I am emailing a link of this to everyone on the class list every week. If you are not receiving these emails or want to have them sent to another email address feel free to email me at jpmccarthymaths@gmail.com and I will add you to the mailing list.

Important: Gaussian Elimination

Please look at p.26 Questions 1 & 2 and p.35 Questions (iv), (v) and (vi) only. The other ones are just too messy.

Also if you download Maple (see below), there is a Maple Tutor that is easy to use and will help you. Open up Maple and go to Tools -> Tutors ->Linear Algebra -> Maple Inverses.

Test 1

The test will be on the first Tuesday slot of Week 5. That is Tuesday 25 February at 11:00 in B214. Ye have the test that I gave last year in the notes.

Week 3

We solved some 3×3 linear systems using the techniques of Week 2. We spoke about the determinant of a matrix and covered Cramer’s Rule. This concluded Chapter One.

Week 4

In Week 4 we will begin our study of Chapter 2, Vector Algebra. We will initially take a dual algebraic/geometric viewpoint.


If you have the 09:00 Lab on Fridays your tutorial will be
  • Friday 11:00 in B260
Otherwise your tutorial will be
  • Friday 13:00 in B245

Exam Format

Four questions, do all as in the Winter 2013 paper which can be found by searching through Mathematics here.

Academic Learning Centre

Those in danger of failing need to use the Academic Learning Centre. As you can see from the timetable is quite generous. You will get best results if you come to the helpers there with specific questions.

Math.Stack Exchange

If you find yourself stuck and for some reason feel unable to ask me the question you could do worse than go to the excellent site math.stackexchange.com. If you are nice and polite, and show due deference to these principles you will find that your questions are answered promptly. For example this answer which explains the significance of the determinant.

Maple Online & Wolfram Alpha

If you are subscribed to CIT MathsOnline you will have free access to the mathematical software package Maple:

You can download Maple by selecting the Mathematical Software tab in the left hand column and following the instructions under the Maple item. Click Maple text to start.

I myself am not a Maple expert but ‘grew up’ with another mathematical software package MathematicaMathematica powers the “computational knowledge engine” WolframAlpha. Go on ask it a question!

Additional Notes: E-Books

If you look in the module descriptor, you will see there is some suggested reading. Of course I think my notes are perfect but if you can look here, search for ‘Bird Higher Engineering’ you will see that the library have an E-Book resource.
