Trigonometry, Trigonometry, and Precalculus.
A proven motivator for students of diverse mathematical backgrounds,
this text explores mathematics within the context of reallife, using
understandable, realistic applications consistent with the abilities
of any student. Graphing techniques are emphasized, including a thorough
discussion of polynomial, rational, exponential, and logarithmic functions
and conics. The use of a graphing calculator is optional.
NEW—Reorganized content.
 Presents material logically, and as needed, enabling
students to more easily grasp concepts and retain what they have learned.
NEW—Many new exercises and examples.
 Shows students how to utilize real data in table form.
NEW—Section Objectives.
 Identifies learning goals for students at the start of
each section so that they can organize their studies.
NEW—Internet Excursion begins each chapter.
 Provides students with a realworld problem that can
be analyzed using the material found in the chapter and information
found on the World Wide Web.
NEW—New design—Utilizes multiple
colors.
 Highlights important concepts for students.
Multiple source applications—Drawn from tax tables;
the Guinness Book of World Records; newspaper articles; and texts
in economics, chemistry, etc.
 Allows students to make the connection between familiar
situations and the learned math concepts.
Historical Notes—Presented in context.
 Gives students anecdotal information and compare techniques
to enhance their interest in related material.
Numerous graduated examples and exercises—Many
of which are applied.

“Calculator icon”—Designates selected
examples.
 Invites students to use a graphing calculator for checking
or exploration when appropriate.
“Now Work Problem xx” icon.
 Encourages students to pause and work an exercise problem
to ensure the previous concept was understood before moving on.
Review list and overview opens each chapter.
 Familiarizes students with an inventory of pertinent
material to be reviewed before getting started, and an often historically
based profile of the chapter concepts.
Detailed review closes each chapter—Includes important
formulas; theorems and definitions; a “things to know” list;
true/false and fillintheblank items; and review exercises.
