("The Growing Importance of Linear Algebra in Undergraduate Mathematics", Alan Tucker,

about the history of linear algebra; the bottom of page 5 and top of page 6
(the third and fourth pages of the article) briefly describe
the origin of matrix multiplication.

Please feel free to come by my office any time during scheduled
office hours.
You are welcome to
visit at other times, but in that case you might want to make
an appointment, just to make sure that I will be there then. You can
make an appointment simply by talking to me before or after class, by
calling me at
my office
or at home, or by sending
email.
You may also ask any questions directly via phone or email. If I'm
not in when you call, please leave a message on the voicemail or
answering machine with your name, number, and a good time for me to
call you back. I will try to respond to your phone or email message
as soon as possible.
Prerequisites:
MATH 3325, or an equivalent course where you learn the basics of writing proofs.
COURSE OBJECTIVES:
Upon successful completion of the course,
you will be able to prove (and occasionally discover) theorems in
linear algebra, at the level of abstraction of linear transformations
and vector spaces; other major topics include eigenvalues/eigenvectors and inner product spaces. You will know, understand, and be able to apply,
prove, and explain major results in this area. You will be better
able to independently read advanced mathematics.
Note:
In contrast to Matrix Algebra (Math 3323), we will be
focusing on proofs and theory instead of applications (though theory
lies closer to applications in linear algebra than it does in, say,
analysis), vector spaces instead of R^n, and linear transformations
instead of matrices. Otherwise, many topics will look familiar.
Textbook:
Linear Algebra Done Right, 3rd ed., Sheldon
Axler, Chs. 16, 8.
We will generally spend one to two class periods per
section (see Table of Contents), though parts of Chs. 1, 2, and 4
should be review, and we will go a little faster through these.
We will skip some sections, as announced in class.
You will spend a substantial amount of time outside of class reading
the textbook. The course will be structured to encourage and support
you in this endeavor. Inclass activities will center around our
making use of what you have read outside of class.
GRADES:
Homework and Participation:
For each section of material we encounter, there will be three kinds of homework, as follows (more details are on a separate handout):
 Advance preparation (20%):

You will read the section
carefully, write responses to reading questions, create some of your
own questions, and reflect. The written part of this assignment will
be due before we discuss the material in class.
 Warmup exercises (10%):

On the day of our class
discussion over the material, we will discuss easier warmup exercises.
You will prepare your answers, in writing, before class, and the class
will share answers in small groups or whole class discussions.
I expect everyone to attend and participate actively in class, in
particular to speak up during class discussion with questions and
ideas, and to work well with others. Your active participation in
class will constitute a substantial part of this part of your grade
for the course.
 Main exercises (30%):

After our class discussion over
the material, you will turn in clearlywritten solutions to harder
homework problems. These will generally be due weekly.
Graduate students taking this class will be assigned additional
main exercises, in accordance with university policy.
Written assignments (for all three kinds of homework) will not be
accepted after they are due, except in extenuating circumstances that
you explain to me as soon as possible. Incomplete homeworks will be
accepted, though, so please turn in whatever work you have completed
when homework is due. You are encouraged to work together on your
homework, but you must write up your solutions by yourself.
Exams:
 Midterm (15%):

The midterm will cover all material we have discussed to that point,
and will be on
Wed., 18 Mar.
 Final (25%)
 The final exam will be comprehensive over all material we discuss in class. The final will be on
Fri., 15 May, 10:00 a.m.12:45 p.m.
Makeup tests can be given only in extraordinary and unavoidable
circumstances, and with advance notice.
POLICIES:
Academic dishonesty:
It is UTEP's policy, and mine, for all suspected cases or acts of alleged scholastic dishonesty to be referred to the Office of Student Conduct and Conflict Resolution for investigation and
appropriate disposition. See Section II.1.2.2 of the Handbook of Operating Procedures.
Attendance:
Due to the course structure, attendance is mandatory. There is no particular penalty for missing a particular class, but you cannot get a good participation grade if you miss too many classes. I will usually "excuse" an absence if you tell me about it in advance, or, in cases of emergencies, as soon as possible afterwards. My goal is for class meetings and activities to complement, rather than echo, the textbook, and thus for every class to be worth attending.
Drop date:
The deadline for studentinitiated drops with a W is Monday, April 6. After this date, you will not be able to drop the class (as per the Dean's office). Furthermore, a grade of incomplete is only for extraordinary circumstances, such as a missed exam.
I hope everyone will complete the course successfully, but if you are having doubts about your progress, I will be happy to discuss your standing in the course to help you decide whether or not to drop. You are only allowed three enrollments in this course, and students enrolled after Fall 2007 are only allowed six withdrawals in their entire academic career, so please exercise the drop option judiciously.
Courtesy:
We all have to show courtesy to each other, and the class as a whole, during class time. Please arrive to class on time (or let me know when you have to be late, and why); do not engage in side conversations when one person (me, or another student) is talking to the whole class; turn off your cell phone (or, for emergencies, at least set it to not ring out loud), and do not engage in phone, email, or text conversations during class.
Disabilities:
If you have, or suspect you have, a disability and need an accommodation, you should contact the Center for Accommodations and Support Services (CASS) at 7475148, cass@utep.edu, or Union East room 106. You are responsible for presenting to me any CASS accommodation letters and instructions.
Exceptional circumstances:
If you anticipate the possibility of missing large portions of class time, due to exceptional circumstances such as military service and/or training, or childbirth, please let me know as soon as possible.
