Course Description: This course meets the quantitative reasoning requirement, one of the Foundation requirements of the University General Education program. The goal of the Foundation requirement is to help ensure that students are equipped with the tools and techniques necessary to succeed in college and throughout their lives and careers.
We will cover the following topics :

  • Linear Equations
  • Linear Systems and Matrices
  • Leontief Input/Output Analysis
  • Markov Processes
  • Data Fitting - Polynomial Interpolation, Least Squares
  • Difference Equations

Exam Dates:

  • Test 1: Monday February 21
  • Test 2: Monday, March 28
  • Test 3: Monday, May 2
  • Final Exam: Wednesday, May 11, 1:30-4:15
There will be NO MAKE-UP tests or quizzes. If you miss an exam or quiz, contact me ASAP!

Grading: Your grade for the course will calculated based on three exams, four sets of Matlab problems, five quizzes and a final exam. The Matlab assignments are worth 25 points each (total 100 points) , quizzes are 10 points each, tests are each worth 100 points and the final exam is worth 150 points. The sum of these grades divided by 6 determines your grade according to the scale:

A: 90-100   B:80-89.9  C:70-79.9   D:65-69.9   F: below 65
+ or - will be attached ( if applicable) to the grades that occur in the lower or upper 2 points of each category.

Homework: Homework problems will be assigned at the end of each class and reviewed at the beginning of the next class meeting. Reading the sections of the text related to the problems is part of the homework assignment. Assigned problems will be posted after each class. There is also a link to the homework assigments at the top of this page

Calculators: You are welcome to use calculators for class work, homework, and exams. Our textbook includes notes on the use of TI-83. You are not required to get this particular calculator but if you have one, feel free to use it. Matrix calculations on exams are to be done by hand

Computers: We will be using Matlab to help with matrix calculations. This software is available for student use either on campus or remotely on mason.gmu.edu. The system requires your PatriotPass. If you have not activated it go here:


There are computer Labs in Innovations Hall, the Johnson Centerin rooms 340, 341, and 343. For hours of operation of these labs and other locations see
Academic Computing Labs

Honor Code: Sharing information about exams of any kind will result in a grade of zero. The Matlab assignments are NOT group projects. Each student is to work independently at the computer terminal and hand in his or her own computer printout. Any violations will result in a grade of zero for all students involved.    See the GMU Honor Code

Disability statement: If you are a student with a disability and you need academic accommodations, please see me and contact the Office of Disability Resources at 703.993.2474. All academic accommodations must be arranged through that office.

Tutoring Center: The Math Tutoring Center is located in the Johnson Center Rm 344. Help is available on a walk-in basis.
For current hours see Math Tutoring Center.

General Remarks: Please be considerate of other students.
Please get to class on time. If you must arrive late or leave early sit in the back near the door to minimize the distraction.
Please turn off your cell phone before class.
My responsibility as the instructor of this course is to answer questions and organize the material in a logical manner to facilitate learning. Your job as the student is to attend every class, arrive on time and be attentive, meet deadlines and be responsible for your learning.
