James Stewart, author of the best-selling calculus textbook series, and his coauthors Lothar Redlin and Saleem Watson, wrote TRIGONOMETRY to address a problem they frequently saw in their classrooms: Students who attempted to memorize facts and mimic examples—and who were not prepared to "think mathematically." With this text, Stewart, Redlin and Watson help students learn to think mathematically and develop true, lasting problem-solving skills. Patient, clear, and accurate, TRIGONOMETRY consistently illustrates how useful and applicable trigonometry is to real life.
