During your tutorials the T.A. will discuss with you some problems from the list below. Feel free to ask questions about the problems you have difficulty with.

Remarking Procedure
Your tests will be returned to you in the tutorial section in which you are registered as soon as they are marked. If you have any questions about the marking of your test, you will have to return your test to your T.A. within 10 min indicating on the front page which question you want to be remarked. If you take your paper with you, no one will look at it again. No test will be remarked unless the original answers were written in ink.

Brief Description
This is the second course in Linear Algebra, that is more theoretical in nature then your first course (Linear Algebra I - MAT223). The course will cover: abstract vector spaces, linear mappings, linear operators on both real and complex vector spaces, inner product spaces, orthogonal (unitary) diagonalization of linear operators, isometries. It will be assumed that you know basic material from Linear Algebra I, particularly: matrix arithmetic, similarity and diagonalization of matrices and the basic concepts of the n-space R^n including orthogonality.
