In the COMAP tradition, contemporary applications and mathematical modeling are presented in novel ways to help teach and motivate students. Throughout the text, students explore a number of essential concepts and develop important modeling, data analysis, and problem-solving skills necessary to prepare them for the future. College and high-school versions have different covers but the same content."Precalculus: Modeling Our World uses contemporary applications and mathematical modeling to teach and motivate students. Students learn to build, test, and present models that describe a variety of real-world situations, while activities throughout the text engage them in everyday problems that help illuminate mathematical principles. For example, the error correction capability of compact disk players demonstrates the importance of polynomials. Optional graphing calculator technology is integrated throughout the text and provides students with more opportunities to explore data graphically."
