Algebra/Trig with Graphing CalculatorsMathematics

Designed for the Precalculus course covering Algebra and
Trigonometry. This text covers right angle trigonometry first and
then develops the unit circle approach. This text requires student
use of graphing calculators or a computer based software program. For
schools who wish to cover unit circle first, please see “Precalculus:
Graphing and Data Analysis”.
The goal of this text is to provide a solid mathematical foundation
via visualization of real world data. Technology is used as a tool
to solve problems, motivate concepts, explore and preview mathematical
concepts and to find curves of best fit to the data. Most mathematical
concepts are developed and illustrated both algebraically and graphically
 with the more intuitive and appropriate method presented first.
@BREAKNOLINALT = Mathematics
The authors use their extensive teaching and writing experiences
to guide and support students through the typical difficult areas.
Each section opens with the mathematical objectives of the
section. Each objective is referenced as it is encountered in the
section.
Examples are worked out stepbystep, both numerically and
in “English”.
Many examples include the “Now Work” feature which
suggests a similar oddnumbered problem from the section exercise
set. This allows for immediate reinforcement of concepts through
doing.
“Historical Notes” are provided in context, enhancing
student interest, provide anecdotal information on how and where mathematical
concepts have come from.
Exercises are carefully crafted — beginning with confidence
builders and visualization exercises, then practice and drill, followed
by the more challenging and application driven problems. Discussion,
Writing and Research questions are clearly called out by the red icon
in the margin.
Each chapter opens by listing the concepts (and page references)
that the student will need to review “Before Getting Started”.
The chapters conclude with a detailed chapter review, including
“Important Formulas, Theorems and Definitions”, a list of
“Things to Know and Do”, True/False Questions, FillintheBlank
items, and Review Exercises.
@BREAKNOLINALT = Technology
The authors approach the use of technology as an enhancement
to the learning of mathematics not as a replacement for learning.
Graphing utilities are used to help students analyze data
and find curves of best fit. Types of curve fitting discussed include:
linear, quadratic, cubic, power, exponential, logarithmic, logistic,
and sinusoidal.
Using the power of the grapher, students are able to approach
problems and concepts that may have been beyond them without the grapher.
Real TI83 screen shots are used as the illustrations for
the purpose of clear visualization of the materials.
@BREAKNOLINALT = Data
Sourced data connects the mathematical concepts to other
disciplines and other interests of the students  adding relevancy
and motivation.
Applications involving data analysis utilize real world
sources such as the US Census Bureau, Government Agencies and the
Internet.
Each chapter has an “Internet Exploration”. These
optional explorations introduce students to “live data” via
the Internet. Multiple questions follow each exploration encouraging
the use of Polya's problem solving strategies. The links to the sites
are all maintained via the Prentice Hall Companion Website for Sullivan
