description: David Cohen's PRECALCULUS WITH UNIT-CIRCLE TRIGONOMETRY Fourth Edition focuses on teaching mathematics using a graphical perspective throughout to provide a visual understanding of college algebra and trigonometry. The author is known for his clear writing style and the numerous quality exercises and applications he includes in his respected texts. In this new edition graphs visualization of data and functions are now introduced much earlier and receive greater emphasis. Many sections now contain more examples and exercises involving applications and real-life data. While this edition takes the existence of the graphing calculator for granted the material is arranged so that one can teach the course with as much or as little graphing utility work as he/she wishes.
