PRECALCULUS prepares students for calculus and the rigors of that course, having been written by teachers who have taught the courses and seen where students need help--and where other texts have come up short. The text features precise definitions and exposition, carefully crafted pedagogy, and a strong emphasis on algebraic, transcendental, and trigonometric functions. To show students how important and relevant precalculus topics are to their future coursework, an optional Looking Ahead to Calculus feature appears in each chapter. The varied examples and exercises include many that encourage students to use and understand graphs, as opposed to simply draw them, providing additional sound preparation for calculus.

Karla Neal, Louisiana State University

Karla Neal received two degrees in mathematics from Louisiana State University and has been an instructor in the department of Mathematics for 31 years. During that time, she has served as the coordinator for College Trigonometry for more than 15 years. She has received three campus-wide teaching awards, and has served as a faculty advisor for several Christian campus organizations. Karla is an avid fan of the LSU Tigers. When she is not on campus, she is very active in her church, Healing Place Church in Baton Rouge, and can often be found on the golf course. At home, there are two dogs, Winston and Josie, waiting patiently.

R. David Gustafson, Rock Valley College (Emeritus)

R. David Gustafson is Professor Emeritus of Mathematics at Rock Valley College in Illinois and has also taught extensively at Rockford College and Beloit College. He is coauthor of several best-selling mathematics textbooks, including Gustafson/Frisk/Hughes' COLLEGE ALGEBRA, Gustafson/Karr/Massey's BEGINNING ALGEBRA, INTERMEDIATE ALGEBRA, BEGINNING AND INTERMEDIATE ALGEBRA, BEGINNING AND INTERMEDIATE ALGEBRA: A COMBINED APPROACH, and the Tussy/Gustafson and Tussy/Gustafson/Koenig developmental mathematics series. His numerous professional honors include Rock Valley Teacher of the Year and Rockford's Outstanding Educator of the Year. He has been very active in AMATYC as a Midwest Vice-president and has been President of IMACC, AMATYC's Illinois affiliate. He earned a Master of Arts from Rockford College in Illinois, as well as a Master of Science from Northern Illinois University.

Jeff Hughes, Hinds Community College

Jeff Hughes has taught the college algebra course continually for the past 20 years, and his firsthand experience with students lends itself to the innovative ideas he has brought to the text. He has led the way for the addition of the new features and the revised content in COLLEGE ALGEBRA, 10E. He teaches at Hinds Community College in Mississippi.
  • LOOKING AHEAD TO CALCULUS: Offering an interesting glimpse into calculus, this feature demonstrates the relevance of precalculus topics to students' future success. Each feature (placed at the end of the chapter to allow instructional flexibility) includes objectives referencing the related chapter material, discussion of the topics, and "Connect to Calculus" exercises. References to this optional material (highlighted so that instructors may teach or skip it at their discretion) appear throughout each chapter, reinforcing the connection between the topics at hand and future courses.
  • TITLED EXAMPLES: Descriptive titles have been added to clearly identify the topic and purpose of each example.
  • EXAMPLE STRUCTURE: To help students gain a deeper understanding of how to solve each problem, solutions begin with a stated approach. The examples are engaging and step-by-step solutions with annotations are provided.
  • SELF CHECKS: Each example is followed immediately by a Self Check exercise that actively reinforces student understanding of concepts and example solutions. The answers for students are offered at the end of each section. To assist instructors, the answers appear next to the problem in the Annotated Instructor's Edition, printed in blue.
  • NOW TRY EXERCISES: A reference to a Now Try exercise follows all Examples and Self Check problems, providing students an additional opportunity to assess their understanding of the concept related to each worked example. These references also show students a correspondence between the examples in the book and the exercise sets.
  • APPLICATION EXAMPLES: Applications from a wide range of disciplines demonstrate how mathematics is used to solve real problems, answering the student question, "When will I ever use this math?" These applications, many accompanied by an eye-catching photo, motivate the material and help students become better problem solvers.
  • GETTING READY EXERCISES: Each problem set begins with Getting Ready exercises, which test students' understanding of concepts and proper use of mathematical vocabulary. Students should be able to answer these fill-in-the blank questions before moving on to the Practice exercises.
  • COMPREHENSIVE EXERCISE SETS: To improve mathematical skills and cement understanding, the exercise sets progress from routine to more challenging. The mathematics in each exercise set is sound, but not so rigorous that it will confuse students. All exercise sets include Getting Ready, Practice, Application, and Discovery and Writing problems.
  • INTERESTING AND CONTEMPORARY APPLICATION EXERCISES: Application exercises, all with titles, reflect the book's emphasis on solving problems through realistic applications,
  • CHAPTER REVIEWS AND CHAPTER TESTS: Each chapter closes with a Chapter Review and Chapter Test, giving students the best opportunity for study and exam preparation. Chapter Reviews are comprehensive and consist of three parts: definitions and concepts, examples, and review exercises. Chapter Tests cover all the important topics and yet are brief enough to emulate a "real-time" test, so students can practice not only the math but also their test-taking aptitude. As an additional quick reference, endpapers offer the important formulas and graphs developed in the book.
  • ACCENTS ON TECHNOLOGY AND CALCULATORS: Accents on Technology appear throughout the textbook to encourage students to become intelligent users of technology and grasp concepts graphically. They illustrate and guide the use of a TI-84 graphing calculator for specific problems. Although graphing calculators are incorporated into the book, their use is not required. All graphing topics are fully discussed in traditional ways.
  • CAREERS IN MATHEMATICS CHAPTER OPENERS: To encourage students to explore careers that use mathematics and make a connection between math and real life, each chapter opens with Careers in Mathematics. New, exciting careers are showcased in this edition. Featuring information taken primarily from the Occupational Outlook Handbook, these snapshots include information on how professionals use math in their work and who employs them. A web address is provided, allowing students to learn more about the career.
  • SECTION OPENERS: Each section begins with a contemporary photo and a real-life application that will appeal to students of varied interests, piquing interest and motivating students to read the material.
  • NUMBERED OBJECTIVES: Numbered learning objectives, which are listed at the beginning of each section and appear as subheadings in the section, keep students focused.
  • STUDENT-FRIENDLY WRITING STYLE: Clear, concise, and friendly exposition helps to alleviate student anxiety about reading a mathematics textbook. The writing is informal yet accurate. Students and instructors alike should find the reading both interesting and inviting.
  • STRATEGY BOXES: To enable students to build on their mathematical reasoning and approach problems with confidence, Strategy boxes offer problem-solving techniques and steps at appropriate points in the material.
  • CAUTION BOXES: Caution boxes appear throughout the text to alert students to common errors and misunderstandings, and reinforce correct mathematics.
  • COMMENTS: Comment boxes appear throughout the textbook, providing additional insights; for instance, clarification on a specific step or concept in an example, or a tip for studying the material.
