Educators know that the more students can see, hear, and experience class resources,
the better they learn. With Tegrity Campus, students quickly recall key moments by using
Tegrity Campus’s unique search feature. This search helps students efficiently find what they
need, when they need it across an entire semester of class recordings. Help turn all your
students’ study time into learning moments immediately supported by your lecture.

Student Solutions Manual Prepared by Fred Safier of City College of San Francisco,
the Student’s Solutions Manual provides complete worked-out solutions to odd-numbered
exercises from the text. The procedures followed in the solutions in the manual match
exactly those shown in worked examples in the text.
Lecture and Exercise Videos The video series is based on exercises from the textbook.
J. D. Herdlick of St. Louis Community College-Meramec introduces essential definitions,
theorems, formulas, and problem-solving procedures. Professor Herdlick then works through
selected problems from the textbook, following the solution methodologies employed by the
authors. The video series is available on DVD or online as part of MathZone. The DVDs
are closed-captioned for the hearing impaired, subtitled in Spanish, and meet the Americans
with Disabilities Act Standards for Accessible Design.
NetTutor Available through MathZone, NetTutor is a revolutionary system that enables
students to interact with a live tutor over the web. NetTutor’s web-based, graphical chat capabilities
enable students and tutors to use mathematical notation and even to draw graphs as
they work through a problem together. Students can also submit questions and receive
answers, browse previously answered questions, and view previous sessions. Tutors are
familiar with the textbook’s objectives and problem-solving styles.
Computerized Test Bank (CTB) Online Available through the book’s website, this computerized
test bank, utilizing Brownstone Diploma ® algorithm-based testing software,
enables users to create customized exams quickly. This user-friendly program enables
instructors to search for questions by topic, format, or difficulty level; to edit existing questions
or to add new ones; and to scramble questions and answer keys for multiple versions
of the same test. Hundreds of text-specific open-ended and multiple-choice questions are
included in the question bank. Sample chapter tests and a sample final exam in Microsoft
Word ® and PDF formats are also provided.
