Precalculus: Concepts Through Functions, A Right Triangle Approach to Trigonometry introduces functions at the beginning of the text, then introduces and develops a new function in every chapter. Known for connecting with students, esteemed authors Sullivan and Sullivan focus on the fundamentals (preparing for class, practicing with homework, and reviewing key concepts), which encourages you to master basic skills and develop the conceptual understanding needed for this and future courses. Graphing utility coverage is optional and can be adjusted for different course needs. The 5th Edition offers abundant new and updated features including new Challenge Problems, new Interactive Figure Exercises, and much more.
