**Precalculus: A Right-Triangle Approach** helps you prepare, visualize and ultimately succeed in your precalculus course. You'll learn to “see the math” through a focus on visualization and early introduction to functions, which allows for the use of graphs to provide a visual aspect to solving equations and inequalities. Specific features help you visualize and make connections between concepts. The **5th Edition** expands and enhances instruction on review topics needed for corequisite courses or simply for students who start the course needing additional preparation. Ongoing review features throughout reinforce the concepts and help build understanding.
