Sediq 2012/2013 Soran University Faculty of Science Department of Mathematics Stage 2 Welcome to department of mathematics at Soran University. This handbook summarise all the general information you need to guide you during the second stage of your selected course. This booklet also describes in details the content of linear algebra unit, the names of academic staff who will teach the unit, and what you will be expected to do to make sure your success in this unit. We hope you enjoy the unit and that you will find the work inspiring and challenging. Keep in mind that good attendance at lectures and tutorials is important to give you a good basis for work throughout the course. If any students may experience difficulty with this unit, is important to sort things out as soon as possible. Make an appointment with unit coordinator who may be able to help, your year tutor, or other academic staff that involved with this unit. Please note: you are provided with a hardcopy of teaching materials. It may be necessary to change the order of lectures, deadlines etc, which you will be informed. Therefore, it is ESSENTIAL that you check the Department of Mathematics notice board regularly in order to keep up to date with any changes. Course Overview and Goals This is a basic subject on matrix theory and linear algebra. Emphasis is given to topics that will be useful in other disciplines, including systems of equations, vector spaces, determinants, eigenvalues, similarity, and positive definite matrices. The class is primarily based on Chapters 1-7 of Lay's book: “Linear Algebra and Its Applications (4th Edition) (David C. Lay)”. Learning Outcomes After successful completion of this course, the student will be able to: * Solving Ax = b for square systems by elimination (pivots, multipliers, back substitution, invertibility of A, factorization into A = LU) * Complete solution to Ax = b (column space containing b, rank of A, nullspace of A and special solutions to Ax = 0 from row reduced R) * Basis and dimension (bases for the four fundamental subspaces) * Orthogonalization by Gram-Schmidt (factorization into A = QR) * Properties of determinants (leading to the cofactor formula and the sum over all n! permutations, applications to inv(A) and volume) * Eigenvalues and eigenvectors (diagonalizing A, computing powers A^k and matrix exponentials to solve difference and differential equations) * Symmetric matrices and positive definite matrices (real eigenvalues and orthogonal eigenvectors, tests for x'Ax > 0, applications) * Linear transformations and change of basis (connected to the Singular Value Decomposition - orthonormal bases that diagonalize A) Communications with Academic Staff This handbook gives information on how to contact and communicate with staff. We provide room numbers and email addresses of staff to you. The staffs in this department want to help you as much as possible so that you will be successful in your programme. We also want to encourage you to take responsibility for yourselves and for your learning so it will help you in your future careers. The email rules * Write your email in acceptable English. * In your emails you must include: full name, stage, department and the unit title. * We only respond to queries from students using genuine/Soran University email accounts. * Appointments can be arranged through the email system, if you wish. * We respond to genuine problems and queries as soon as possible, normally within 7 days. * We will not respond to emails which do not have a subject line.
