This course has two goals: (1) to introduce to abstract mathematics, in this course you will learn about the "art of mathematical proof". Your assignments and exams will be evaluated on your ability to write proofs as well as in your knowledge of linear algebra; (2) To introduce you to Linear algebra. What is linear algebra?

Linear algebra is the study of vector spaces and linear transfomations. A vector space is a structure that abstracts and generalizes familiar objects from geometry and algebra. A linear transformation is a function between two vector spaces that preserves the structure.

Linear algebra is one of the most powerful mathematical tools used widely throught science and mathematics. This is one of my favorite subjects and I hope that you will like it too! I hope the following quote will inspire you to participate in this course.

"Mathematics is not for spectators; in order to gain in understanding, confidence, and enthusiasm one has to participate." M.A. Armstrong



Of course, I invite you to visit the mathematics library (located in the second floor of Bradley Hall) and become acquainted with as many linear algebra books as you wish.

I encourage you to come to my office to discuss homework problems (yes, you can come before the homework is due), things that you don't understand in the course, opportunities for an REU (Research Experience for undergraduates) or if you are wondering what course to take next and need a little guidance.


There will be two (probably part in-class and part take-home) exams and a final examination. They will probably be held during the weeks of Oct. 21 and November 18. The exact dates will be announced during class at least one week before the exam.

The Registrar has schedule our final exam for Saturday December 7 at 1:30 pm. Please, do not make plans to leave Hanover before the exam.


There is a project for this class. Click here to find out more about it.

Homework Policy and Guidelines

If you do not follow this guidelines, your homework will be returned to you ungraded.


The course grade will be based upon the scores on the homework, two exams, participation (this means attending class and office hours as well as asking and responding to questions), the project and the final exam.

Exams (2) 20% (each)
Homework 10%
Project 15%
Participation 5%
Final Exam 30%

The Honor Principle

On Exams: No help given or received from anyone. You may not use books or notes during in-class exams. For take-home exams you can use your class notes only.

On Homework: Collaboration is permitted and encouraged, but NO COPYING . In other words, you should feel free to talk to other students while you are in the process of thinking about a problem. However, when it comes time to write up your solutions, you should do this by yourself without outside assistance.


Students with disabilities who will be taking this course and may need disability-related classroom accommodations are encouraged to make an appointment to see their instructor as soon as possible, certainly within the first two weeks of the course. Also, they should stop by the Academic Skills Center in Collis Center to register for support services.
