#$&* course Mth 173 1/5 4I have Calculus Single Variable 5th edition. The bookstore has the 6th edition listed for this class. Will I be able to use the 5th edition? I have, so far, began the course introduction and requested access code and hope to find information about course text as well as other information that I am unaware of. I am using XP and Vista and using a desktop and laptop for devices.
