You only need one of the following books. The first book covers the full calculus sequence, and the second only has the chapters we will cover in this class. The second book below is just a bound version of chapters 10-14 of the first book. The Full calculus version should be available in the bookstore. You can also rent an electronic version online at http://www.cengagebrain.com/tl1/en/US/storefront/US?cmd=catProductDetail&ISBN=0-618-60624-6 (you can either rent the entire book or just specific chapters).
This is the official book for the course. It was used at Drake for Calculus 1 and Calculus 2, so you may not need to buy it if you already have this book from those classes.
