Prerequisite: MATH 1352 or concurrent.

Text: Linear Algebra with Applications, 8th edition by S. J. Leon, published by Pearson.

Course Description: Basics of linear algebra: matrices and systems of equations, determinants, vector spaces, linear transformations, orthogonality, and eigenvalues. Some of their applications are presented.

Course Outline:

• Chapter 1 - Sections 1-4, approx. 7 days
• Chapter 2 - Sections 1-3 (cover Cramer's rule briefly), approx. 3 days
• Chapter 3 - Sections 1-6, approx. 8 days
• Chapter 4 - Sections 1-3, approx. 6 days
• Chapter 5 - Sections 1-3, 5-6, approx. 9 days
• Chapter 6 Sec.1-3 (higher order systems in Sec. 2 and exponential of a matrix in Sec. 3 are optional), approx. 4 days

Expected Learning Outcomes: Students develop skill in manipulating with matrices and understand their relationship to linear systems. They understand the concept of bases and vector spaces, as well as, eigenvectors and eigenspaces. In particular, students

• perform basic vector algebra, and compute their bases
• express a linear transformation as a matrix
• perform basic matrix manipulations, and compute the determinant of a matrix
• compute eigenvalues and eigenvectors
• use the Gram-Schmidt process

Methods of Assessment of Learning Outcomes: Assessment of the learning outcomes will be achieved through homework assignments, quizzes, three midterm exams, and a final exam. Attendances also count.

Grading policy: Homework will be assigned and quizzes will be given weekly. Both will count for 25% of the grade. Each lowest score of homework and quizzes will be dropped. There will be three midterm exams in class, each will count for 15% of the grade. The final exam will count for 30% of the grade. All in-class exams are closed-book. No make-up exams are given unless legitimate documents for excuses are presented to the instructor at least a week in advance. Grading Scale: A: 90%-100%, B: 80%-89%, C: 70%-79%, D: 60%-69%, F: below 60%

Homework assignments: Online homework will be assigned though Webwork. Students will receive the instructor's message for login information. Due dates are indicated on each assignment. Students should spend very first week to become familiar with the system.

Calculators: Calculators are allowed in the exams and quizzes.

Attendance Policy: Students must go to lectures and attendance will be taken. If you miss no more than four lectures, a bonus of three points will be added to your final grade.

Examination Schedule:

• Midterm 1: Friday, September 24 (NOTICE OF DATE CHANGE)

• Midterm 2: Wednesday, October 20

• Midterm 3: Wednesday, November 17

• FINAL EXAM: 10:30 a.m. – 1:00 p.m., Saturday, December 11

Critical Dates:

• August 26, Thursday: Classes begin.
• September 6, Monday: Labor Day. University holiday.
• September 13, Monday: Last day to drop a course and receive a refund.
• October 11 – 12, Monday – Tuesday: Student holiday; does not apply to School of Law.

• November 24 – 28, Wednesday – Sunday: Thanksgiving holiday.
• December 2 – 8, Thursday – Wednesday: No examinations.
• December 8, Wednesday: Last day of classes.

Academic Misconduct: Academic dishonesty is intolerable and will be punished to the full extent allowed by the University policy.

Civility in the Classroom: Students are expected to assist in maintaining a classroom environment that is conducive to learning. In order to assure that all students have the opportunity to gain from time spent in class, unless otherwise approved by the instructor, students are prohibited from engaging in any other form of distraction. Inappropriate behavior in the classroom shall result, minimally, in a request to leave class.

Students with Disabilities: Any student who because of a disability may require special arrangements in order to meet course requirements should contact the instructor as soon as possible. "I would appreciate hearing from anyone who has a disability that may require special accommodations. I am sure we can work out whatever arrangements are necessary. Please see me during my office hours."

Advice: Come to class regularly, work on homework problems. Ask questions in class and get help from the instructor during the office hours. Master the material quickly and do not wait too late until the midterms or the final exam. Students are encouraged to give feedbacks to the instructor during the semester using the form posted online.

NOTE: When needed, the instructor will communicate with the students using their TTU email addresses. At the beginning of the semester, the instructor will send out a message to confirm the students' email addresses and to inform about Webwork. If a student does not receive any messages by the time of the third class, he/she must contact the instructor immediately.
