Math 45 - Linear Algebra

Syllabus

Instructor: David Arnold

Prerequisite Classes

The prerequisite classses for linear algebra are college algebra (Math 30) and trigonometry (Math 25). However, it is highly likely that the majority of students in linear algebra have also completed the first course in calculus (Math 50A) or are coenrolled in Math 50A. I will informally poll the class on this first day so that you can view the competition.

Office Hours

You can find a copy of my schedule, including office hours, here. Note: These are "official" office hours. However, I will make myself available whenever I can. Please do not be afraid to ask for help at any time as I am always eager to help.

Office Location and Phone

Cancelled Classes

Those driving long distances to attend classes are advised to call 476-4210 before driving to the CR campus. Choose #5 from a menu of choices. You will then be advised of any cancelled classes for the day in the Physical Sciences complex (math/science). Thus, you can avoid the frustration of driving to campus, only to find that your class has been cancelled.

Click the Blackboard icon that follows. This will initiate contact with BlackbBoard. Read the Student Introduction, User Name and Password, and Getting Help sections. Be sure to write down your login name and password for future reference. Once you login to Blackboard, locate your math class and take some time to find out what is provided. In particular, you'll want to update your personal information, especially your email address. Then read the "welcome message" in the Discussion Board and reply to this thread. In the future, use the Discussion Board to discuss issues and problems you are having with your class.

Computing Resources

The Eureka campus houses computing facilities for its linear algebra students. They are located in the physical sciences building, room PS116. There are a number of powerful software packages on the machines in this room that will aid in the study of linear algebra. See your instructor for login name and password.

Transferring Files to and from the Department Server

Along with your username and password, which allow you to log on to computers in the Math/Science/Engineering computer labs and print your class assignments, you are granted some file storage space on the Math department's file server, MSEMac, which allows you to save files files and access them at school as well as at home. Using the server to store and back up your class files will help ensure that you are always up-to-date on your assignments, will let you work on projects in multiple places, can guard against computer failure, and lets you transfer files from campus and back without needing a memory stick.

The process for connecting to MSEMac is different for Macs and PCs (the former is somewhat simpler). If you have a Mac, please read our guide to connecting to MSEMac for Macs, and if you have a PC, please read our guide to connecting to MSEMac for PCs.

Computer Lab -- Code of Conduct

Please see labconduct.html for a set of rules and guidelines for computer use and maintaining decorum in the study rooms available in the physical sciences building.

Calculators

We will use Matlab to perform most of our calculations, so calculators are not an integral part of the course. Whatever calculator you currently own will probably be fine for this course.

Matlab

Matlab is a powerful software package created by the engineers at the Mathworks. Matlab software can be installed on several platforms, including Windows XP, Linux, and Mac OSX.

If you do not have a computer capable of running the Matlab software, then you can take advantage of the computing power located in rooms PS116 and PS118. Matlab is installed on each of these machines for use by students in differential equations.

You can also purchase the student edition of Matlab 7 here. Please check here to see if your system has adequate hardware to run this release of Matlab. A number of copies of the Student Edition of Matlab 7, Release 14, are available in the bookstore.

The best source I know of for learning Matlab 7 is Mastering Matlab 6 which can be purchased online. This text is accompanied with a host of great programs that are available here.
 

Exams and Quizzes

Over the years, I have become more and more frustrated with the approach that students take in their studies. Typically, when students know an exam is coming up, they put on hold studies in their other classes to "cram" for the upcoming test. This is perfectly understandable and I freely admit that I did much the same thing when I was a student.

However, this is really not a good way to learn. Often, students are frustrated to find themselves behind in their other classes as they stuggle to prepare for an exam. They are unable to participate in lectures and they cannot follow the material in class because they are sections behind in their work. This is also frustrating for the teacher as he often winds up talking to himself during lecture.

Consequently, I've decided that this semester I am not going to give any examinations at all in Math 45. Instead, I will give "weekly quizzes" for you to work on which will be graded carefully.

Homework

"Daily homework" will be assigned each class and is due the next class period. Each "daily homework" assigment is worth 10 pts. I will scrutinize your work rather quickly, noting whether it is complete and whether you are following all directions given on the assignment. A score ranging from 0-10 points will be awarded.

There is a "grace period" on "daily homework" of one class period. This means that I will allow homework that is late by one class period, but no later. Any homework that is turned in after the "grace period" will receive no credit. Two points will automatically be deducted for any homework that is turned in using the "grace period."

In order to facilitate the grading of "daily homework," students are required to place their name in the upper right-hand corner of their homework assignment and staple the pages together with a single staple in the upper left-hand corner. On the first line of the paper, please write down the assignement number, the pages that encompass the assignement, and list each exercise number assigned. For example, the first line of your homework might read:

Assignment #12, Page 150, #1, 3, 5, 7, 8, 10, 11, 23, 45

Student Projects

Each student in linear algebra is required to create a linear algebra project. This project will take the place of the final examination in linear algebra. The class will meet during the final examination period when students will present their projects.

Project Requirements

Here are a few guidelines for student projects. Some thoughts on your presentation.

Grades

To determine your grade in the class, points from homework, "weekly quizzes," and the project will be totaled, then weighted and curved to determine a final grade in the class.
