This page lists the options for purchasing a textbook and online HW system. The 15th edition etext and the HW system is provided free of charge from our class Canvas page. The instructions for accessing the etext and the HW system are now provided by Pearson. Here is that link: How to Access the HW System with Etext During the sign-up process, you will be prompted to enter your ASU Posting ID. Be sure to enter your correct ASU Posting ID, which is 4 digits, followed by a hyphen, followed by 3 digits. If you do not enter the correct ASU Posting ID, you will never get credit for your work at Mastering Physics. What if I don't know my ASU Posting ID? Once you are within the HW System, access the etext by selected Pearson eText from the menu on the left-hand side of the page. If you would like a hardcopy textbook, then THE LOOSELEAF EDITION OF OUR TEXTBOOK IS STRONGLY RECOMMENDED. Once you are inside your MP account for our class, then select "eText" from the menu on the left-hand border. The resulting eText page then gives you the opportunity to purchase the unbound edition for $50 with free ground shipping. The shipping may take two weeks, so purchase your looseleaf edition as soon as possible. Until it arrives, just read from the etext provided by MP. Once your looseleaf edition arrives, I suggest putting it into three separate 3-ring binders, one for Mechanics (121), one for E&M (131), and one for Thermodynamics and Modern Physics. I also suggest that you get a small 3-ring binder, suitable for one chapter at a time. Bring this small binder with you to class, and make notes in the margins when questions that you have about the reading are answered during our lecture class. Thanks much. GBA
