Math 152, Section 205, Spring 2012
This page concerns Math 152, Section 205, for Winter 2011-12 term II (i.e., Spring 2012).
| Our Section | This is the website for Section 205 of Math 152, Spring 2012. The material here is different from the material in other sections for this term. We will often refer you to the pages in the Section 206 website, which has a lot of material that is somewhat shared by the courses. All homework, grading schemes, exam dates/locations, etc. for Section 205 are set on this website, not on any other instructor's website. In this section we will cover PageRank and not cover electrical (resistor) networks. The following course outline gives information on the topics to be covered and various course policies (e.g., grading). |
|---|---|
| Overview and Materials | We shall follow the notes of Froese and Wetton, which are coordinated with the labs. The textbook "Linear Algebra and Its Applications" by David C. Lay is recommended but not required. You may also be interested in notes of Feldman on various topics to be covered. A blog (last revised January 30, 2012) will be used to supplement the Froese-Wetton notes, especially when we give material not covered there, such as PageRank. The blog is an outline, not a complete text. Other materials may be added to the course. |
| Final Exam | The final exam will be held on Monday, April 16, 3:30, in OSBO A. You will be given this formula sheet with the exam. In the last two days of class, we will review problems of past exams, available here; we will focus on recent exams, such as April 2008--2011, whose course content is essentially the same as ours. We will start with April 2008, and work our way up; we will not cover the April 2011 exam, since the exam, with hints, solutions, and explainations to each problem is available here, courtesy of the Math Exam Resource Wiki. Group office hours /review before the exam: Thursday, April 12, 10-11am, Friday, April 13, 9:30-11am; both will be held in MATH 105. The Math Learning Centre is open 9am-9pm, weekdays, April 10-24. |
| Second Midterm | Here is the second midterm with solutions. The second midterm will be on March 16. Exam conditions will be the same as last time: 40 minute exam, 12:10-12:50pm (i.e., during the usual class time), A-K in Woodward 4, L-Z in Woodward 6. The midterm will cover material covered in class up to March 9, including 4.1-4.5 (matrices, random walks, transpose and inverse), 4.7 (determinants), 4.8.2 and 4.8.3 (least squares); also 6.1 and 6.2, but only for 2 x 2 matrices with real eigenvalues. Here are some practice problems for the midterm; this includes a list of formulas and information that you will be given; here are solutions. Office hours before the exam: Wednesday, March 14, 3-4pm, location will probably be HEBB 12 (awaiting confirmation); Thursday, March 15, 10-11am, location will probably be HEBB 10 (awaiting confirmation). |
| First Midterm |
Solutions to the first midterm are available.
The first midterm will be on February 10; students with last name starting
with A-K will be in Woodward 4; those starting with L-Z will be in Woodward 6;
the exam is 40 minutes and will start at 12:10pm. Please wait outside
the exam room until you are called in. Please bring student ID; you will
need it if your photo does not appear on the Faculty Service Centre database.
You will be seated in alphabetical order (last name).
Office hours before the midterm: Wednesday, 3-4pm, Math Annex, room 1118;
Thursday, 11:15-12:15pm, Math Building, room 203.
The first midterm will cover class up to Friday, February 3; this means sections 2.1-2.6, 3.1-3.3, plus the applications of curve fitting and PageRank (see the blog for material). Here are some practice problems for the midterm; this includes a list of formulas and information that you will be given. Brief solutions are available. |
| Labs | Six lab assignments will be common to all sections. See this webpage for details. The labs will teach you MATLAB. The linear algebra concepts in the labs will be part of the exams; MATLAB itself, e.g., syntax and programming, will not be on the exams. |
| Homework |
Late homework will not be accepted; solutions may be released soon
after the homework is handed in.
Again,
the homework assignments in this section (205) may differ somewhat
from homework in other sections.
Homework #1: Problems 2--4 of this assignment and this problem on PageRank are due on January 13. Solutions are, respectively here and here. Homework #2: Problems 2--5 of this assignment and this problem on the topics we've covered are due on January 20. Solutions are, respectively here and here. Homework #3: Problems 2--6 of this assignment, due January 27; note that for the hint in 6(b), we did not mention the word "normal" in class, but we used this idea; for example, the direction normal (or orthogonal) to 6x+2y+3z=4 is any vector proportional to [6 2 3]. You are also free to ignore the hint... Solutions are here. Homework #4: Problems 3, 6-8 of this assignment, and this additional problem due February 3. You should also be able to do problems 2, 4, and 5 of this assignment, but don't hand these in. Solutions are, respectively here and here. Homework for February 10: study the sample midterm questions above and review all the homework questions. Nothing to hand in for February 10 (which is the day of the first midterm). Homework #6: Problems 1-3 and 5 of this assignment, due February 17. Solutions are here. Homework #7: Problems 2-7 of this assignment, due March 2. Solutions are here. Homework #8: Problems 2-5 of this assignment, and this additional problem, due March 9. Solutions are, respectively here and here. Homework #9: Problems 5,6,7,9 of this assignment, and this additional problem: (a) show that the product of two orthogonal matrices is orthogonal (see Problem 5 or the notes or wikipedia for the definition of orthogonal matrix); (b) what type of transformation is the product of two reflections in the plane? Justify your answer. Due March 23. Solutions are, respectively here and here. Homework #10: All of this assignment. Due March 30. Homework #11: All of this assignment. This will not be collected. |
| Midterms | There will be two 40 minute midterms, held 12:10-12:50pm, on February 10 and March 16. They will be held in Woodward 4 and Woodward 6; you will be assigned a room and a seat closer to exam time; if you have any special seating needs, please e-mail me by January 31 (jf@math.ubc.ca). See the course outline for more details. |
