Overview

PRECALCULUS: REAL MATHEMATICS, REAL PEOPLE, 7th Edition, is an ideal student and instructor resource for courses that require the use of a graphing calculator. The quality and quantity of the exercises, combined with interesting applications and innovative resources, make teaching easier and help students succeed. Retaining the series' emphasis on student support, selected examples throughout the text include notations directing students to previous sections to review concepts and skills needed to master the material at hand. The book also achieves accessibility through careful writing and design—including examples with detailed solutions that begin and end on the same page, which maximizes readability. Similarly, side-by-side solutions show algebraic, graphical, and numerical representations of the mathematics and support a variety of learning styles. Reflecting its subtitle, this significant revision focuses more than ever on showing students the relevance of mathematics in their lives and future careers.

Ron Larson, The Pennsylvania State University, The Behrend College

Dr. Ron Larson is a professor of mathematics at The Pennsylvania State University, where he has taught since 1970. He received his Ph.D. in mathematics from the University of Colorado and is considered the pioneer of using multimedia to enhance the learning of mathematics, having authored over 30 software titles since 1990. Dr. Larson conducts numerous seminars and in-service workshops for math educators around the country about using computer technology as an instructional tool and motivational aid. He is the recipient of the 2014 William Holmes McGuffey Longevity Award for CALCULUS: EARLY TRANSCENDENTAL FUNCTIONS, the 2014 Text and Academic Authors Association TEXTY Award for PRECALCULUS, the 2012 William Holmes McGuffey Longevity Award for CALCULUS: AN APPLIED APPROACH, and the 1996 Text and Academic Authors Association TEXTY Award for INTERACTIVE CALCULUS (a complete text on CD-ROM that was the first mainstream college textbook to be offered on the Internet). Dr. Larson authors numerous textbooks including the best-selling Calculus series published by Cengage Learning.
  • New LarsonPrecalculus.com: This companion website offers free access to multiple tools and resources that supplement student learning. Students can view and listen to worked-out solutions of Checkpoint problems in English or Spanish, download data sets, explore examples, watch lesson videos, and much more.
  • New Chapter Opener: Each Chapter Opener highlights real-life applications used in the examples and exercises.
  • New How Do You See It?: The How Do You See It? feature in each section presents a real-life exercise that students solve by visual inspection using the concepts learned in the lesson. This exercise is excellent for classroom discussion or test preparation.
  • New Checkpoints: Accompanying every example, the Checkpoint problems encourage immediate practice and check students' understanding of the concepts presented in the example. Students can view and listen to worked-out solutions of the Checkpoint problems in English or Spanish at LarsonPrecalculus.com.
  • New Data Spreadsheets: Downloadable, editable spreadsheets from LarsonPrecalculus.com let students use the data to solve exercises.
  • Revised Exercise Sets: The exercise sets have been carefully and extensively examined to ensure they are rigorous and relevant and to include all topics our users have suggested. The exercises have been reorganized and titled so students can better see the connections between examples and exercises. Multi-step, real-life exercises reinforce problem-solving skills and mastery of concepts by giving students the opportunity to apply the concepts in real-life situations.
  • Revised Section Objectives: A bulleted list of learning objectives gives students the opportunity to preview what will be presented in the upcoming section.
  • Revised Remark: These hints and tips reinforce or expand upon concepts, help students learn how to study mathematics, address special cases, or show alternative or additional steps to a solution of an example.
  • Revised Remark: These hints and tips reinforce or expand upon concepts, help students learn how to study mathematics, address special cases, or show alternative or additional steps to a solution of an example.
  • Why You Should Learn It Exercise: An engaging real-life application of the concepts in the section. This application exercise is typically described in the section opener as a motivator for the section.
  • Library of Parent Functions: To facilitate familiarity with the basic functions, a Library of Parent Functions contains several elementary and non-elementary functions. Each function is introduced at the first point of use in the text with a definition and description of basic characteristics. The Library of Parent Functions Examples are identified in the title of the example and there is a Review of Library of Parent Functions after Chapter 4. A summary of functions is presented on the inside cover of this text.
  • Make a Decision Exercises: The Make a Decision exercises at the end of selected sections involve in-depth applied exercises in which the student will work with large, real-life data sets, often creating or analyzing models. These exercises are offered online at LarsonPrecalculus.com.
  • Explore the Concept: Each Explore the Concept engages students in active discovery of mathematical concepts, strengthens critical thinking skills, and helps build intuition.
  • What's Wrong: Each What's Wrong points out common errors made using graphing utilities.
  • Technology Tip: Technology Tips provide graphing calculator tips or provide alternate methods of solving a problem using a graphing utility.
  • Algebra of Calculus: Throughout the text, special emphasis is given to the algebraic techniques used in calculus. Algebra of calculus examples and exercises are integrated throughout the text.
  • Algebraic-Graphical-Numerical Exercises: These exercises allow students to solve a problem using multiple approaches: algebraic, graphical, and numerical. This helps students see that a problem can be solved in more than one way and that different methods yield the same result.
  • Modeling Data Exercises: These multi-part applications involve real-life data and offer students the opportunity to generate and analyze mathematical models.
  • Vocabulary and Concept Check: The Vocabulary and Concept Check appears at the beginning of the exercise set for each section. Each of these checks asks fill-in-the-blank, matching, and non-computational questions designed to help students learn mathematical terminology and to test basic understanding of that section's concepts.
  • What you should learn/Why you should learn it: These summarize important topics in the section and why they are important in math and life.
  • Chapter Summaries: The Chapter Summary includes explanations and examples of the objectives taught in the chapter.
  • Error Analysis: This exercise presents a sample solution that contains a common error, which the students are asked to identify.
  • Enhanced WebAssign: Enhanced WebAssign combines exceptional Precalculus context you know and love with the most powerful online homework solution, WebAssign. Enhanced WebAssign engages students with immediate feedback, rich tutorial content and interactive, fully customizable eBooks (YouBook) helping them develop a deeper conceptual understanding of the subject matter.
