Textbooks
This quarter, we have several optional textbooks. You do not have to buy any of them, and we, in fact, recommend that you not buy or use all of them.

Rosen. Discrete Mathematics and Its Applications. ISBN 0072899050
This textbook might be helpful for the first six weeks of the course. It does not have the content for the second half of the course.
If you do decide to buy this textbook, we strongly recommend that you buy an old edition. None of the homework problems will come from
the textbook, and the content is much the same from edition to edition.

Velleman. How To Prove It. ISBN 0521675995
This textbook might be helpful for the proofs portion of the course. We have found that students who struggle with proofs find this book to
be incredibly helpful. It has extra exercises (many of which are very good) and stepbystep explanations about how to write proofs. We recommend
you wait to buy this book until we get to the proofs section of the course, and then only buy it if you want extra explanations.
Books on Reserve at the Library
A small number of copies of our textbook may be available from the Engineering library or the Odegaard library on campus. You might be able to check them out for short periods to work on problems, but this may not be a reliable strategy longterm as your only access to a textbook. See
this link.
