,To the Student
As you begin, you may feel anxious about the number of theorems, definitions,
procedures, and equations. You may wonder if you can learn it all in time. Don’t
worry–your concerns are normal. This textbook was written with you in mind. If you
attend class, work hard, and read and study this text, you will build the knowledge
and skills you need to be successful. Here’s how you can use the text to your benefit.
Read Carefully
When you get busy, it’s easy to skip reading and go right to the problems. Don’t …
the text has a large number of examples and clear explanations to help you break
down the mathematics into easy-to-understand steps. Reading will provide you with
a clearer understanding, beyond simple memorization. Read before class (not after)
so you can ask questions about anything you didn’t understand. You’ll be amazed at
how much more you’ll get out of class if you do this.
Use the Features
I use many different methods in the classroom to communicate. Those methods,
when incorporated into the text, are called “features.” The features serve many
purposes, from providing timely review of material you learned before (just when
you need it) to providing organized review sessions to help you prepare for quizzes
and tests. Take advantage of the features and you will master the material.
To make this easier, we’ve provided a brief guide to getting the most from
this text. Refer to “Prepare for Class,” “Practice,” and “Review” at the front of the
text. Spend fifteen minutes reviewing the guide and familiarizing yourself with the
features by flipping to the page numbers provided. Then, as you read, use them. This
is the best way to make the most of your text.
Please do not hesitate to contact me through Pearson, with any q uestions,
comments, or suggestions for improving this text. I look forward to hearing from
you, and good luck with all of your studies.
Best Wishes!
