TEXTBOOK Linear Algebra and its Applications, 4th ed.,  by David C. Lay

COURSE CONTENT:

• Linear equations (Chapter 1)
• Matrix algebra (Chapter 2)
• Determinants (Chapter 3)
• Vector spaces (Chapter 4)
• Eigenvalues and Eigenvectors (Chapter 5)
• Orthogonality and least squares  (Chapter 6)
In some cases these chapters will be covered quite thoroughly and in others only selected topics will be discussed.

 Two hour exams 25% of grade each Quizzes and homework 20% of grade Final exam 30% of grade

UNGRADED HOMEWORK: Assignments from the textbook will be made for each class, which are not meant to be handed in. Working these problems in a careful and timely manner is the most important way you have to learn the material. Click here to get an up-to-date list of homework assignments. A little class time will be taken from time to time to go over some of the assigned homework. If you want to request that a certain problem be discussed, let me know ahead of time by e-mail.

GRADED HOMEWORK: Selected problems from the textbook and from other sources will be collected for grading. Click here for homework assignments to hand in.

EXAMS: These will take place during the regular class period on October 2  and November 6 (both Wednesdays).  Exam problems will be very similar to homework problems. I will clarify a week or so ahead of time exactly what topics will be covered on each exam. The final exam time will be posted here as soon as it is available.

CALCULATORS: Calculators of  four function, scientific, or graphing type are allowed, but not required, on quizzes and exams unless otherwise stated. You may not use a calculator which is also a communications device or which has a built in computer algebra system.  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 on anything which gets graded.

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 notify the instructor before class. During class time, laptop computers should only be used for class appropriate purposes.

OTHER RESOURCES: Course information and announcements can also be found via Blackboard Learn where you can also keep track of your grades. Click here for Mathematics department syllabus and class policies, including policies about make-up exams.

If a student has a disability that qualifies under the Americans with Disabilities Act and Section 504 of the Rehabilitation Act and requires accommodations, he/she should contact the Disability Resources (DR) office for information on appropriate policies and procedures. DR is located on the main floor of the Student Services Building, Room 1076; their phone is 515-294-7220.
