## Manuals

Please get your manual ASAP from the Copy Centre. They are priced at E12.

## Week 1

After introductions, we looked at matrices and we introduced the idea of a matrix inverse.

## Week 2

We will learn how to find the inverse of a 3×3 matrix using Gaussian Elimination.

## Test 1

Provisionally I am looking at Week 5. Ye will get a sample test (format *only*) and notice two weeks in advance.

## Exam Format

Four questions, do all as in the Winter 2013 paper.

## 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 question which asks why do we define matrix multiplication like we do.

## Maple Online & Wolfram Alpha

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

**Self-enrolment for Maths Online**

1. Log into Blackboard Learn

2. Click on the Courses tab button at the top of the screen. Go to Course Search and type Maths Online in the box.

3. Once you’ve found the course, click on the action link button next to the course and click on Enrol. This should take you to the Self Enrolment page.

Once you’ve enrolled, you can download Maple by selecting the *Mathematical Software* tab in the left hand column and following the instructions under the Maple item.

I myself am not a *Maple *expert but ‘grew up’ with another mathematical software package *Mathematica*. *Mathematica *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.
