Text  Linear Algebra and its applications, by David C. Lay, 3rd Edition, Pearson/Addison Wesley 
Prerequisites  MTH 142 or MTH 131 
Topics  We will study selected sections from the following chapters: Linear equations in linear algebra, matrix algebra, determinants, vector spaces, eigenvalues and eigenvectors, orthogonality and least squares. For more details see the Calendar and Suggested Problems 
Evaluation  There will be 2 exams given during normal class time, on the following dates: Wed. Feb. 27th, and Wednesday, Wed. Apr. 9th. Your grade will be calculated according to the following weights: Final Exam (33%), Exams (33%), Assignments (33%) Here class work includes homework, quizzes, Maple projects, and special assignments. 
About the Course  This is an undergraduate course in Linear Algebra for students of engineering, science and mathematics. Linear Algebra is the study of linear systems of equations, vector spaces, and linear transformations. Solving systems of linear equations is at the heart of virtually every mathematical procedure for solving problems arising in science and engineering. In this class we will concentrate on the mathematical theory and methods of linear algebra. 
Homework  Homework will be assigned after each section from the list of problems found in Calendar and Suggested Problems . Your homework should show your work, short answers are not acceptable unless it is obviously what is being asked. Homework questions will be answered at the beginning of class. You may also send email your instructor with questions at merino@math.uri.edu. 
Technology 
We expect that you have a graphing calculator and are familiar with its use. A TI83 or equivalent is fine. Calculator use may be restricted on some exams since more advanced calculators, like the TI89 can do some of the computations that we expect you to learn to do with just pencil and paper. We will use Maple in this class, and some Maple assignments will be collected.
