan focus on the fundamentals (preparing for class, practice with homework, reviewing key concepts), encouraging the conceptual understanding and mastery of basic skills you'll need for this and future courses. Part of the Concepts Through Functions Series, Precalculus: Concepts Through Functions, A Right Triangle Approach to Trigonometry introduces functions at the start and maintains a continuous theme by introducing and developing a new function in every chapter. Graphing utility coverage is optional and can be included at the instructor's discretion. In the 4th Edition, new Desmos© screen captures have been added throughout, reflecting that graphing technology expands beyond graphing calculators; updated Retain Your Knowledge problems improve your recall of concepts learned earlier in the course; and much more.
