Linear Algebra Roughly speaking, linear algebra is the study of an algebraic structure consisting
of a set together with a notation of "linear combination" of its elements, and more
of a "linear transformation" between two such structures. In particular, an equation
is called linear if it is of degree one, and for a linear equation with only one variable,
its graph is a line, hence the term "linear".
This subject is useful because it is suited for dealing with a large percentage of
real world problems that are either linear or regarded as almost linear. We shall
see some concrete examples in the first few chapters and then move on to the more
abstract objects and concepts in this field.

PowerPoint Lecture Notes
Course Prerequisite: The basic requirement is a grade C or better in Math 280, but the successful completion
of Math 245 will be recommended.
Calculator requirement: You will need a calculator or computer software that can perform moderate to advanced
matrix operations to survive in this class. The reason is that most homework and exam
questions will require large amount of calculations which cannot be performed by hand
in the given time period.
The TI82, 83, 86, 92 or more advanced version will work. You will get better results
if you have access to the softwares Maple, Derive, or Mathematica etc. (These should
be available in our Math Study Center, please go there and ask.)
Grades: This course is offered for a grade of A, B, C, D, or F. The grade distribution is
||90 - 100%
||80 - 89%
||70 - 79%
||60 - 69%
||00 - 59%
|5 short quizzes @25 pts
|2 one-hour exams @100 pts
Homework will be assigned at the end of each class meeting, and if you are eager to
do the exercises in advance, you can get the assignment from the next webpage (see
top of page).
Expectation of Students:
- Attend all classes and take notes.
- Read the text book before and after each lecture. There is so much material to be
covered in this course that it is impossible for the lecturer to include all the details
- Work out the details and fill in the steps at home for the examples discussed in class.
You cannot expect to understand everything instantly during lecture hours because
the lectures will be conducted in a pace much faster than you have ever encountered.
You can only expect to grasp the main ideas first, and then slowly digest the material
through reading, thinking, and practicing later at home.
- Form study groups with fellow students, work together in the library or outside school.
This is the best way to learn and check your understanding.
- Do all assigned homework problems on a daily basis. Work out the details and aim for
Any student who cheats on any of the tests, or disrupts the class or hinders the progress
of any other student will be dropped from the class, and his/her misconduct will be
stored in Grossmont College's record.
