many exercises that are designed to develop the student’s ability to generate and analyze
mathematicalcurvesandsurfaces.
Quick Check Exercises Eachexercisesetbeginswithapproximatelyfiveexercises
(answers included) that are designed to provide students with an immediate assessment
of whether they have mastered key ideas from the section. They require a minimum of
computationandareansweredbyfillingintheblanks.
FocusonConceptsExercises Eachexercisesetcontainsaclearlyidentifiedgroup
ofproblemsthatfocusonthemainideasofthesection.
TechnologyExercises Mostsectionsincludeexercisesthataredesignedtobesolved
using either a graphing calculator or a computer algebra system such as Mathematica,
Maple,ortheopensourceprogramSage. Theseexercisesaremarkedwithaniconforeasy
identification.
Applicability of Calculus One of the primary goals of this text is to link calculus
to the real world and the student’s own experience. This theme is carried through in the
examplesandexercises.
Career Preparation Thistextiswrittenatamathematicallevelthatwillpreparestu-
dentsforawidevarietyofcareersthatrequireasoundmathematicsbackground,including
engineering,thevarioussciences,andbusiness.
Trigonometry Review Deficiencies in trigonometry plague many students, so we
haveincludedasubstantialtrigonometryreviewinAppendixB.
Appendix on Polynomial Equations Becausemanycalculusstudentsareweak
insolvingpolynomialequations,wehaveincludedanappendix(AppendixC)thatreviews
theFactorTheorem,theRemainderTheorem,andproceduresforfindingrationalroots.
Principles of Integral Evaluation The traditional Techniques of Integration is
entitled “Principles of Integral Evaluation” to reflect its more modern approach to the
material. Thechapteremphasizesgeneralmethodsandtheroleoftechnologyratherthan
