## Test 1

As I said in Tuesday’s lecture, I was a little concerned to see so many people still writing when time was up.

I said that the test is normally 55 rather than 50 minutes long (due to restrictions placed on me by the Exams Office (that I subsequently saw were unnecessary)), but that I had thought I had adjusted the test appropriately.

There are two main reasons why people might have been still writing with time up:

- people, primarily due to missing too many classes, were not prepared properly, and/or
- the test was too long

I can apologise unreservedly if it was the case that the test was too long.

How I can I fix this?

First of all, for the second test I will give ye the full hour rather than 55 minutes.

The second thing I will do is look back on last year’s results for Test 1 and look at the average of those:

- with zero attendance warnings
- with one attendance warnings
- with two attendance warnings
- with three attendance warnings

If these differ significantly from this year’s averages, I will adjust upwards the marks appropriately.

If I don’t see a significant difference I am going to put the fact that people were still writing with no time left as primarily down to them not having prepared properly for the test.

## Week 6

We had the test on Monday and this meant we could not start a review of differentiation. On Tuesday we looked at Cramer’s Rule, and then on Thursday we did one more question followed by a Concept MCQ on Matrices.

I actually have videos from last year if you missed some classes from Week 6:

## Week 7

We will start Chapter 3 with a review of differentiation followed by a look at Parametric Differentiation.

If you want to look ahead here are two videos:

## Test 1

Test 1, worth 15%, takes place from 16:00 to 16:50 sharp, Monday 14 October in the Melbourne Hall (rows I-K). I will have emailed your 15:00-16:00 lecturers so that they will leave you plenty of time to get to the Melbourne.

There is a sample on P.46 of the notes to give you an idea of the length and layout only.

Almost everything in Chapter 1 is examinable. Additional practise questions may be found by looking at past exam papers (usually vectors are Q. 1, sometimes Q. 2).

You will want to be familiar with all the concepts in the Vector Summary, P. 42-45.

You can check your work against the Sample Test Marking Scheme.

Any questions at all, you can email me, perhaps with a screenshot of your attempt. There are also a number of you in the Telegram group which has thus far been silent.

**HINT** (*very* rare): Look at “*Vector of a Given Magnitude in a Given Direction*” on p.15-16. Thus, also, Example 3 **Winter 2017 **on p.37-38, Example 4 **Summer 2016 **on p.38, and **Autumn 2018 **on p.39-40.

## Week 5

We look at Matrix Inverses — “dividing” for Matrices. This allowed us to solve matrix equations. We looked at linear systems, and determinants.

## Week 6

We will finish looking at Chapter 2 and then we will start Chapter 3 with a review of differentiation followed, perhaps, by a look at Parametric Differentiation.

**Your timetable is wrong in the naming of this module. MATH6040 is Technological Maths 201 and not Technological Maths 2. You did Technological Maths 2: MATH6015, last year.**

## Week 4

We finished looking at the applications of vectors to work and moments and began Chapter 2: Matrices. We did some examples of matrix arithmetic. Here find a note that answers the question: why do we multiply matrices like we do?

We also did a Concept MCQ to summarise Chapter 1.

## Week 5

We will look at Matrix Inverses — “dividing” for Matrices. This will allow us to solve matrix equations. We will look at linear systems, and possibly determinants.

## Telegram App

For those who have already contacted me, I hope to have this set up for Monday.

If this is something you might be interested in, please download the Telegram app and set yourself up with an @ handle.

## Diagnostic Test

I will be in touch with those who have taken the diagnostic test.

## Academic Learning Centre

If you are a little worried about your maths this semester, perhaps after the Quick Test or in general, I would just like to remind you about the Academic Learning Centre. Most students received slips detailing areas of maths that they should brush up on. The timetable is here.

## Week 3

We started working with the cross product and looked at the applications of vectors to work.

We had some active learning time with a Concept MCQ: *Vector or Scalar?*

## Manuals

The manuals are available in the Copy Centre (at a cost of €14) and are required for Monday’s lecture.

## Test 1

The 15% Test 1 will be held in the Melbourne Hall, 16:00 Monday 14 October, Week 6. Ye all have lectures at 15:00 but I will request from your lecturers that ye be left go on time. There is a sample test in the notes.

## Diagnostic Test

If you haven’t already, you are invited to take the following ‘Diagnostic Test’:

This ‘Test’ does not go towards your grade, but allows me to give you some feedback on where you are in terms of material you have seen before that will be used in this module.

If you are a little worried about your maths this semester, perhaps after the Quick Test or in general, I would just like to remind you about the Academic Learning Centre. Most students received slips detailing areas of maths that they should brush up on. The timetable is here.

## Week 2

We continued working with the dot product and then introduced the cross product.

## Week 3

We will look at the applications of vectors to work and moments. We might begin Chapter 2: Matrices.
