6/9   Extended Help-Study Hours

      We have been able to obtain the services of
      another TA, David Waite.  David will arrive
      in the Help-Study Room at about 2:30 and
      stay until 4:30 or until the last student
      leaves, whichever comes first.  David will
      also help to proctor the examinations.
      David's e-mail address is mrngstar@asu.edu.

6/21  In the HW for Jun 28, drop Problem 31 and
      add Problem 30.
