"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."
— Fred M. Schifando, Pennsylvania State University
"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."
— Richard Riggs, New Jersey City University
"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."
— Greg S. Deitrich, Florida Community College at Jacksonville
"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."
— John Gosselin, University of Georgia
"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."
