Learning precalculus is easier with the visual emphasis in PRECALCULUS: WITH UNIT-CIRCLE TRIGONOMETRY, Fourth Edition and its accompanying technology tools. This textbook uses a graphical perspective throughout to provide a visual understanding of college algebra and trigonometry. David Cohen is known for his clear writing style, as well as the numerous quality exercises and applications he includes in his respected texts. In this new edition, graphs, visualization of data, and functions are introduced much earlier and receive greater emphasis. Many sections contain more examples and exercises involving applications and real-life data. The accompanying CD-ROM and online tutorials give you the practice you need to improve your grade in the course.
