The textbook will be Linear Algebra and its Applications (fourth edition) by David C. Lay (Pearson/Addison Wesley, 2012, ISBN-10: 0321385179, ISBN-13: 9780321385178). This is the same textbook as used in recent semesters at Clarkson.
There is also a Study Guide available, containing additional information that many students find helpful: more detailed problem solutions, comments on the reading, hints about how to simplify some of the calculations, answers (almost!) to the true/false questions (which will play an important role in the class--in homework, quizzes, and exams), reviews of all of the key concepts, etc. You don't need to buy it, but I think you'll find it helpful. The bookstore will bundle it with the textbook if it can be done at minimal cost.
