## Week 4

You are advised to to spend seven hours per week on MATH7019. This should comprise of however long it takes to watch the lectures, and then the rest of time should be spent doing exercises, emailing questions, and submitting work. Also catching up on material we have already covered, and doing exercises. At the time of writing, tutorials consist of you emailing questions and getting feedback on submitted work, but this is subject to change.

### Lecture

Schedule about two and half hours to watch these 104 minutes of lectures. I recommend about 50% extra time as you will want to pause/rewind.

### Exercises

You need to schedule about four and half hours to work on this week’s exercises.

Do not hesitate to contact me with questions at any time. My usual modus operandi is to answer all queries in the morning.

• p. 72 (instructions) for p. 73, Q. 1-5
• p. 89, Q. 1

You can (carefully) take photos of your work and submit to the Week 4 Exercises those images on Canvas before midnight Sunday 18 October. The intention would be that after 09:00 Monday 19 October someone (I am going on two weeks paternity leave at some stage) will download all student work and reply with feedback.

If possible, submit the images as a single pdf file. To do this, select all the images in a folder, right-click and press print. It will say something like How do you want to print your pictures? Press (Microsoft?) Print to PDF. If possible choose an orientation that has all the images in portrait.

## Week 5

We will then look at more examples of simply supported beams before moving onto fixed-end beams.

I would urge anyone having any problems with material that isn’t being addressed in the tutorial communication to use the Academic Learning Centre. If you are a little worried about your maths this semester you need to be aware of this resource. You will get best results if you come to the helpers there ith specific questions.

## Assessment 1

Assessment 1 has a provisional hand-in of the end of Week 4, start of Week 5. Once the class list is established I can send on the student-number-personalised assessment.

## Week 3

You are advised to to spend seven hours per week on MATH7019. This should comprise of however long is recommended to watch the lectures, and then the rest of time should be spent doing exercises, emailing questions, and submitting work. At the time of writing, tutorials consist of you emailing questions and getting feedback on submitted work, but this is subject to change.

### Chapter 1 Lectures

Schedule about an hour and a quarter to watch these 51 minutes of lectures. I recommend about 50% extra time as you will want to pause/rewind.

Here are Chapter 1 slides if you have not purchased or printed off the manual.

### Chapter 1 Exercises

You need to schedule about two and a quarter hours to work on these exercises.

• p.41, linearise.
• p.49, Q.1-7.

### Chapter 2 Lectures

Schedule about an hour and a quarter to watch these 54 minutes of lectures. I recommend about 50% extra time as you will want to pause/rewind.

### Chapter 2 Exercises

You need to schedule about two and a quarter hours to work on these exercises.

• p. 59, Q. 1-2.
• p.65, Q.1-3.

### Information for Exercises

Do not hesitate to contact me with questions at any time. My usual modus operandi is to answer all queries in the morning but sometimes I may respond sooner. I am not sure exactly what will happen with these questions while I am on paternity leave… hopefully someone will take these questions for you.

You can (carefully) take photos of your work and submit to the Week 3 Exercises those images on Canvas before midnight Sunday 11 October. The intention would be that after 09:00 Monday 12 October someone (I am going on two weeks paternity leave at some stage) will download all student work and reply with feedback.

If possible, submit the images as a single pdf file. To do this, select all the images in a folder, right-click and press print. It will say something like How do you want to print your pictures? Press (Microsoft?) Print to PDF. If possible choose an orientation that has all the images in portrait.

## Week 4

We will plough into Chapter 2, looking at simply supported beams.

I would urge anyone having any problems with material that isn’t being addressed in the tutorial communication to use the Academic Learning Centre. If you are a little worried about your maths this semester you need to be aware of this resource. You will get best results if you come to the helpers there ith specific questions.

At the time of writing, tutorials consist of you emailing questions and getting feedback on submitted work, but this is subject to change.

### Lecture

Schedule about three hours to watch these 126 minutes of lectures. I recommend about 50% extra time as you will want to pause/rewind.

Here are Chapter 1 slides if you have not purchased or printed off the manual.

### Exercises

You need to schedule about four hours to work on this week’s exercises.

I am not sure exactly what will happen with these questions while I am on paternity leave… hopefully someone will take these questions for you.

• p.34, Q. 1-4
• p.37, Autumn 2015

• p.22, show that $\displaystyle \frac{\partial^2S}{\partial a^2}$ and $\displaystyle \frac{\partial^2S}{\partial b^2}$ are both positive.
• p.26, repeat the page 22 analysis for $Z=aX+bY+c$:

$\displaystyle S(a,b,c)=\sum_{i=1}^N(Z_i-aX_i-bY_i-c)^2$

Partially differentiate this with respect to $a$, $b$, $c$, solve equal to zero, to find the equations in the middle of p.26.

You can (carefully) take photos of your work and submit to the Week 2 Exercises those images on Canvas before midnight Sunday 4 October. The intention would be that after 09:00 Monday 5 October someone (I am going on two weeks paternity leave at some stage) will download all student work and reply with feedback.

If possible, submit the images as a single pdf file. To do this, select all the images in a folder, right-click and press print. It will say something like How do you want to print your pictures? Press (Microsoft?) Print to PDF. If possible choose an orientation that has all the images in portrait.

## Week 3

We will start looking at non-linear models.

I would urge anyone having any problems with material that isn’t being addressed in the tutorial communication to use the Academic Learning Centre. If you are a little worried about your maths this semester you need to be aware of this resource. You will get best results if you come to the helpers there ith specific questions.

## Manuals

The lectures are being delivered via pre-recorded lectures. As you will see, the lectures use a manual that contain all the lecture material, via gaps that are filled in during lectures, and exercises. I tend to use a number of colours during lectures, and pencil, so you might want to consider ordering some of these:

In a sliding scale from best to worst, in my opinion, here are your options for using this manual. There are other options but I cannot recommend them. If you do option one you have all your notes in one place and can follow the lectures as if you were in the classroom.

1. Email copy.centre@cit.ie and tell them you want to order a bound copy of MATH7019 Manual Winter 2020. The manuals can be collected from Reprographics beside the Student Centre. Note that this is a cash-free area so you will need to put the appropriate amount of funds on your student card. At the time of writing I do not know the cost but it will be of the order of €15. This seems like a lot of money for a manual but with all the materials (including worked examples, summaries, etc) it comes to about 187 pages and provides a comprehensive resource for this module.
2. Print off the manual at home or somewhere else. Click here here to find a copy.
3. I am going to scan and email the completely slides. You can keep these somewhere for your notes. You could print these or keep digital copies. Here is Chapter 1.

## Week 1

You are advised to to spend seven hours per week on MATH7019. This should comprise of however long is recommended to watch the lectures, and then the rest of time should be spent doing exercises, emailing questions, and submitting work. At the time of writing, tutorials consist of you emailing questions and getting feedback on submitted work, but this is subject to change.

There is probably less than two and half hours here for Week 1: this might be nice to ease yourself back into things, but if you are hungry for more material feel free to jump into Week 2 (see Canvas announcements).

• The first piece of advice is to read questions carefully. Don’t glance at a question and go off writing: take a moment to understand what you have been asked to do.
• Don’t use tippex; instead draw a simple line(s) through work that you think is incorrect.
• For equations, check your solution by substituting your solution into the original equation. If your answer is wrong and you know it is wrong: write that on your script.

If you do have time at the end of the exam, go through each of your answers and ask yourself:

2. does my answer make sense? If no, say so, and then try and fix your solution.
3. check your answer (e.g. for a fitted curve or beam function, input values and see do they make sense; substitute your solution into equations; check your answer against a rough estimate; or what a picture is telling you; etc). If your answer is wrong, say so, and then try and fix your solution.

## Student Feedback

You are invited to give your feedback on my teaching and this module here.

## Tutorial Split

I am not sure what is going on with Leonard’s classes but I will be present this Friday, tomorrow 6 December for tutorials in A243L (11:00) and A213B (12:00).

## Week 12

On Monday we finished off Chapter 4 by looking at Error Analysis. Better exercises than the book here (including corrections to the sheet handed out in class). We then had over two and a half hours of tutorial time for lectures, and another tutorial on Friday.

## Assessment 2 — Results

These have been sent to you. Comments to follow.

## Week 11

We had a tutorial dedicated to differentiation on Monday.

We tried to look at a Probability and Statistics Word Cloud on Wednesday. It was a disaster as my computer froze… anyway:

My answer: when $A$ and $B$ are independent.

A difficult one. My answer: Every probability/area under a bell curve can be calculated by transforming the area to a $z$ curve, and calculating the area ‘there’.

My answer: To infer things about the population, e.g. the population mean.

My answer: An interval that we believe the population mean is in (with a certain confidence).

On Wednesday and Thursday we had a look at more general Taylor Series: not just near $a=0$, before doing a revision of partial differentiation, and linking at error analysis.

## Tutorial Split

See my email of 12 November regarding the Friday tutorial split for the rest of the semester.

Tomorrow we go back to the normal room of A213B for the 12:00 tutorial.

## Assessment 2 — Corrections

Hopefully I can get these to ye within the week. I have some ‘man flu’ at the moment but hopefully that goes away.

## Week 10

We had an extra tutorial on Monday. Most people concentrated on the Sample Question 3s on Probability and Statistics.

We finished off Chapter 3 — and spoke about the Bad and Good and Bad News — before we began Chapter 4 with a Revision of Differentiation and had a look at Maclaurin Series.

Oh: one thing — I never told ye what a p-value was (Sample Paper I Q. 3 (c) B ii.). It is the same as the level of significance, the probability of making a Type I Error… the answer is 5%.

## Week 11

We will have a tutorial dedicated to differentiation on Monday.

We might look at a Probability and Statistics Concept MCQ on Wednesday.

On Wednesday and Thursday we will have a quick look at more general Taylor Series: not just near $a=0$, before doing a revision of partial differentiation.

## Tutorial Split

See my email of 12 November regarding the Friday tutorial split for the rest of the semester.

## Assessment 2

Three things must be submitted:

• a soft, digital, copy of your Excel file MATH7019A2 – Your Name
• a hard copy of your Excel file MATH7019A2 – Your Name

The soft copy is to be be submitted on CANVAS.

Combine the second two elements into one report. Ideally the Excel work for Problem A near the written work for Problem A, etc. If this isn’t easy, maybe just put all the written work at the front, and all the Excel work at the back.

The assignment can be handed up in any class before Monday 18 November (inclusive). I expect most to hand it up on Monday:

• Monday, 18 November 13:00 in B228,

Otherwise drop the assessment to my office A283. I will be here Monday 18 November, until 16:00 sharp (which is the deadline).

Work assigned late will be awarded a mark of zero. Hand up what you have on time.

## Week 9

We had an extra tutorial on Monday.

We continued to slowly work our way through Chapter 3 by looking at Sampling and Hypothesis Testing.

## Week 10

We will have an extra tutorial on Monday.

We will finish off Chapter 3 — and talk about the Good and Bad News — before we begin Chapter 4 with a Revision of Differentiation and go on to look at Maclaurin Series and Taylor Series.

## Assessment 2

Assessment 2 is on p.137. The relevant Excel files have been emailed to you. It has a hand in date/time of 16:00 Monday 18 November, Week 10.

Start ASAP.

## Week 8

We did more work on Chapter 3; we looked at the Normal distribution, and we started discussing Sampling.

## Week 9

We will continue to slowly work our way through Chapter 3 by looking at Sampling and Hypothesis Testing.

We will have an extra tutorial on Monday.

There will also be a new arrangement with tutorials next week — watch your email.

## Assessment 2

Assessment 2 is on p.137. The relevant Excel files have been emailed to you. It has a hand in date/time of 16:00 Monday 18 November, Week 10, and you can already do all the questions.

Start as soon as reasonable: perhaps during this Reading Week.

## Week 7

We had a tutorial on Monday on Static Beam Equations. On Wednesday we looked at an MCQ on Static Beam Equations.

Then we looked at the Three Term Taylor Method and began Chapter 3 on Probability and Statistics. We looked in particular emphasis on Mutual Exclusivity and Independence.

Our Wednesday lecture was only 30 minutes long.

## Week 8

We will do more work on Chapter 3; perhaps we will start looking at the Normal distribution. We will not have a tutorial this Monday.
