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 E17131.
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 problemsafter you have found them difficult. Talking about linear algebra is healthy. But you must write your own solutions.
Concerns about homework, grading, exams: see your recitation instructor.
Checking grade records: online at Gradebook.
Changing recitation: online at Membership module.
