## Math 324D Winter 2017

Welcome to our M324 course page. Here you can find announcements, the course calendar, and the syllabus.

### Announcements

• (M, 3-20) I have submitted final grades. I gave the overall median score of 76.6% a 3.1. Here is a plot of how the grades were distributed.

Thanks for the great quarter. I really enjoyed being your teacher and working through this material with you. Have a great break, and stop by to say hello sometime.

• (S, 3-18) Your final exam scores are on Catalyst. The median was 52/75 or 69%, and here is a histogram of the scores. I will post final grades next week.

• (M, 3-13) Our review session on Tuesday will be from 3:30-5:30 in Sieg Hall 225.

• (S, 3-11) Due to popular demand, solutions to MT1 are now posted on the calendar below. Note that the extra credit deadline has been extended to Tuesday.

• (F, 3-3) Extra credit opportunity: Problems 33-36 in Section 16.5 plus the following question, call it 33(b): "Explain how Green's First Identity is like integration by parts."
• This will be due Tuesday evening of finals week (3-13). We don't have class so I will ask you to turn it into my box in the math department mailroom, PDL C-138.
• Don't be intimidated by the problems. Once you sort through the notation (referencing Section 16.5) they are very doable. Ask me if you need help.
• You must work on your own. Since this will be test points, you should work on it like a test - except that you can use the book for help and ask me questions. Do not work with others or look for solutions online.
• You can earn up to two test points.

• (S, 2-18) For your practice, here is second the midterm from my summer quarter 324 class, and here are solutions. Recall other practice tests are on Andy Loveless' page.

• To those of you who haven't been doing as well as you would hope so far: my view is that it is never too late to turn things around. Do a lot of practice problems this week in preparation for the test (and not just Thursday night). Review your lecture notes, come to office hours, discuss the material with other students. If you put in the effort, you can improve!

• I will hold a review session Thursday from 4-5 in THO 119.

• (M, 2-13) There is a mini assignment (two problems) on 16.4 due Tuesday night (2-14). The point is to get you some hands-on practice with Green's Theorem before class on Wednesday.

• (T, 1-24) As announced in class last Friday, there is an extra credit opportunity: the "Volumes of Hyperspheres" project on p.1027 of the text. Due Friday, 2-3. (For part 4, doing n=5 is probably enough to see the pattern.)

• (M, 1-23) Midterm 1 is this Friday, covering 15.1-15.10.
• You may use one side of one page of hand-written notes (but no worked-out example problems). You may only use a scientific calculator.
• To practice: here are the first midterms from my 324 classes in the summer and in the fall. Solutions for the summer test; for the fall. Here are some other tests from Andy Loveless' page.
• I will hold an extra review session this Thursday from 5:15-6:15 pm in PDL C-36.

• (W, 1-18) The 15.9 HW (on spherical coordinates) will be due Monday the 23rd instead of this Friday.

• From time to time I will present graphics of 3-d regions, etc, to the class, and post these on the calendar. They are made in Mathematica, and to view them you need the free CDF player or Mathematica itself.

### Syllabus

• When and where: MWF 12:30-1:20 in THO 135
• Instructor: Tim Mesikepp
• Office: PDL C-34
• Office hours: M 2:30-3:30, W 3:45-4:45, F 8:30-9:20, or by appointment
• Email: mesiket (at) math.washington.edu
• Course content and text: See the math department's 324 syllabus.

• Homework: Homework is online through WebAssign. The first problem set (15.2-3) is due Friday, 1-6, and then homeworks are due every subsequent Wednesday and/or Friday (or Monday). You need to get access to WebAssign as soon as possible and login to see your assignments. If you purchased it for M124/5/6, you should still have access for this course.

• Exams: There will be two midterms and a final exam. There are no make-up exams. If you have a documented, verifiable and legitimate reason for missing a midterm, you must notify me in advance and I will give you your average on the other midterm and the final for that midterm. There is no such recourse for missing the final - you must take it. You may use a non-graphing calculator on exams.
• Exam dates:
• Midterm 1: Friday, January 27 - One side of one page of hand-written notes allowed (no worked-out problems or algorithms)
• Midterm 2: Friday, February 24 - One side of one page of hand-written notes allowed (no worked-out problems or algorithms)
• Final exam: Thursday, March 16, 8:30-10:20 - Two sides of one page of hand-written notes allowed (no worked-out problems or algorithms)

• Quizzes: We will have quizzes on most Fridays. If you have a documented, verifiable and legitimate reason for missing a quiz, I will give more weight to the rest of your quizzes. These will take place at the beginning of class. It is your responsibility to be on time.

• Quizzes: 3%
• Homework: 12%
• Midterm 1: 25%
• Midterm 2: 25%
• Final: 35%
I will set the grade scale for the course at the end of the quarter. The median will be in the 2.9-3.1 range. If you want a 4.0, shoot for a percentage in the mid 90's. If you want a 0.0, aim to get less than 50%. Last quarter the median was 69% and that earned a 3.1.

• Some things you are responsible for:
• Knowing the policies in this syllabus.
• Knowing when homework is due. This will always be visible on WebAssign and above on our course calendar.
• Announcements I make in class and post above in "Annoucements." So you should come to class and periodically check this site.

• Resources for help:
• You! Your drive, perseverance, and study. Your lecture notes, your creativity and your ideas. Most of your learning for this class will have to take place outside of class (!) as you reflect on and digest what we discuss in lecture.
• Do your best to pay attention in class. I would ask you to consider not using a laptop or phone during class, because these are districting to yourself and fellow students, especially in such a small room. Multitasking - like checking your email or Facebook while in class - is not helpful. It is rather remarkably detrimental. "When you try to multitask, in the short-term it doubles the amount of time it takes to do a task and it usually at least doubles the number of mistakes." - Dr. JoAnn Deak. (Similar summaries of research: NY Times, NPR - "The research is almost unanimous, which is very rare in social science, and it says that people who chronically multitask show an enormous range of deficits. They're basically terrible at all sorts of cognitive tasks, including multitasking.")
• The book.
• The homework.
