Precalculus with Graphing CalculatorsMathematics

Varberg and Varberg use the graphics calculator throughout this text
to (1) help motivate and explain standard material, (2) explore concepts
that transcend the traditional precalculus course, and (3) make mathematics
come alive.
covers traditional topics, emphasizing those that are needed
in other mathematics, science or business courses or applications
and can be explored or illustrated on a graphics calculator.
organizes coverage around a particular function and its
graph, studying functions to a depth that includes:
 finding their zeros
 discovering where they increase and decrease
 identifying their maxima and minima
 analyzing their asymptotic behavior
 calculating their rates of change
each section begins with a Teaser problem and ends
with an extensive problem set composed of two parts:
 Part A—Skills and Techniques—offers simpler
problem pairs which follow the text and its examples closely
 Part B—Applications and Extensions—includes
a variety of more demanding problems that make use of the skills learned
in Part A in the broad context of mathematical, scientific and business
applications
contains sixty sections designed to be covered in one lesson,
leaving plenty of material for a one or twosemester course.
delays the discussion of graphics calculator programming
until the last chapter of the book where it fits naturally with the
discussion of sequences and series.
