Archive of Announcements for Math 427, Autumn 2012

This page contains all the announcements that have appeared on the Math 427 Homepage. [Date originally posted]

• [9/23] Here is Homework Assignment #1; a hard copy will be given out at the first class. This assignment will not be collected or graded, but instead will prepare you for a worksheet you will do on the second day of class, Wednesday, September 26. A substitute instructor, Professor Jim King, will supervise the worksheet.
  (Subsequent assignments usually will be available only on the website, not as hard copy. Homework Assignment #2 will be posted on the website soon, and will be due and collected on Wednesday, October 3.)
• [9/28] Volunteer Notetakers needed. Disability Resources for Students (DRS) is looking for a volunteer notetaker to assist a student who has a disability that impacts their ability to take notes in class. At least two notetakers are needed: a primary who would be able to copy their notes once a week, and an alternate who would be on standby as a back-up notetaker. DRS is also recruiting through email so there is a chance that one of you has already volunteered. However, in case no one has yet volunteered, please consider doing so as time is of the essence. The time commitment is minimal, but the difference it makes for the student is significant. DRS will pay for the photocopying and will provide a letter of recommendation for your volunteer hours.
  If you are interested in volunteering, or if you have any questions, please contact DRS for more information. They are located in Schmitz Hall, room 448. You may call DRS at 543-8924 or email them at uwdss@u.washington.edu. Thank you for your consideration.
• [9/28] Homework Assignment 2, due W 10/3: Reading: For the homework problems, you should read carefully everything up through §15. Lectures in Week 2 will also cover §§16-26 and possibly §§29-30. (We will come back to §§27-28 later, because they use a theorem from chapter 6.)
  There are a lot of computational problems you should do and check your final answer, but the details don't need to be graded. These will be assigned as "W" problems, because they are problems you should work, sometimes because they will be a warmup for a later problem, but they will not be collected or graded, so you don't need to write them up nicely to hand them in. Other problems will be labelled as "H" problems, to hand in to be graded.
  W problems for HW 2: (Don't panic, most of these are very short!) p. 5, #2; p. 8, #1ac (hint for c: polar form); p. 12, #2; pp. 14-15, #1bd,2b,5; p. 22, #1ab; pp. 29-31, #2b,8ab; p. 44, Make sure you understand the pictures in the appendix for #1 & 6.
  H problems for HW 2: p. 12, #3 - justify each step by reference to an equation in §4; p. 23, #6 and also give a counterexample to show the equation fails if Re(z) > 0 is replaced by Im(z) > 0 in the given conditions; p. 44, #7; p. 55, #5; and
  Problem E: Consider the mapping w = z².
  (a) Show that the image of a half line x ≥ 0, y = c > 0 is a half parabola.
  (b) Sketch the region x ≥ 0, 0 ≤ y ≤ 1 and its image under the mapping, labelling corresponding boundary points as in Appendix 2. Also include some of the half lines x ≥ 0, 0 < y = c < 1 and their images.
• [10/4] Homework Assignment 3, due W 10/10: Reading: Ch. 2 through §26, then Ch. 3 §§29-33.
  p. 56: W #10c; H #11.
  pp. 62-62: W #4,8; H #9.
  pp. 71-72: W #1d,2d*,3b,4b,7; H Problem F below and #8.
  *To see why the function in 2d is interesting, see (14) on p. 106.
  Problem F: Follow the instructions for #3 on p. 71 for the function f(z) = x³ + i3x²y.
  pp. 77-78: W #1b,2c,7; H #6.
  pp. 81-82: W #2,4; H #1c,3.
  p. 92: W #1,4,8a,10; H #8b,11.
  pp. 97-98: W #1,2ab,4,8; H 2c,5.
  QUIZ 1 on Friday, 10/12, will cover material through this assignment. More information to be posted.
• [10/8] Quiz 1 information.
• [10/10] Homework Assignment 4 is on the Homework information page, link below [on course homepage].
• [10/11] Sample quiz problem answers. Note that the quiz covers the first three homework assignments, and so does not include the material newly introduced yesterday (10/10). In particular, the quiz may include questions on the logarithm, but will not include questions on the complex trigonometric functions.
• [10/15] Midterm date will be Monday, Nov. 5.
  Quiz 1 score statistics, solutions, and comments.
• [10/21] PDL elevator warning: The C-wing (where the Math Dept. is) elevator is closed for renovation, probably for the rest of the quarter. There are now working elevators in both the A and B-wings.
  Homework assignment 5, and all assignments in the future, are on the Homework information page, link below.
• [11/1] Midterm information.
• [11/11] Midterm solutions and score stats, including information on how to estimate your course grade based on work to date.
• [11/13] ANNOUNCEMENT: If your multipage homework paper is not STAPLED together, only the first sheet is sure to be graded (especially if you are a repeat offender for not stapling.)
• [11/17] Quiz 2 will be on Friday, November 30, and will cover topics from chapters 5 & 6. Notes allowed. Sample problems will be posted by Nov. 26.
