There will be between 8 and 10 assignments. They are due at the beginning of class. Click here for a list of exercises. The lowest (or missing) assignment grade will be dropped when computing the course grade.

### What is expected of the student:

Math 2121 is the second half of a mathematically intensive second year of linear algebra, with the syllabus given above. You will continue to learn to read and write mathematical proofs. This is perhaps the most important intellectual feature of modern mathematics, and correspondingly an essential step in moving on to more advanced topics in later courses. Assignments will be an important part of the course, so that you will have the feedback you need to develop new skills. Accordingly, Math 2121 is a demanding course, and you should be prepared for a time commitment of at least six hours per week. The assignments are to be thought of as take-home exams and should be done entirely on your own. All those involved in copying will receive a negative grade on the assignment in question. In addition, all academic offenses will be reported to the Dean's office, and may result in further penalties. Regarding Scholastic Offences and Penalties, see pp. 23-26 of the Academic Calendar or refer to Scholastic Discipline for Undergraduates. Homework will be posted regularly on my webpage (see above) and collected in class.

### Important Senate Policy

Students are responsible for ensuring that their selection of courses is appropriate and accurately recorded and that all course prerequisites have been successfully completed. If the student does not have the prerequisites for a course, and does not have written special permission from his or her Dean to enroll in the course, the student may be removed from the course and it will be deleted from the student's record. This decision may not be appealed. A student will receive no adjustment to his or her fees in the event that he or she is dropped from a course for failing to have the necessary prerequisites.

Scholastic offences are taken seriously and students are directed to read the appropriate policy, specifically, the definition of what constitutes a Scholastic Offence, at this web site.

### Midterm Information

The midterm will be held on Tuesday, March 19, 2013, 5-8pm

Here is a Review for the Midterm.

### Final Exam Information

The final exam will be on Monday, April 15, 2-5pm

Here is a Review for the Final Exam.

Please read the section below if you have a conflict with either exam.

### Make-up exams and conflicts

If you know ahead of time that you are unable to attend a midterm or final exam, you must let your instructor know at least two weeks in advance so alternative arrangements can be made. See also the University's policy on final exam conflicts.

If you have a conflict with another final exam, you must contact Rob Downes in the Registrar's Office by mid March to arrange a special time/place to write the final. If you have a conflict with a midterm for a year-long course, you must contact the instructor of the other course. If you have three final exams in 3 consecutive periods, you must contact the Dean of your faculty. In all cases, please let your instructor know.

### Medical Excuse Regulations

If you are unable to meet a course requirement due to illness or other serious circumstances, you must provide valid medical or other supporting documentation to the Dean's Office as soon as possible and contact your instructor immediately. It is the student's responsibility to make alternative arrangements with his or her instructor once the accommodation has been approved and the instructor has been informed. In the event of a missed final exam, a "Recommendation of Special Examination" form must be obtained from the Dean's Office immediately. For further information please see: University policy on medical excuses.

A student requiring academic accommodation due to illness, should use the Student Medical Certificate when visiting an off-campus medical facility or request a Record's Release Form (located in the Dean's Office) for visits to Student Health Services. The form can be found at this web site.

Failure to follow these rules will result in a grade of zero.

### Accessibility Statement

Please contact the course instructor if you require material in an alternate format or if you require any other arrangements to make this course more accessible to you. You may also wish to contact Services for Students with Disabilities (SSD) at 661-2111 x 82147 for any specific questions regarding an accommodation.
