TEXTBOOKLinear Algebra and its Applications, 5th ed. by D.C. Lay, S. R. Lay and J. J. McDonald  

COURSE PREREQUISITES: Two semesters of calculus

COURSE OBJECTIVES: The course is all about methods for understanding the properties of solutions of linear systems of equations and related problems involving matrix relationships, and techniques for calculating solutions. The emphasis in this course is on methods and techniques -- MATH 317 covers many of the same topics but with emphasis on the underlying theory. A detailed listing of textbook sections to be covered and course objectives is given here.

MAIN COURSE CONTENT

COURSE GRADE:
 
Three in-class exams   20% of grade each
Homework   10% of grade
Quizzes
10% of grade
Final Exam 20% of grade

An overall score of 90% or better guarantees at least an A-; 80% or better guarantees at least a B-; 70% or better guarantees at least a C-; 60% or better guarantees at least a D. These thresholds might be lowered at the end of the semester. No individual assignment grades will be curved.

HOMEWORK
: The MyLab Math online homework system will be used for most of the homework. Working these problems in a careful and timely manner is the most important way you have to learn the material. Normally a new assignment will appear on the day of each lecture in which new material is covered, and due 7 days later.  It is fine to discuss the homework with other students, but the homework answers you submit should be the result of your own work. 
Click here for a few more details about MyLab Math. A little class time will be taken around once every week or two to go over some of the assigned homework.      

QUIZZES: There will be ten quizzes given, each taking up about the last 10-15 minutes of class, on the Friday of each week except the first and last week and the exam weeks. The lowest two of these ten scores will be dropped.

EXAMS: There will be three midterm exams taking place during the regular class periods on the Friday of weeks 5, 9 and 14, that is to say, February 15, March 15 and April 26. Exam problems will be similar to homework problems. I will clarify a week or so ahead of time exactly what topics will be covered on each exam. Policies concerning make-up exams will follow the general Mathematics department guidelines. Time and place for the final exam will be announced when available.

CLASS ATTENDANCE: Although attendance will not be taken, regular attendance is normally a prerequisite for success. Office hours are for those of you who need additional help beyond that given in the class; they are not substitutes for class. 

DEAD WEEK (April 29-May 3): The last one or two of the daily homework assignments will come due during this week.

CALCULATORS: Calculators are allowed, but not required, on quizzes and exams unless otherwise stated. During quizzes and exams you may not use a calculator which is also a communications device.  Calculators are meant as a convenience for the routine aspects of problem solving, but not as a replacement for the understanding of the concepts and methods which make up this course. As in any other mathematics course you should expect to have to demonstrate your competence by showing your work.

ELECTRONIC DEVICES: Cell phones and other communications devices should be turned off during class time. In the event that a student needs to keep his/her cell phone on for an emergency, please exercise suitable discretion to avoid disrupting the class. During class time, laptop computers or tablets should only be used for class appropriate purposes.

ACADEMIC HONESTY:  Academic dishonesty is very serious. Any case of cheating, plagiarism, etc, will be handled as described in the Student Disciplinary Regulations.

OTHER RESOURCES: Course information and announcements can  be found via Canvas where you can also keep track of your grades.
