Course Materials

Textbook

Precalculus by Michael Sullivan, 11th edition, published by Pearson/Prentice Hall.

Note that a MyLab Math code is required for this course while the printed textbook is optional.

MyLab Math

A MyLab Math code linked to your Blackboard account is required for this course.  To ensure your MyLab Math code is properly linked to your blackboard account you should purchase your MyLab Math code through the link in Blackboard.  Your MyLab Math code will include an electronic version of the textbook, buying a print copy is optional.

If you wish to buy a printed copy of the textbook, a bundle including both the the printed textbook and MyLab Math access code is available from the UIC Bookstore.  You may instead wish to purchase a MyLab Math code via the link in Blackboard and buy a used textbook.

If you purchase your access code in any other manner than following the link in blackboard, be sure not to use this access code for any other purpose before you link your Blackboard account to your MyLab Math account.
