General Information


Linear Algebra, Fifth edition, by Friedberg, Insel, Spence

Scheduled Lectures

MWF 11:30—12:35
(x-hour) Tuesday 12:15—1:05
Location: Zoom meeting
Our current plan is to meet on Zoom for lectures on Monday, Wednesday, Friday from 11:30-12:35 (Eastern Time). The video recordings will then be shared on Canvas for those who cannot attend the scheduled lectures. The instructor will try to dedicate seperate meeting time on zoom for those who cannot attend the live lectures. If live lectures turn out to be difficult due to technological issues, we will have pre-recorded lectures instead.

Office Hours:


There will be one midterm exam and one cumulative final exam. The exams are open-book. Students are allowed to have at least 24 hours to finish the exams and submit answers on Canvas, counted immediately after the posting of the problems. Students may only refer to their notes or the textbook to complete their exams. In particular, students are not allowed to receive any help from peers or online resources that are not provided in class. To receive credits, students should always provide a proof for any statement that is not covered in the past lectures.

The oral exams will be conducted on Zoom. The duration is about 20 mins for each student. Students are responsible for making an appointment with the instructor during the term.

If you have a conflict with one of the midterm exams because of a religious observance, scheduled extracurricular activity such as a game or performance [not practice], scheduled laboratory for another course, or similar commitment, please contact your instructor as soon as possible. If you must miss a class, it is your responsibility to submit all homework on time, and to arrange to get notes from a classmate.

The Honor Principle

Academic integrity is at the core of our mission as mathematicians and educators, and we take it very seriously. We also believe in working and learning together.

Cooperation on homework is permitted and encouraged, but if you work together, try not take any paper away with you. In other words, you can share your thoughts, but try to walk away with only your understanding. In particular, you must write the solution up individually, in your own words. This applies to working with tutors as well: students are welcome to take notes when working with tutors on general principles and techniques and on other example problems, but must work on the assigned homework problems on their own. Please acknowledge any collaborators at the beginning of each assignment.

On exams, you may not give or receive help from anyone. Plagiarism, collusion, or other violations of the Academic Honor Principle will be referred to the Committee on Standards.

Special Considerations


Students with disabilities who may need disability-related academic adjustments and services for this course are encouraged to see the instructor privately as early in the term as possible. Students requiring disability-related academic adjustments and services must consult the Student Accessibility Services office (Carson Hall, Suite 125, 646-9900). Once SAS has authorized services, students must show the originally signed SAS Services and Consent Form and/or a letter on SAS letterhead to their professor. As a first step, if students have questions about whether they qualify to receive academic adjustments and services, they should contact the SAS office. All inquiries and discussions will remain confidential.

Mental Health

The academic environment at Dartmouth is challenging, our terms are intensive, and classes are not the only demanding part of your life. There are a number of resources available to you on campus to support your wellness, including your undergraduate dean , Counseling and Human Development , and Student Wellness Center .
