# Precalculus: Modeling Our World 2nd Edition (Teachers Edition) (CD-Rom)

Click Here To Preview Precalculus: Modeling Our World

This is a different precalculus text. It contains all of the topics that you would expect to find in a precalculus text and more; but it is a text written by COMAP and applications is our middle name. Thus you will see the concepts and skills of precalculus presented from an applications and modeling point of view. Moreover, this is an activity and problem-solving based book. We want students to experience the mathematics they are learning in a way that will make both the mathematics and the contemporary applications come alive.

We make serious use of graphing calculators and a variety of software, including spreadsheets and geometric utility programs. We introduce and make use of data analysis techniques. All of which permit us to analyze deeper and more meaningful problems. And we have attempted to add material that will in fact, as well as name, better prepare students for their work in calculus€”from our introductory work on functions to our final chapter on finite difference equations. We use a spiraling approach, coming back to earlier ideas in later chapters, so that we can keep those ideas, concepts, and skills alive, reinforcing their importance as well as providing additional practice. **New Features of the second edition:**

- The first full-color edition.
- Updated data and news articles throughout.
- Correlation to the Common Core State Standards.
- A single electronic teacher disc that includes the student text in PDF format as well as answers, teacher notes, blackline masters, software, and test questions.
- A supplemental chapter on probability will be available separately or as an eleventh chapter through custom publishing.
- Student materials are available in CD-ROM, Print and Webportal.
