## Description

The new 1st edition of Cynthia Young's*Precalculus*helps to bridge the gap between in-class work and homework by helping students overcome common learning barriers and build confidence in their ability to do mathematics. The text features unique, strong pedagogy and is written in a clear, single voice that speaks directly to students and mirrors how instructors communicate in lectures. In this text, Young enables students to become independent, successful learners by including multiple exercise types, more opportunities to use technology, and a themed modeling project that empowers students to apply what they have learned in the classroom to the world outside the classroom. The seamlessly integrated digital and print resources to accompany

*Precalculus*offer additional tools for both instructors and students in order to help students experience success.

*Precalculus* is suited for a 1 or 2 semester course and will focus on different learning styles. There will also be an emphasis on more challenging problems as well as streamlined prose to quicken the pace of the book.

**is an online teaching and learning environment that integrates the entire digital textbook with the most effective instructor and student resources to fit every learning style.**

__WileyPLUS__Organized around the essential activities you perform in class, ** WileyPLUS** helps you:

**Prepare and Present.**Create class presentations using a wealth of Wiley-provided resources, including an online version of the textbook, PowerPoint slides, animations, and more—making your preparation time more efficient. You may easily adapt, customize, and add to this content to meet the needs of your course.- Automate the assigning and grading of homework or quizzes by using Wiley-provided question banks or by writing your own. Student results will be automatically graded and recorded in your gradebook.
*WileyPLUS*can link homework problems to the relevant section of the online text, providing students with context-sensitive help. **Track Student Progress.**Keep track of your students’ progress via an instructor’s gradebook, which allows you to analyze individual and overall class results to determine student progress and level of understanding.**Administer Your Course.***WileyPLUS*can easily be integrated with other course management systems, gradebooks, or other resources you are using in your class, providing you with the flexibility to build your course in your own way.

**Clear, Concise and Inviting Writing**. The author’s engaging and clear presentation is presented in a layout that is designed to reduce math anxiety.**Preview to Calculus**exercises are found at the end of every section and chapter**Skills/Concepts Objectives**. Objectives are divided by skill and concept so students learn the difference between solving problems and understanding concepts.**Correct vs. Incorrect**. In addition to standard examples, some problems are worked both correctly and incorrectly to highlight common errors students make.**Catch the Mistake**. In every section, “Catch the Mistake” exercises put the students in the role of the instructor grading homework which increases the depth of understanding and reinforces what they have learned.**Your Turn**. Students are often asked to work a problem immediately following an example to reinforce and check their understanding; these are ideal for in-class activity and preparing the student to work homework later.**Parallel Words and Math**. This text reverses the common presentation of examples by placing the explanation in words on the left and the mathematics in parallel on the right. This makes it easier for students to read through examples as the material flows more naturally and as commonly presented in lecture.**Modeling Your World**: This feature is found at the end of every chapter. It uses real world data to model mathematical applications found in everyday life**Five Different Types of Exercises**. Every chapter has skill, application, catch the mistake, challenge and technology exercises. The exercises gradually increase in difficulty and vary skill and conceptual emphasis. The challenge exercises specifically focus on assessing conceptual understanding.**Review Chapter 0**. A review of equations and inequalities.**Chapter Introduction Flow Chart and Objectives**. A flow chart and chapter objectives give an overview of the chapter to help students see the big picture.**Chapter Review Chart**. A chapter review chart organizes the topics in an easy to use one-page layout. This feature includes key concepts and formulas, as well as indicating review exercises so that students can quickly summarize a chapter and study smarter.**Author Instructional Videos**. For review at home or for a class missed, each chapter has a video that includes an introduction and review. The author works some of the examples and “Your Turn” problems from the text on the videos as well.
