Enforced Prerequisites
: Math 254 or Math 254H with a C- or better, or instructor
permission.
Textbook:
I follow Lay's Linear Algebra Book (any edition will do).
There is a supplementary,free text, that some might find useful:
Linear Algebra, by K. Kuttler.
Learning Outcomes (from the Math Dept):
Upon successfully completing this course a student should,
1. Use Gaussian elimination to determine the solution set of a system of linear equations,
and describe the solution set.
2. Perform matrix operations, including finding the inverse or showing no inverse exists for
a square matrix.
3. Calculate determinants of square matrices and apply properties of determinants to
draw conclusions about solution sets of linear equations and invertibility.of matrices.
4. Find and use the matrix representation of a linear transformation associated to the
standard basis in Euclidean space R^n.
5. Use the definition to determine whether a subset of R^n is a subspace.
6. Determine if a collection of vectors is linearly independent or dependent, and find the
span of a set of vectors.
7. Use the rank-nullity theorem to draw conclusions about solution sets to linear systems
and the invertibility status of square matrices.
8. Determine a basis for and the dimension of a given subspace, including the null space
and column space of a matrix and the eigenspaces of square matrices.
You are expected to do all of the homework. One problem from each assignment is chosen for grading.
Exams:
Midterm, Scheduled for Oct 16. 80/200 points will come from homework problem(s) and
from the class notes. No electronics allowed (needed).
Voluntary Extra Credit problems, due December 5, at time of final exam.
Final exam, scheduled for December 5, at 9:30am in our classroom. It is in 2 parts. It covers material of the second portion of the class. The take-home portion is found HERE .
You must hand in the take-home portion at the time of the in-class exam:
Be sure to bring the take-home portion to the in-class portion of the
final exam. No electronics allowed (needed) for the in-class portion of
the exam.
There is no make-up
midterm unless it is due to a documented emergency.
If you miss the midterm due to
the emergency, you will have the final exam count for the combined weight of the final and the midterm.
There are no make-up finals.
If you miss the final you will have to petition for an incomplete fail.

How to succeed in this course:
The class moves fast and you will find
it difficult to catch up if you fall behind.
If you miss a day of class you should obtain notes from
one of your classmates and study the missed lesson as soon as possible.
Remember, class material shows up in the exams.
This course requires a lot of time. Plan accordingly: for every hour of
class time, plan on 2-3 hours of study time.
Many of the students who perform best, not surprisingly, are those that seek help during office hours from the instructor.
Make time for office hours. It's one of the best and fastest ways to clarify questions and perform better in exams
Be sure to seek help
immediately if you are having trouble with any concepts
by asking questions in class.
Study in small groups.
The exams are structured to reward hard work and/or for
being clever. I expect clear and structured ideas.
If you come prepared for the exam, you should be able to do well. The questions come from a subset of all of the concepts learned, so start by making a list of things you think you should know and
work through it in your studies (you can even come by during office hours to
get an opinion regarding the completeness of your list). Don't squander the following opportunity: roughly
50% of your grade in the exams is based on class material and problems
from the homework. The rest is based upon the material assigned.
That means that you will be hard pressed to claim that you were caught by
surprise or that you were well prepared for the midterm
if your exam grade is low.
