Preface
This Instructor’s Resource G uide for Discrete Mathematics and Its Applications, eighth edition, consists of five
items that an instructor of a course in discrete mathematics using the text should find useful.
• The bulk of this Guide consists of solutions to all the even-numbered exercises in the text, and thus com-
plements the Student’s Solutions Guide for Discrete Mathematics and Its Applications, eighth edition, which
contains solutions to the odd-numbered exercises. It is assumed that the user of the present manual has
access to that Guide as well. The solutions presented here are not necessarily the only ways of solving these
problems, of course, nor are the answers unique in all cases. These are complete solutions, although they are
somewhat less expository than the student-oriented solutions in the Student’s Solutions Guide.
• Several detailed course outlines are shown, for courses with different emphases and different student back-
grounds and ability levels. These suggested syllabi include courses with a mathematics emphasis, courses
with a computer science emphasis, one-term courses, and two-term courses.
• This Guide contains detailed teaching suggestions for instructors. There are chapter overviews, followed by
remarks on each section. Goals and prerequisites are stated, advice on teaching the section is offered, and
comments on the exercise sets are presented.
• Two sample tests are provided for each chapter and two sample final examinations—the first easier than the
second in each case. Solutions for the test questions are included. Instructors can draw on these sample tests
when constructing tests for their own classes, or they can provide them to students as samples with which
to prepare for the actual exams.
• Finally, this Guide contains a test bank of more than a thousand exam questions. Answers are included.
In addition to this Guide, you will find the companion website created for Discrete Mathematics and Its Appli-
cations an invaluable resource. Included here are a Web Resources Guide with links to external websites keyed
to the textbook, numerous Extra Examples to reinforce important topics, Interactive Demonstration Applets for
exploring key algorithms, Self Assessment question banks to gauge student understanding of core concepts, and
many helpful resources instructors can use for in-class teaching and homework assignments. See the section titled
“The Companion Website” on page xvi of the textbook for more details. The address is www.mhhe.com/rosen.
I want to thank Jerry Grossman for his extensive advice and assistance in the preparation of this Guide, Paul
Lorczak, Georgia Mederer, Lyndon Weberg, and Suzanne Zeitman for double-checking the solutions, and students
at Monmouth College and Oakland University for their input on preliminary versions of solutions to the exercises.
The test bank was produced by John Michaels, for whose excellent work I am most grateful. Some questions and
answers for this bank were contributed by Tao Jiang, Nancy Kinnersley, Antonette Logar, Thomas Roe, Zoltan
Szekely, and Bharti Temkin, to whom I also extend my appreciation.
It is possible that there are a few errors here, despite our best efforts at eliminating them. I would appreciate
hearing about all that you find, be they typographical or mathematical. Any other comments that will improve
subsequent editions of this book are always greatly appreciated. You can reach me using the Reporting of Errata
link on the companion website at www.mhhe.com/rosen.
