Course Description: MAT 331, Elementary Linear Algebra,
covers Chapters 14, 67 from the textbook: linear equations,
vector spaces, matrices, linear transformations, determinants, eigenvalues,
eigenvectors, etc.
Text: Elementary Linear Algebra, by
Keith Matthews, available online at http://www.numbertheory.org/book/
Objectives: After completing MAT 331 the student should be able to: solve systems of linear equations; add, multiply matrices, find the inverse of an invertible matrix; evaluate determinants; work with vectors, identify bases of vector spaces, find eigenvalues and eigenvectors of linear transformations.
Prerequisites: MAT 271 or equivalent with a grade of "C" or
better.
Grades: Grades will be based on three in‑class full period
examinations (60% total), a comprehensive final examination (25%), and quizzes,
homework, attendance and other assignments (15%) for the remainder.
The exact grading system for your section is the following:
Each of the three
full period exams will be graded on a 100 scale, then the sum of the scores
is divided by 5 and denoted by E.
Homework will be due every Monday, and
each homework is worth 5 points. No late homework will be accepted. The average
of all homework scores is denoted by H.
5 to 10 minutes
quizzes will be
given in principle every Monday, and will be graded on a scale from 1 to 5. The
average of the quizzes scores is denoted by Q.
There are also 5 points awarded for attendance and class participation. This portion of the grade is
denoted by A.
The final exam
will be graded out of a maximum possible 200, then the score is divided by 8
and denoted by F.
To determine your final
grade, compute E+H+Q+A+F. The maximum is 100, and the grade will be given
by the rule:
A: 93‑100; A‑: 90‑92; B+: 87‑89; B:
83‑86; B‑: 80‑82
C+: 77‑79; C: 73‑76; C‑: 70‑72; D+:
67‑69; D: 60‑66; F: Less than 60.
Makeups: No makeup examinations or
quizzes will be given. If you must miss an examination for a legitimate reason,
discuss this, in advance, with me, and I may then substitute the relevant score
from your final examination for the missing grade.
Accommodations
for Students with Disabilities: Cal State Dominguez Hills adheres to all applicable federal,
state, and local laws, regulations, and guidelines with respect to providing
reasonable accommodations for students with temporary and permanent
disabilities. If you have a disability that may adversely affect your work in
this class, I encourage you to register with Student disAbility Resource Center (SdRC)
and to talk with me about how I can best help you. All disclosures of
disabilities will be kept strictly confidential. Please note: no accommodation
may be made until you register with the SdRC in WH
D180. For information call (310) 2433660 or to use telecommunications Device
for the Deaf, call (310) 2432028.
Academic Integrity: The mathematics department does
not tolerate cheating. Students who have questions or concerns about academic
integrity should ask their professors or the counselors in the Student
Development Office, or refer to the University Catalog for more information.
(Look in the index under "academic integrity".)
Exam rules: Students must leave their CSUDH
student ID on their desk for the duration of the exam. Cell phones, iPhones,
iPods, or PDAs of any kind, as well as headphones, may not be used at all
during a test. Students are discouraged from leaving the exam room during the
period of the exam. Restroom breaks must be kept under five minutes and are
limited to one/exam. You will be penalized 5 points if you are gone more than
five minutes. No more than one student can be out of the room at any given time
during an exam. If a student finds it necessary to leave the room under these
circumstances, they are not permitted to access computer terminals, smoke, read
notes/books, or talk with others. If a student is found engaging in this
behavior, appropriate disciplinary action will be taken. Whenever a student
leaves the room, they must turn their exam upside down on their desk. All book
bags or similar items will be deposited in the front of the class for the
duration of the test.
