Announcements

If you prefer, you can email your homework solutions to the grader (Eric). See above for his email address. Your homework should be received no later than the beginning of class (8:30am PST) on the due date.
If you have not already done so, please sign the release statement. If you do not want to give permission, then write "do not" above the word "give". Please either give the signed statement to me in class, or send me a pdf copy by email.
Note that there is extra reading FTA for 1/13/23 listed among the materials for the second homework.
The solutions to the Homework below are selected by the grader from student solutions. In some cases the answers are incomplete. For example in problems B and C on HW8, the solutions appear to assume that you can extend the functions continuously to the unit circle, which requires proof. I gave two solutions to problem B in class on Friday, which did not require proving a continuous extension, but rather only a proof that the absolute value tends to 1. The solution to Problem C can be easily modified to use just this fact (which occurs by assumption), instead of a continuous extension of the function itself. If you need a written version of those proofs, let me know via email and I will type them up on Monday.

Schedule of Homeworks and exams

As part of your homework, before each class meeting, read the next section in the text and bring any questions you might have to the discussion in class.

Written homework is to be handed in approximately once a week as described below. I suggest that you try the appropriate homework problems after reading the related material so that you can ask any questions you might have before you are required to turn in the homework.

Because the rate at which we cover this material is partly dependent upon discussions in class, I reserve the right to change the homework material and dates as well as the dates of the midterm exams as the quarter progresses.
