Precalculus: With Unit Circle Trigonometry (With Interactive Video Skillbuilder Cd-Rom) (Available 2010 Titles Enhanced Web Assign)

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.Review"The quantity and quality of the exercises are the reasons why I think that Cohen?s book is my favorite algebra and precalculus book ever?. Both the quantity and quality of the exercises of Cohen?s book are first class and the problems in each section are reflective of the concepts being taught. As far as I am concerned, the quality of both his algebra text and precalculus text are way above anything on the market that I?ve seen.""The mini projects are excellent and can be used for collaborative learning?. I think the writing style of an already well-written book has been improved.""This text is one of the most challenging precalculus books I have seen, but I like that because it gives students the opportunity to be very well prepared for calculus. The presentations are rigorous, precise, and detailed, but written in a way that students can follow fairly well. The exercises range from simple to complex and include not only applications to other disciplines but to other areas of mathematics as well." "One of the main reasons I continue to use this author?s texts is that I receive more compliments from my students on his books than I have on any other texts.""Overall, the quantity and quality of the exercises in Cohen?s texts are outstanding. The different levels of exercises--A, B, and C levels--make an excellent transition from skill development to concept development.""One of the strengths of the series has been David?s ability to make simple, clear, and reasoned arguments about the mathematical assertions?. David did a very subtle and powerful thing when he included difficult problems broken down into small, manageable steps." "The new authors have done a nice job in reorganizing the material in Chapter 6. Instructors familiar with earlier editions of Cohen?s books will find the transition seamless."About the AuthorDavid Cohen, a senior lecturer at UCLA, was the original author of the successful, well-respected precalculus series--COLLEGE ALGEBRA, ALGEBRA AND TRIGONOMETRY, PRECALCULUS: A PROBLEMS-ORIENTED APPROACH, and PRECALCULUS: WITH UNIT CIRCLE TRIGONOMETRY.
