Text: Contemporary Linear Algebra by H. Anton and R.C. Busby

Purpose: Linear algebra together with Calculus provide the basic mathematical knowledge needed for other more advanced courses (in Mathematics, Statistics, Physics, etc.) and for work in a wide variety of fields, including telecommunications and web engineering.

Material to be covered:
Chapter 1 - Sections 1.1 to 1.3.
Chapter 2 - Sections 2.1 to 2.3.
Chapter 3 - Sections 3.1 to 3.5.
Chapter 4 - Sections 4.1 to 4.4.
Chapter 5 - omitted
Chapter 6 - Sections 6.1 to 6.4.
Chapter 7 - Sections 7.1. (Possibly to 7.5)
Please see the class schedule for more details.

There are 5 weekly assignments.  Assignments are due Wednesdays at 7 PM, and are to be deposited in the appropriate mailbox on the third floor of CAB.  Late assignments cannot be accepted under any circumstances.  All assignment marks will be considered in the calculation of your homework mark.  Please write legibly, use letter-sized paper with a cover sheet, and staple all pages together.
Please see the assignment schedule for more details.


Final grades will be adjusted to roughly fit a bell curve.

Important  Dates:

Midterm -- In class. Thursday, May 24.                  
Final Exam – Thursday June 14, 7:00 pm. 3 hours.
Last day for withdrawal from the course with grade W  Friday, June 1.
Deferred Final Exam
TBA, it should be written within two weeks of final exam.

Note: There is no deferred Midterm Exam. If you have a legitimate excuse (e.g. illness), then weights for the Midterm will be transferred to the Final.

What to bring to the exams:
- Student ID ("One" Card).
- Pen/pencil, eraser.
Calculators or formula sheets are not permitted. (You will have no need for the typical functions of a calculator during exams, as all the computations will be simple enough that you can do them in your head. On the other hand, an extremely sophisticated calculator could give some students an unfair advantage.)

NOTE 1: Students who require accommodations in this course due to a disability affecting mobility, vision, hearing, or mental or physical health are advised
 to discuss their needs with Specialized Support and Disability Services, 2-800, SUB, (phone) 492-3381 or (TTY) 492-7269.

NOTE 2: Policy about course outlines can be found in Section 23.4(2) of the University Calendar.

NOTE 3: The University of Alberta is committed to the highest standards of academic integrity and honesty. Students are expected to be familiar with these standards regarding academic honesty and to uphold the policies of the University in this respect. Students are particularly urged to familiarize themselves with the provisions of the Code of Student Behavior (See Calendar Section 23.4(2)c and online at , see also ) and avoid any behaviour which could potentially result in suspicions of cheating, plagiarism, misrepresentation of facts and/or participation in an offense. Academic dishonesty is a serious offense and can result in suspension or expulsion from the University.

Course Description: Systems of linear equations. Vectors in n-space, vector equations of lines and planes. Matrix algebra, inverses and invertibility. Introduction to linear transformations. Subspaces of n-space. Determinants. Introduction to eigenvalues and eigenvectors. The dot product and orthogonality. Applications. Math 125 is an enriched version of MATH 120. It covers the same basic topics as MATH 120, but in greater depth and additional applications. MATH 125 is recommended for students who plan to take further courses in algebra. Math 120 cannot be taken for credit if credit has already been obtained in MATH 102, 125 or 127.
