Math 22AL and Additional Resources
Many of you are required to take Math 22AL and are taking it this quarter. This info sheet is a must read for those of you taking that course.

Everyone should also know that there are 22A workshops and daily drop-in tutoring available at the Student Academic Success Center. Please go to for more information.


The textbook we'll be using is "Introduction to Linear Algebra" by G. Strang, 5th Edition. If you have an earlier edition, it is your responsibility to figure out the differences to the 5th. Most relevant are the problems at the end of each section.

Homeworks, Exams, and Grading:
Your grade for the course is determined as follows: The exams will be closed book and closed note. A sheet of some useful formulas will be included in each exam, and it will be posted ahead of time on this website. Electronics of any kind (calculators, phones, laptops, etc) are prohibited. Anyone seen to be using a cellphone during an exam will receive a 0 on the exam. There will be no make up exams.

Homework (along with occasional supplementary notes) will be posted here every Tuesday and will be due the following Tuesday. I encourage you to submit your homework as a pdf on Canvas by scanning it using a scanner on campus or a scanner app on your phone. If you do not do it this way, you can hand in a physical copy into one of our homework boxes in the Math Sciences Building on Tuesday by 4PM, located in a hallway just on the West side of the Calculus room. Solutions will be posted on Canvas every week.

Our midterms will be in class on Friday, January 31st and Friday, February 21st. More details about these exams will be announced in class and posted here closer to the dates.

Our final exam code is M. It will take place in our classroom on Wednesday, March 18th, 1-3PM.

If you need special accommodations for the exams, these accommodations must be documented through the Student Disability Center in order to be valid.

Basic Plan:

We will cover most of the first six chapters from the textbook. For a detailed syllabus as suggested by the department of mathematics, please click here.

Our goal, in a nutshell, is to learn the basics of linear algebra: vectors, vector spaces, matrices, systems of linear equations, eigenvalues and eigenvectors. This topic is at the core of many facets of science and engineering, not to mention many fields in pure and applied mathematics.

Detailed Plan:

The following is a rough outline of what we will be doing in lecture every day, along with the relevant sections in the book (note that the reading for a given lecture should be taken to mean the relevant section of the mentioned chapter). In reality, we may move faster or slower. It will be updated on a regular basis.
