Main Points

• Miami's Calculus textbook is Calculus: Early Transcendentals, 9th Edition by Stewart, Clegg, and Watson (Stewart 9e for short), published by Cengage.
• You only need to purchase one of the following options for a specific semester. If you will only be taking MTH 151, then Option 1 should be the most economical. (Due to bookstore markups, Option 1 may be more expensive at some locations.) However, if you will be taking multiple semesters of Calculus at Miami, you should purchase Option 2. If you have multiple courses, even in other departments, using a Cengage book this semester, you should also consider Option 2.
• MTH 151: WebAssign online homework and eBook is required for MTH 151. 
• MTH 249, 251, 252: WebAssign and eBook may be required for MTH 249, 251, 252 at the instructor's discretion.
• One code gives access to both WebAssign and the eBook. It is not possible to get a code just for one or the other.
• All buying options sold locally include WebAssign and eBook. If you purchase from an online seller, then it is your responsibility to make certain you have the correct book and have WebAssign access (if required).
• Codes should be purchased at local bookstores or direct from the publisher. See below for Where to Buy. Codes purchased elsewhere may or may not work.
• Students have free access for two weeks without a code.

Cengage Unlimited (Option 2)

• Cengage Unlimited is a digital subscription, giving you access to any of the Cengage eBooks and WebAssign online homework used in your courses.
• Do not purchase the Cengage Unlimited eTextbook ($69.99) option if your course requires WebAssign. You need the full $124.99 option. All sections of MTH 151 require WebAssign. Other Calculus may require WebAssign at the instructor's discretion.
• One price works for multiple courses in the same semester. For example, if you take MTH 151 and CSE 148 this semester, you only need one subscription.
• You only need a One Semester (4 month) subscription for your entire Calculus sequence. The subscription will carry over to future semesters of Calculus at no additional cost. (The name is misleading, but the 4 month works because Stewart 9e is used for all Calculus courses. You will need to resubscribe if you have non-Calculus courses in future semesters that use Cengage Unlimited.)
• There are three subscription options available: one semester (4 months), 12 month, and 24 month. Only buy the 12 or 24 month if you expect to take a non-Calculus Cengage Unlimited course in a future semester.
• Hard copies can be rented for a small fee. Purchase options are also available.
• See Cengage Unlimited for more details. See the Where to Buy links below for pricing.

Options by Course

• MTH 151 with no future Calculus - Options 1 is least expensive, though either option works. The codes in Option 1 will only work for one semester. You will not be able to access the eBook or WebAssign in future semesters.
• MTH 151 with more Calculus in the future - Option 2. The purchase of one semester of Cengage Unlimited will work for multiple terms with Stewart 9e. If you are concerned that you may need to retake MTH 151 due to withdrawal or insufficient grade, then Option 2 is also for you.
• MTH 249, 251, 252 - Options 1 or 2. The code in Option 1 will only work for one semester. You will not be able to access the eBook or WebAssign in future semesters if you choose Option 1. The purchase of one semester of Cengage Unlimited will work for multiple terms with Stewart 9e.

Buying Elsewhere

If you choose to buy a hard copy of Calculus: Early Transcendentals, 9th Edition by Stewart, Clegg, and Watson from another seller, you should know which chapters are covered in each course. As mentioned above, WebAssign codes purchased elsewhere might not work with Miami's system.
