Overview

Accessible to students and flexible for instructors, COLLEGE ALGEBRA, EIGHTH EDITION, incorporates the dynamic link between concepts and applications to bring mathematics to life. By integrating interactive learning techniques, the Aufmann author team helps students to better understand concepts, work independently, and obtain greater mathematical fluency. The Eighth Edition also includes technology features to accommodate courses that allow the option of using graphing calculators. Additional program components that support student success include tutorial practice, online homework, Live Online Tutoring, and Instructional DVDs. The authors' proven Aufmann Interactive Method allows students to try a skill as it is presented in example form. This interaction between the examples and Try Exercises serves as a checkpoint to students as they read the textbook, do their homework, or study a section. In the Eighth Edition, Review Notes are featured more prominently throughout the text to help students recognize the key prerequisite skills needed to understand new concepts.

Richard N. Aufmann, Palomar College

Richard Aufmann is the lead author of two bestselling developmental math series and a bestselling college algebra and trigonometry series, as well as several derivative math texts. He received a BA in mathematics from the University of California, Irvine, and an MA in mathematics from California State University, Long Beach. Mr. Aufmann taught math, computer science, and physics at Palomar College in California, where he was on the faculty for 28 years. His textbooks are highly recognized and respected among college mathematics professors. Today, Mr. Aufmann's professional interests include quantitative literacy, the developmental math curriculum, and the impact of technology on curriculum development.

Richard D. Nation, Palomar College

Richard Nation received a B.A. in mathematics from Morningside College and a M.S. degree in mathematics from the University of South Dakota. Mr. Nation also attended a National Science Foundation academic year institute in mathematics at San Diego State University. Mr. Nation taught math at Palomar College in California, where he was on the faculty for 20 years. He has over 38 years’ experience teaching mathematics at the high school and college levels. He is the co-author of several Aufmann titles. Today, Mr. Nation’s professional interests include the impact of technology on curriculum development and on the teaching of mathematics at the precalculus level.
  • NEW Concept Check Exercises - Each exercise set starts with exercises that are designed to test your students' understanding of new concepts.
  • NEW Enrichment Exercises - Each exercise set concludes with an exercise or exercises that are designed to extend the concepts presented in the section or to provide exercises that challenge your students' problem solving abilities.
  • NEW Interactive Demonstrations - New Interactive Demonstrations allow you to adjust parameters and immediately see the change produced by your adjustment. These Interactive Demonstrations run on computers and on mobile devices. Instructions for using each of the demonstrations are provided. You can access these Interactive Demonstrations by scanning a QR code, with a QR reader app, or by using the web address supplied in the directions.
  • NEW An Interactive Technology Approach via WolframAlpha - Several Integrating Technology features show how WolframAlpha can be used to perform computations, solve equations, graph functions, and find regression functions. WolframAlpha runs on computers and mobile devices. WolframAlpha often provides an alternative to the use of a graphing calculator. Access WolframAlpha by scanning a QR code or by using the address: www.wolframalpha.com.
  • Integrating Technology boxes show how technology can be used to illustrate concepts and solve many mathematical problems. Examples and exercises that require a calculator or a computer to find a solution are identified by the graphing calculator icon.
  • Modeling sections and exercises rely on the use of a graphing calculator or a computer. These optional sections and exercises introduce the idea of a mathematical model and help you see the relevance of mathematical concepts.
  • Chapter Review Exercise Sets and Chapter Tests, at the end of each chapter, are designed to provide you with another opportunity to assess your students' understanding of the concepts presented in a chapter. The answers for all exercises in the Chapter Review Exercise Sets and the Chapter Tests are provided in the Answers to Selected Exercises Appendix along with a reference to the section in which the concept was presented.
  • Mid-Chapter Quizzes help you assess students' understanding of the concepts studied earlier in the chapter. The answers for all exercises in the Mid-Chapter Quizzes are provided in the Answers to Selected Exercises Appendix, along with a reference to the section in which a particular concept was presented.
  • A Quantitative Reasoning feature demonstrates math solutions to real-world problems and is compliant with MAA Guidelines and AMATYC 2006 Crossroads Revisited.
  • Chapter Test Preps summarize the major concepts discussed in each chapter. These Test Preps help students prepare for a chapter test. For each concept there is a reference to a worked example illustrating the concept and at least one exercise in the Chapter Review Exercise Set relating to that concept.
  • Visualize the Solution, available with both algebraic and graphical solutions when appropriate, are provided to help students visualize the mathematics of the example and to create a link between the algebraic and visual components of a solution.
  • Exploring Concepts with Technology features appear after the last section in each chapter and provide you the option to use calculators or computers to solve computationally difficult problems. In addition, students are challenged to think about pitfalls that can be produced when using technology to solve mathematical problems.
