Required Materials:
You are required to bring the following to every class.
  • Text: Linear Algebra: A Modern Introduction, 2nd Edition, by David Poole.
  • Graphing Calculator: TI-81, TI-83, TI-85, TI-86, etc. No calculator swapping is permitted during exams, and calculators may not be allowed for some exams.
Grades:
  • There are 600 total possible points.
  • Homework and quizzes are worth 100 points.
  • There will be three in-class exams, each worth 100 points.
  • The final exam is worth 200 points.
  • Grades will be awarded as follows:
    • 90-100% = A
    • 80-89% = B
    • 70-79% = C
    • 60-69% = D
    • 0-59% = E
  • An I (Incomplete) will be awarded only if all the following conditions are met:
    • The student has completed all but a small portion of the required work
    • The student has scored at least 50% on the work completed
    • The student has a valid reason for not completing the course on time.
    • The student asks for an incomplete before grades are due (48 hours after the final).
    • The student agrees to make up the material in a short period of time.
Exams:
  • In order to make up a missed exam, you must produce written evidence within 48 hours of the exam which shows that you had a legitimate reason to miss the exam. A legitimate reason is something fairly catastrophic, such as a serious illness. Neither a head cold nor a plane ticket counts as a legitimate reason for missing an exam.
Homework:
  • There will be a homework assignment for each section from the book which is covered in class. There may be additional handouts.
  • A subset of the assigned homework problems will be graded.  However, all of the problems are important.
  • Homework for a given section is due at 8:05 AM on the date listed in the table below. Late homework will not be accepted.
  • You are encouraged to discuss homework problems with me, with tutors, and especially with each other. However, you may not copy solutions from other students.
  • Your work will be graded on clarity as well as correctness.  It is your responsibility to make your homework clear and complete. Each solution must be understandable to another student in the class who has read the problem but not solved it.   Homework that is messy, illegible, or that lacks clear explanations will not be graded.
  • Here is a sample homework solution.  Your solutions should exhibit (at least) the level of detail and completeness in the sample.  (You do not need to type your solutions, and you do not need to state each problem.)
Quizzes:
  • There may be occasional quizzes, depending on the performance of the class.
  • Quizzes will count toward your homework grade.
  • There are no makeups for missed quizzes.

Homework Problems:

The problems and due dates listed here are tentative. There may be changes during the course of the semester.

If you determine that formal, disability-related accommodations are necessary, it is very important that you be registered with the Disability Resource Center (621-3268; drc.arizona.edu) You should notify me of your eligibility for reasonable accommodations by Friday, September 1st. You and I can then plan how best to coordinate your accommodations.

Students found in violation of the Code are subject to penalties ranging from loss of credit for work involved to a grade of E in the course, and possibly risk suspension or probation. The Code of Academic Integrity will be enforced in all areas of the course, including, but not limited to, tests and quizzes. For more information about the Code of Academic Integrity policies and procedures, including information about your rights and responsibilities as a student, see http://dos.web.arizona.edu/uapolicies/.
