 Welcome to MATH2040C. There is no tutorial on week 1.
 Tutorial ID: 993 5417 3106; Passcode: 2040tut
 Homework 1 has been posted. The question can be found in the textbook: Friedberg, Insel and Spence, Linear algebra, 4th edition, Pearson. Please submit your homework on the Blackboard. It is due on January 25 before 11:59pm.
 Midterm 1 will be conducted online as a "takehome exam" with 24 hour limit. It will be posted on Blackboard at 5pm on Feb 25 and the deadline for submission is 5pm on Feb 26. It is expected that the paper can be finished within an hour. As such, the 24hour limit should allow enough flexibility. The exam will cover materials up to "Change of Coordinates" (Topic 19 in the course notes, or up to Section 2.5 in the textbook). It is an opennote exam; however, discussions with anyone are strictly prohibited. Late submission will not be accepted.
 Midterm 2 will be conducted online as a "takehome exam" with 24 hour limit. It will be posted on Blackboard at 5pm on Mar 25 and the deadline for submission is 5pm on Mar 26. It is expected that the paper can be finished within an hour. As such, the 24hour limit should allow enough flexibility. The exam will cover materials up to "CayleyHamilton Theorem" (Topic 112 in the course notes, or up to Chapter 5 in the textbook). It is an opennote exam; however, discussions with anyone are strictly prohibited. Late submission will not be accepted.
 The final exam of MATH2040 will be conducted online on May 3 Monday afternoon. The exam will start at 12:30 pm, and the question paper will be uploaded to Blackboard and the course website on time. The duration of the hour is 2 hour, and you will be given 15 minutes to submit your answer scripts. That means the very strict deadline of submission is 2:45 pm. Late submission will not be accepted. (In case you encounter technical problems when submitting the answer scripts, please contact me immediately.) The exam will cover all taught materials of the textbook, or equivalently, all topics in the course notes (from MATH2040A). It is an opennote exam; however, discussion with anyone is strictly prohibited.

Course Description
This course is a continuation of Linear Algebra I (MATH 1030). It is a second course on linear algebra and will cover basic concepts of abstract vector spaces, linear transformations, eigenvalues and eigenvectors, diagonalizability, operators on inner product spaces, orthogonality and GramSchmidt process, adjoint, normal and selfadjoint operators, spectral theorems, and if time permits, quadratic forms and Jordan canonical forms. More emphasis will be put on the theoretical understanding of basic concepts in linear algebra.
