Linear Algebra

I.     Course Prefix/Number: MAT 260

       Course Name: Linear Algebra

       Credits: 3 (3 lecture; 0 lab)

II.    Prerequisite

MAT 251 with minimum grade of C.

III.   Course (Catalog) Description

Course covers matrices and the algebra of linear systems.  Content includes equations, vector spaces, real inner product spaces, linear transformations, determinants, eigenvalues, eigenvectors, diagonability, quadratic forms and symmetric matrices.  Calculators/computers used when appropriate.

IV.   Learning Objectives

  1. Apply basic matrix methods to solve systems of linear equations. Determine whether the equations are linearly independent and how that affects the solution.
  2. Apply course content to applications which may include topics such as Kirchoff’s laws, Leontieff economic models, Markov chains, least squares methods, image processing, and statistics.
  3. Apply algebraic methods to construct, analyze, and evaluate the following features of linear transformations: matrices and factorizations, one-to-one, onto, range, column space, null space, and similarity.
  4. Calculate determinants, cofactor expansions, eigenvalues and eigenvectors. Use diagonalization to compute bases for an eigenspace.
  5. Apply the definitions of vector space and subspace to establish coordinate systems and a change of basis.
  6. Calculate bases, dimension and rank of a matrix, use inner products to find lengths, projections, angles between vectors and to determine linear dependence or independence of a set of vectors.
  7. Use the Gram-Schmidt process to find an orthogonal basis for a vector space.
  8. Use symmetric matrices and diagonalization to classify quadratic forms and find a basis for which a quadratic form has no cross-terms.

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at

(To be completed by instructor)

Course may be taught as face-to-face, media-based, hybrid or online course.

IX.   Instructional Materials

Note: Current textbook information for each course and section is available on Oakton's Schedule of Classes.

Within the Schedule of Classes, textbooks can be found by clicking on an individual course section and looking for the words "View Book Information".

Textbooks can also be found at our Mathematics Textbooks page

A computer algebra system is required.

X.    Methods of Evaluating Student Progress

(To be determined and announced by the instructor)

Evaluation methods can include grading homework, chapter or major tests, quizzes, individual or group projects, calculator/computer projects and a final examination.

The following applies to the online section of this course only.

This online course requires that students take their exams as directed by their instructor: either on campus at Oakton's Testing Center, at an authorized testing center with a face-to-face monitor, or remotely through a pre-approved testing service.   (To be customized by instructor.)

XI.   Other Course Information

Individual instructors will establish and announce specific policies regarding attendance, due dates and make-up work, incomplete grades, etc.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.

Oakton Community College is committed to maintaining a campus environment emphasizing the dignity and worth of all members of the community, and complies with all federal and state Title IX requirements.

Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.

For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.

Violation of this policy will result in disciplinary action through the Code of Student Conduct.
