Here are some useful links for linear algebra:

Text:  Linear Algebra, by Fraleigh and Beauregard, 3rd Edition

Topics:  vectors, matrices, linear systems, linear transformations, vector spaces, determinants, eigenvalues, eigenvectors.   There are many applications of linear algebra to problems in many areas of math and science.  We will look at applications in order to motivate the study of linear algebra.

Homework & class work: Suggested homework problems are given for all sections that we cover in class.  Do as many of these as possible and keep the solutions (include the question as well) in a notebook, a loose leaf notebook is best.  You must be self disciplined to do all of the suggested homework problems and to make sure each one is done correctly.  Remember you learn math by doing it.  Doing all of your homework is essential.  It helps you to practice doing all of the problems so that you can do them quickly enough when the time comes to take a test.  Bring this notebook to my office hours to show me your work and ask questions.  I will ask students to put up the solutions to homework problems on the board in class.  This will count as class work.  Also, during class you will sometimes work in groups and hand in your work.  This will also count as class work.  It is essential that you miss as few classes as possible to get class work credit.

Quizzes: I will give you short quizzes in class, once a week.  The questions will be similar to homework problems from the material covered in the previous week.  I won't give make ups on missed quizzes.  Instead, I drop the 3 lowest grades from the semester.  Look for the quizzes and solutions on our class web page.

• Class work - 50 pts
• Maple assignments - 50 pts
• quizzes - 100 pts
• 3 1-hour exams - 300 pts
• final exam - 200 pts

• total - 700 pts
Technology:  You will find your graphing calculator to be helpful, but not essential for this course.  You will need at least a scientific calculator.  Mathematical software packages are very helpful when performing computations in linear algebra, and they can provide a useful tool when learning it as well.  We will use the Maple software package for this course. Learn more about Maple.  You may have purchased the disk LINTEK with your book.  This gives you a way to practice computations and have your work corrected.  Exercises using LINTEK are given at the end of the homework sections in our text.  You may do as many of these as you like.  They are good practice.

Maple Assignments: Listed below are the Maple assignments for this section of MTH 215.
Begin working on the projects well in advance, as you may find that you have questions.  Please come to my office hours with your questions.  The assignments below will turn into buttons that as soon as they are available.

Time table:  The following time table will be used as a guide.  We may be slightly ahead or behind schedule at any given time.
