 Assignment #3 posted on connect, due Monday,
January 30 at midnight.
 Assignment #2 posted on connect, due Monday,
January 23 at midnight.
 A course outline
is available.
 Online notes for the class are found below.
 Overview:
 The course concerns linear algebra concepts, stressing their
application and their connection to geometry. A detailed week by
week outline of the material can be found below.
 Online notes for the class are found below.
These notes will be used for the course instead of a commercial textbook.
 Other resources to help you with the course material are available,
listed below.
 Webwork Assignments are posted online every
week on Fridays and have a deadline for submission of Monday (after 10 days)
at midnight.
 Students are responsible for completing six one hour
computer labs using the software, MATLAB.
 Grade breakdown for the course:
 homework (WebWork) 10%
 computer labs 10%
 2 midterm tests worth 15% each
 final exam 50%
 There will be a common final exam. Midterm
marks may be scaled to each section's average on the final exam (this
scaling may be done in blocks of sections). More details on
test and exams can be found below.
 Test #1 is set for Wednesday February 8/Thursday February 9 (in class).
 Test #2 is set for Thursday March 16/Friday March 17 (in class).

We will be covering
all six chapters, excluding the material listed as "additional topics".
 Additions and Corrections:
 Corrections:
 There is a typo on page 24, example 2.7, the last line.
It should read proj_b a instead of proj_a b.
 Additional notes from Professor Yue Xian Li are available on:
 Additional notes written by Joel Feldman on the
subject of complex numbers are available
here.

 Webwork Assignments:
 Webwork Assignments are posted online every
week on Fridays and have a deadline for submission of Monday (after 10 days)
at midnight.
 There will be eleven assignments. Your lowest mark will be dropped
from the average.
 WeBWorK assignments are posted on the
UBC connect system.

Computer Labs:
 Computer labs using the mathematical software package MATLAB begin
in the second week of classes. Each student does a lab every two weeks,
starting in the second or third week. Look at your lab section
registration information to see where your lab will be held and what week you
start.
 MATLAB material will be tested on midterms and exams.
 The lab assignments are posted on the
UBC connect system. Submissions are also done in this system in .doc
format.
 The first lab is due Friday, January 20 at midnight.
Later labs are due at midnight on the day of your scheduled lab.
 UBC has a site license for MATLAB.
Registered students can download it on their own computers.
Detailed instructions can be found here
here.
 The lab rooms are available for your use outside of your
lab hour. A schedule for the labs is posted
here. Whenever there is nothing listed here, the room is
free for your use.
