This course provides an introduction to linear algebra, being the first semester of a year-long sequence. We will cover most of chapters 1-4 of the text, and selections from later chapters, with additional material as time allows.

Homework sets will be announced on this page each week. The homework will not be collected. However, questions related each problem set will appear in weekly quizzes, usually given each Tuesday (see below for weekly details). Additional take-home quizzes may be occasionally assigned. The homework will account for the most substantial part of your learning, so you should take the homework very seriously. If you do the homework you will also find the quizzes and exams much easier.

Quizzes are "open book, open notes.''

Exams are not open book (see below).

Calculators, computers, phones, or other electronic devices are not permitted on quizzes or exams.

Attendance policy:
Attendance will not be taken, but you are of course responsible for everything said in class. There will be no make-ups for missed quizzes. Instead I will drop the lowest quiz score for each student.

You are expected to take exams on the scheduled dates. Make-ups for exams require official documentation (doctor's note, letter from coach regarding away games, letter from the Dean of Students, etc.). If we have a snow day on a scheduled exam date, the exam will be on the following class date. The final exam will be scheduled between May 2 and May 9. You are expected to leave these dates open until we get a definite date/time for the final exam. Do not schedule travel before May 10. If you already have travel scheduled and do not want to cancel it, you probably should drop this course.

Academic Integrity: Academic dishonesty is prohibited in all programs of the University, and sanctions may be imposed on any student who commits an act of academic dishonesty. Details on UML policy can be found here.

Examinations: There will be three exams and a final exam. Exams are closed book. However, you are allowed to bring one double-sided 8.5" x 11" sheet of notes.

Homework assignments will be announced weekly on this page. Check periodically for updates.
