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.

Manuals

The manuals are available in the Copy Centre. Please purchase ASAP. More information has been sent via email.

Telegram App

I am exploring the possibility of setting up a classroom group chat that would have the functionality of WhatsApp without having your phone number made public.

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

FAO: Erasmus Students — Calculators

The Student Resources tab above contains some information about calculators.

Here is a list of some allowed and not allowed calculators.

If you have to purchase a calculator, my recommendation is that you purchase something like a Casio fx-83GT PLUS. This might be available in the CIT shop.

Tutorials

Tutorials, which are absolutely vital, start next week. There may be a split but this might not occur until Week 3.

Week 1

In week one we had one and a half classes. One half class was given over to a general overview of MATH7019 and we spent about an hour introducing the topic of Curve Fitting including Lagrange Interpolation.

Week 2

We will start talking about Least Squares curve fitting.

I would urge anyone having any problems with material that isn’t being addressed in the tutorials to use the Academic Learning Centre. If you are a little worried about your maths this semester, perhaps after the Quick Test or in general, you need to be aware of this resource. The timetable should be up some time next week.

You will get best results if you come to the helpers there with specific questions. Next week, some students will receive slips detailing areas of maths that they should brush up on.

Assessment 1

Assessment 1 will have a hand-in date the Friday of Week 5, 11 October. The Assignment is in the manual but I must also send on your personal data sets next week.

Study

Please feel free to ask me questions about the exercises via email or even better on this webpage — especially those of us who struggled in the test.

Talk delivered to the Conversations on Teaching and Learning Winter Programme 2018/19, organised by the Teaching & Learning Unit in CIT (click link for slides):

Contexts and Concepts: A Case Study of Mathematics Assessment for Civil & Environmental Engineering

• 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.

Assessment 2

I am working my way through these. I promise you your final CA results before Monday morning.

Week 12

We finished off Chapter 4 by looking at Error Analysis, including rounding error. We had a tutorial for a lecture on Wednesday, and Thursday might allow some tutorial time.

Week 13

We will go through last year’s exam on the board and then I will answer your questions if there are any. If there are none I will help one-to-one. Usual class times and locations.

We will also have tutorials on Friday 14 December at the usual times and venue. If there aren’t too many students present (max 18), you can attend both tutorials.

Past exam papers (Winter and Autumn) may be found here.

Assessment 2

I have started correcting these: I won’t make any promises but will do my utmost to have them to you as soon as possible, certainly sooner than the end of next week.

Week 11

We looked at more general Taylor Series: not just near $a=0$ — and also for functions of several variables. Here are some reasons why an engineer might be interested in Taylor Series of functions of several variables.

Week 12

We will finish off Chapter 4 by looking at Error Analysis, including rounding error. We should be able to hold an additional tutorial or two.

Week 13

We will go through last year’s exam on the board and then I will answer your questions if there are any. If there are none I will help one-to-one. Usual class times and locations.

We will also have tutorials on Friday 14 December at the usual times and venue.

Assessment 2

Assessment 2 is on p.136.

• The hand in deadline is 16:00 this Monday 26 November 2018.
• Hand it at tutorial today — or 13:00 on Monday. Otherwise drop it into my office, A283. I should be here Monday 11:00-13:00, 14:00-15:00. Outside these times there should be someone in A283 who can let you in and leave your assignment on my desk.
• Hand in whatever you have done by the deadline: work handed in late will be assigned a mark of zero.
• Email me your Excel work.
• Print off a hard copy of your excel and submit this with any other written work.
• Further instructions in the manual.

Week 10

We began Chapter 4 with a Revision of Differentiation, and on Wednesday you had a tutorial to get up to grips with calculating derivatives.

We went on to look at at Maclaurin Series.

Week 11

We will look at more general Taylor Series: not just near $a=0$ — and also for functions of several variables.

Assessment 2

Assessment 2 is on p.136. It has a hand-in time of 16:00 Monday 26 November.

As suggested in class, I would advise you to — if possible — complete this assignment early if you can, freeing up time in your tutorial to get work done on Chapter 3: Probability & Statistics.

Week 9

We completed Chapter 3 by looking at Sampling and Hypothesis Testing. We had a tutorial for a lecture on Wednesday.

Week 10

We will begin Chapter 4 with a Revision of Differentiation and go on to look at then at Maclaurin Series and Taylor Series. We might hold an extra tutorial for a lecture.

Assessment 1 – Results

I will have the assignments with me tomorrow if you want to see your work.

Assessment 2

Week 8

We looked at the Poisson distribution, the Normal distribution, and started discussing Sampling.

Week 9

We will complete Chapter 3 by looking at Sampling and Hypothesis Testing. We may have an extra tutorial during one of the lectures.

Assessment 1 – Results

I will have the assignments with me tomorrow and next Friday if you want to see your work.

Assessment 2

Assessment 2 is on p.136. It has a hand-in time of 16:00 Monday 26 November.

Week 7

We finished looking at Chapter 2 by looking at the Three Term Taylor Method for approximating solutions of ordinary differential equations.

We started Chapter 3 (Probability and Statistics) by looking at some general concepts in probability and then we looked at random variables with a binomial distribution.

Week 8

We will look at the Poisson distribution and perhaps the Normal distribution.

Assessment 1 – Results

I am starting corrections today and will get the results to you as soon as I can. I cannot give an accurate day at this stage: it could be Monday but just as easily could be a few days after this – I can’t make any promises.

Assessment 2

Assessment 2 is on p.136. It has a hand-in date of Monday 26 November and we have already covered everything that will be asked and so you have over five weeks to complete the assignment.

MicDrop Project

On Monday you will be sent a 15 minute survey that you will take on a mobile internet device — such as your mobile phone — during Monday’s lecture.

This survey is part of a larger project the Mathematics Department is undertaking —  Mathematics in Context: Developing Relevancy-Orientated Problems — in an effort to improve our teaching.

If you do not have an internet ready device you may leave class early.

Maths Classes will be going full steam ahead on Monday 22 October as well as Wednesday, Thursday, Friday 1, 2, 3 November. I will call the next two weeks by Week 7.

Week 6

In Week 6 we finished looking at cantilvers and then summarised what we learnt about beams. We had one lecture as a tutorial but then looked at numerical approximations to solutions of differential equations that we cannot solve exactly.

After the storm last year I recorded some examples. If you missed some classes this week you could do worse than watch this cantilever example and this summary of beams to catch up

Week 7

In Week 7 we will look at the Three Term Taylor Method and begin Chapter 3 on Probability and Statistics.

Assessment 1

If you haven’t started this you seriously need to get cracking.
