## Overview

The Ratti/McWaters/Skrzypek series draws from the authors' extensive classroom experience to aid in conceptual understanding. Just-in-time review throughout College Algebra and Trigonometry, 4th Edition ensures that you'll grasp essential skills before being introduced to new concepts. Numerous applications encourage you to apply the concepts and skills you'll learn in college algebra and trigonometry to other courses (including the physical and biological sciences, engineering, economics, and to on-the-job and everyday problem solving). You will have many opportunities to think about important mathematical ideas, and to practice and apply algebraic skills. Because mathematical concepts are developed thoroughly and with clearly defined terminology, you will see the “why” behind those concepts, paving the way for a deeper understanding, less reliance on rote memorization and ultimately greater success.
