16 Weeks of Linear Algebra...
... you won't believe what happens in week #6!
I have given in to the Dark Side, and this course will have some Blackboard components. Mainly we will use:
The main class website resides at
We will be using the iClicker platform for quick
in-class interactions (mini-quizzes). Reference:
Clicker @ SDSU (Instructional Technology
The Homework Server (WeBWork) is not yet up Target: Up by Friday [Second Week of Class].

Supplemental Instruction (SI) Hours
Study sessions are offered for this course and multiple SI sessions will be offered each week. Supplemental Instruction is an academic assistance program which provides peer-led group study sessions to assist students in traditionally difficult courses. Check out the [SI Calendar]
SI sessions are facilitated by an SI leader who has already mastered the course material and has been trained to facilitate group sessions where students can meet to improve their understanding of course material, review and discuss important concepts, develop study strategies and prepare for exams. SI is for everyone, and open to all students enrolled in this class; not just those students who are struggling. Attendance at SI sessions is free and voluntary. Students who attend SI sessions weekly typically earn higher final course and exam grades than students who do not participate in SI. Please bring your lecture notes, books, and questions with you to the SI sessions.
The schedule for SI study sessions for this class are available by clicking on the Supplemental Instruction link on the left-hand navigation on the Blackboard home page. For additional information about SI, please visit: www.youtube.com/watch?v=-ww-cL75xhQ

The Book, and Other Resources
Required Text and Reading Materials:
Introduction to Linear Algebra (fifth edition), Gilbert Strang, Wellesley-Cambridge Press / Society for Industrial and Applied Mathematics, 2016, ISBN-10 0-980-23277-5, ISBN-13 978-0-980-23277-6
Errata: None known.
Course Outline (Topics)
Transformations, Subspaces of ℜn and Their
Dimensions, Orthogonality and Least
Squares, Determinants, Eigenvalues and Eigenvectors, 8–Symmetric
Matrices and Quadratic Forms.
Alternative Editions of The Book?!?
"Can I Use a Different Edition of the Book?" — Probably, but the 5th edition is a MAJOR OVERHAUL from the 4th...
In particular, the lecture slides!
The Textbook Costs 250+ Tacos!
(Spring 2017:) I have adopted a new text book
[Gilbert Strang's Introduction to Linear
Algebra, Fifth Edition (2016)], which not only is supposed to be
better, but it is also less expensive than the old one. ($86.25*
Campus Resources and Information
Math Learning Center
The SDSU Math Center is in the Love Library, Room
LL-328. The goal of this center is to provide a central location
for students from all lower division mathematics and statistics
courses to find free, on-demand tutoring. We encourage students
who have any questions about their work to drop in for one-on-one,
group, or class-based workshop instruction with tutors who know
the topics, the instructors, the online homework systems, and the
best ways to study.
Students with Disabilities:
If you are a student with a disability and believe you will need accommodations for this class, it is your responsibility to contact Student Disability Services at (619)594-6473. To avoid any delay, please contact Student Disability Services as soon as possible. Please note that accommodations are not retroactive, and cannot be provided until an accommodation letter from Student Disability Services is received by the Professor.
As of Spring 2016, Crashing has been replaced by the Waitlist. Note that professors have VERY LITTLE power over the waitlist, most of the action is "automatic."
General Course Information
Matrix algebra, Gaussian elimination, determinants, vector spaces, linear transformations, orthogonality, eigenvalues, and eigenvectors.Prerequisites
Mandatory problems collected online using WeBWorK. Approximately one assignment per chapter (8-10 assignments). [details TBA]
Recommended problems (not collected) will be also be assigned.
The WeBWork problems are somewhat simplisitic — solving only these problems WILL NOT prepare you for the exams! Do attack the "suggested problems" – they are suggested for a reason! (And do check out the learning glass video solutions)
Syllabus / Schedule Modifications
I reserve the right to modify the syllabus / schedule as needed to work around unforseen events, etc. Announcements may be sent out via Blackboard; and PLEASE make it a point to regularly check the calendar.
