Course Information and Syllabus


Recitations

Recitations meet on Tuesdays starting from Sep 9. No recitation on Nov 11. You must enroll in a specific section. Your homework and exams will go to that section. Default recitation sections are assigned by the Registrar. You may change your recitation on Membership module and view your grades on Gradebook.

Note about evening office hours: the students do have access into the building with their ID cards. But doors to 3rd and 4th floors of E18 are locked after 6pm. Please contact the recitation instructor if you plan to come to office hours, so that they can let you in.


Homework and Collaboration

Homework will be posted weekly in the Problem Sets section of the class website. Assignments will be due on Thursday, BEFORE 4PM. Please put them in the box for your section in E17-131. Please staple them (you may use the math stapler). They are due every week except exam weeks and are returned in recitation.

Late homework will not be accepted and no extensions are granted. However, your lowest homework grade will be dropped.

The homeworks are essential in learning linear algebra. They are not a test and you are encouraged to talk to other students about difficult problems---after you have found them difficult. Talking about linear algebra is healthy. But you must write your own solutions.


Exams

Many students find the second exam more challenging than the first exam. It is not surprising to see a much lower mean on the second exam as this part of the course trains students to go past the mechanical and computational, emphasizing the conceptual and the ability to tackle new problems.

The use of calculators or notes is not permitted during the exams. Taking another course at the same time is not an excuse for missing the in-class hour exam. There will be no make-up exams in this course.


Concerns about homework, grading, exams: see your recitation instructor.

Checking grade records: online at Gradebook.

Changing recitation: online at Membership module.
