Linear Algebra (110.201) syllabus, spring 2007



Final Exam:

You can come see your exam and grade on Monday from 2 to 5pm in my office (Krieger 222).

The Final Exam will take place on Thursday 5/3 from 9 am to 12 noon in Shaffer 3. Those of you who have a conflict with another Math exam (Diff Eq. or Calc III) will take the other exam at the regular time, and the exam for this class on Friday 5/4, from 9 am to 12 noon in Bloomberg 176.
Material for the Final: everything we have covered, with a little more weight on what we've seen since the second Midterm. More precisely, this corresponds to the following sections of the book:
all of chapters 1, 2, 3, 4, sections 5.1 (except "correlation"), 5.2, 5.3, 6.1, 6.2 (except "determinants and permutations"), Cramer's rule in 6.3, 7.1 (except "dynamical systems and eigenvectors"), 7.2, 7.3, 7.4, 8.1 and 8.2.
For those of you who haven't studied differential equations/systems, sections 7.5-7.6 and chapter 9 are very useful for applications. You will not be tested on that material in this class, but you should eventually learn it.

Lectures:  Monday, Tuesday, Wednesday at 10 in Shaffer 3, Professor Paupert.

Textbook:  Linear Algebra with Applications (3d ed) by Otto Bretscher.

Material:  The material we will cover in this course roughly corresponds to chapters 1-8 of the textbook.

Section:  The class is broken into smaller groups for problem sessions, conducted by a teaching assistant (TA), who is a graduate student in the Department of Mathematics. The TA is there to answer your questions about the material of the preceding and current homework assignments and the material covered in class. The TA will not do the homework for you.

Homework:  Assignments will be given on-line each week, usually by Tuesday. The homework problems need to be done in order to develop command of the material; this will prepare you for the quizzes and exams. In writing up any problem, you must show all the steps leading to your solution. A few problems are to be submitted at the beginning of the lecture the following Tuesday. Selected problems will be graded by your TA and returned in Section the following Thursday or Friday. No late homework will be accepted.

Quizzes:  There will be quizzes in Section every other week, beginning February 1-2, except after exams. The quizzes should be easy and are only here to encourage you to review the material regularly. You may not use books, notes, or calculators during quizzes. There will be no making up of missed quizzes.

Exams:  There will be two Midterms and a Final.You may not use books, notes, or calculators during exams. Following the department's policy, there will be no making up of missed exams. If you miss a Midterm exam for a valid reason, the grade for that exam will be replaced by a neutral grade (a weighted average of the other exam grades).
Students with documented disabilities or other special needs that require special accomodation must register with the Office of Academic Advising. After that, contact the instructor at least a week before each exam; we will need to have received confirmation from the Office of Academic Advising.
The Midterms will take place during the lecture period on Tuesday, February 20 and Tuesday, April 3 in Shaffer 3. The Final will take place from 9am to 12noon on Thursday, May 3 (according to the Registrar's webpage; to be confirmed).

Grading:  Homework: 10%. Quizzes: 10%. Midterms: 20% each. Final: 40%. The two lowest homework grades will be dropped, as well as the lowest quiz grade.

Office hours:  Tuesday from 3pm to 5pm in my office, Krieger 222. If you can't make it, write me an email at paupert@math.jhu.edu, or call 410-516-5132 to schedule an appointment.
In addition, there are pooled TA office hours in the Math help room, Krieger 213, in which the Math department TAs are on duty in shifts. The hours are Monday-Thursday 9am-9pm and Friday 9am-5pm.

A word from the Ethics Board:  The following text is quoted from the Academic Ethics for Undergraduates guide:
"Cheating is wrong. Cheating hurts our community by undermining academic integrity, creating mistrust, and fostering unfair competition. The university will punish cheaters with failure on an assignment, failure in a course, permanent transcript notation, suspension, and/or expulsion. Offenses may be reported to medical, law, or other professional or graduate schools when a cheater applies. Violations can include cheating on exams, plagiarism, reuse of assignments without permission, improper use of the Internet and electronic devices unauthorized collaboration, alteration of graded assignments, forgery and falsification, lying, facilitating academic dishonesty, and unfair competition. Ignorance of these rules is not an excuse.(...) On every exam, you will sign the following pledge: I agree to complete this exam without unauthorized assistance form any person, material or device.
