            Professor Ziegler will maintain his regular, posted office hours in which students can meet with him in person. In addition, students can e-mail questions to Professor Ziegler ( about the lectures and homework assignments. All e-mail queries will be answered in a timely fashion. (This can take up to 72 hours or more.)


            Homework will be assigned from each chapter covered in the text. Solutions for the assigned problems are available on Professor Ziegler’s web site for this course.

            Timely completion of assigned homework is essential for doing well in this class!

The date, time, and place of each of the two exams will be e-mailed to you as well as posted on Professor Ziegler’s web site for this course. Students must be able to come in person to take the examinations on the scheduled dates. There will be no make-up exams. A valid ID must be shown for entry to take each exam.
