MATH 251- Matrix Algebra for Engineers


Mar 21: Test 3 remains scheduled for Friday, April 5. However, the cut-off for that test has been changed to sec 5.2 (instead of 5.3). Section 5.3 onwards will not be covered by Test 3 but will be tested on the final exam along with everything else.

Mar 8: This is a reminder that Wednesday, March 13 is the last day you can withdraw from (or switch to audit in) most Winter 2019 courses (including MATH 251).

Feb 22: The Winter 2019 final exam schedule has been posted on Camlink. See below for details of the MATH 251 final exam.

Feb 16: My regular office hours are cancelled during the Reading Break (February 19-22) due to various meetings and appointments. Please email me if you have any questions or if you wish to book an appointment to meet in person.

Feb 11: Camosun college will be closed on Tuesday, February 12 due to the snow. Upon a return to classes, we will resume coverage of sec 3.4 on LU factorizations.

Feb 4: Recent light snow in Victoria reminds us of the possibility of inclement weather. In the event of severe weather conditions, the college may close. Information about college closures due to severe weather can be found here.

Jan 16: This is a reminder that Monday, January 21 is the fee deadline and the deadline for dropping classes with a full tuition refund.
