WEBWORK:       We will use webwork. It is located at http://webwork.math.ucsb.edu   The username and password has
                                 been sent to you already. If you did not receive it that means you are either not registered officially, or you
                                 have registered later, or you are not using your official e-mail address. In either case, please let me know.
                                 I encourage you to use university accounts in webwork, instead of  yahoo, hotmail, aol, etc.

                                 It is your responsibility to check the webwork and do homework problems there before the deadline.
 

     MIDTERM:     February 07. In class.
                                No books, notecards or calculators allowed. Please bring ID and big bluebook.
