MATH6055: Winter 2020, Week 4

October 22, 2020 in MATH6055 | Leave a comment

You are advised to to spend seven hours per week on MATH6055. With the first assessment on Wednesday, much of this time may be taken up revising Chapter 1.

The rest of you time should be spent however long it takes to watch the lectures, and then the rest of time should be spent emailing questions, doing exercises, and catch-up/revision.

30% Assessment 1

  • When? Wednesday Nov 4th, 6-7 pm.
  • Where? This exam will be made available as an assignment on Canvas.
  • Duration? You will be allotted 45 minutes for the exam and 15 minutes to upload pictures of your work via the canvas app, so 1 hour in total.
  • Topic? Sets and Relations (i.e. Chapter 1 up to but not including equivalence relations)
  • Marks? This exam will make up 30% of your total mark in this module.

If you have any questions in relation to the exam, please contact me.

Week 4

Lectures

Schedule about two hours to watch this hour and 20 minutes of lectures.

Exercises

Focus on Assessment 1

If you are revising for the first assessment I recommend:

  • If you submitted work on Canvas, read the feedback I gave you. If I recommend trying questions again, etc., do so.
  • If all done, go back on previous week’s questions that you did not complete.

You must understand that:

Any and all submitted work will receive feedback.

This includes work submitted late, or work emailed to me. It is easiest for me however if work is:

  • Submitted on Canvas to Reading Week Exercises
  • Properly labelled (page number and question)

You can (carefully) take photos of your work and submit to the Reading Week Exercises those images on Canvas before midnight Monday 2 November for feedback.

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.

Prepared for Assessment 1?

Try

  • p.56, Use your theorem to answer the following. Which of graphs 1-10 have a `route’ that uses every edge exactly once. Find the routes.
  • p.58, Q. 1-6
  • p.60, Q. 1
  • p.64, In Graphs 1-10, give the degree/valency of each vertex (this might already be done from the p.56 exercise)

Additional/Harder Exercises:

  • p.62, Implement the Task 3 A Algorithm to determine which of graphs 1-10 on the exercise sheet are connected.

Submit (after Thursday 5 November) before midnight Tuesday 10 November for feedback.

Week 5

In Week 5 we will complete Chapter 2: Network (Graph) Theory, and begin Chapter 3: Functions.

Zoom

Unfortunately when I sent the survey about Zoom, I had not yet “submitted” the Canvas feedback on the Week 1 exercises, and so students opinions might not have been fully informed… at the moment some respondents to the survey say they “need Zoom time”. If you want to have your say on this please fill in this survey (Links to an external site.)

This difficult topic will be considered by me again, perhaps after the Reading Break.

MATH7019: Winter 2020, Week 6 (2 – 8 November)

October 19, 2020 in MATH7019 | Leave a comment

This is being released early so that those who want to work on the Chapter 2 material and get ahead for Assignment 2, perhaps during Reading Week, may choose to do so. At the time of writing I have not decided when Assignment 2 will become available but all relevant lectures have been recorded here.

There is more than 7 hours learning tasks to get through here: realistically this learning will take place primarily over three weeks:

  • (For those getting ahead) Reading Week (26 October to 1 November)
  • Week 6
  • Week 7 (only a little bit of new material)

Again the target/recommendation is 7 hours per week (subject of course to your own time management around other modules, etc.).

Assignment 2

I had said that I would make Assignment 2, based on Chapter 2, available the morning after Assignment 1 is due. Instead I have made available, via the Week 6 announcement, the rest of the Chapter 2 material.

I will make Assignment 2 available sometime around the end of week 6, Monday of Week 7. It has a deadline the end of Week 8, Friday 20 November.

Week 6

Lectures

There is a lot of video here: two hours and 20 minutes… about three and a half hours of time… but the last video can be kept perhaps for Week 7 (9 – 15 November), and Week 7 is going to have very little video.

Exercises

There are a lot of exercises here. You might consider using the Reading Week to get a little ahead of this work.

You must understand that:

Any and all submitted work will receive feedback.

This includes work submitted late (i.e. Week 4 exercises submitted in Week 5), or work emailed to me. It is easiest for me however if work is:

  • Submitted on Canvas
  • Properly labelled (page number and question)
  • Ideally work that you know is correct (i.e. matches answer in the manual) not be submitted for feedback.

If you are completed the earlier Chapter 2 exercises, and/or feel confident watching the above video, you could look at:

  • p. 99, Q. 1-9 (mixture of simply supported and fixed ends)
  • p.107, Q.1-8 (mixture of simply supported, fixed ends, and cantilevers)
  • p.121, Q. 1-4 (maybe just use Euler’s Method at this time).

You can (carefully) take photos of your work and submit to the Week 6 Exercises.

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 7

There will be little new material in Week 7 as you will need time to focus on Chapter 2 with Assignment 2 due in Week 8.

We will begin Chapter 3 on Probability and Statistics. We will look in particular at Mutual Exclusivity and Independence.

Zoom

Unfortunately when I sent the survey about Zoom, I had not yet “submitted” the Canvas feedback on the Week 3 exercises, and so students opinions might not have been fully informed… at the moment one in three respondents to the survey say they “need Zoom time”, but some of them have not yet submitted to Canvas so… If you want to have your say on this please fill in this survey (Links to an external site.)

This difficult topic will be considered by me again, perhaps after the Reading Break.

MATH6055: Winter 2020, Week 3

October 15, 2020 in MATH6055 | Leave a comment

You are advised to to spend seven hours per week on MATH6055. This should comprise of however long it takes to watch the lectures, and then the rest of time should be spent emailing questions, doing exercises, and catch-up/revision.

30% Assessment 1 Week 4 (week of 2 November)

Provisionally the first assessment will take place in Week 4. It is provisionally based on everything up to (but not including) Section 1.4.2, but it might make sense (for the purposes of understanding best the earlier part of Section 1.4) to consider Section 1.4.2 part of the assessment.

More definitive information will be posted to Canvas in good time.

Zoom

In ordinary times, the majority of student learning takes place in tutorials where I am able to give one-to-one help to students. This is not possible at the moment so instead I am giving feedback on student exercises. This is very time consuming but I don’t believe it is possible for me to give you the teaching you need in a Zoom tutorial… but I might be wrong.

Please fill in this survey to tell me your opinion on how the tutorial aspect of my teaching is going.

It is a difficult balancing act. I could just do two Zoom hours per week but I simply don’t believe ye would get the one-to-one help in that way. I would be going way above and beyond my duties to do Zoom AND give weekly feedback on work but I have to hear what ye think.

If you would like to email me directly your thoughts on tutorial time (i.e. you would like some Zoom time and why), you can email me also (although the survey gives you a chance to do this).

Week 3

Lectures

Schedule about one and a half hours to watch this one hour of lectures.

Exercises

I recommend you spend five and a half hours this week on exercises (as there is so little lecture time). This means:

  • If you submitted work on Canvas, read the feedback I gave you. If I recommend trying questions again, etc., do so.
  • Once up on your feedback, try the recommended questions (below).
  • If all done, go back on previous week’s questions that you did not complete.

You must understand that:

Any and all submitted work will receive feedback.

This includes work submitted late (i.e. Week 2 exercises submitted in Week 3), or work emailed to me. It is easiest for me however if work is:

  • Submitted on Canvas
  • Properly labelled (page number and question)
  • Ideally work that you know is correct (i.e. matches answer in the manual) not be submitted for feedback.

Do/attempt:

  • p. 49, Q. 1
  • p. 50, Q. 2-7
  • p. 51, Q. 8-9

Additional/Harder Exercises:

  • For each of the relations on p.44: Is the relation transitive? Justify your answer.

You can (carefully) take photos of your work and submit to the Week 3 Exercises those images on Canvas before midnight Tuesday 27 October for feedback.

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.

Reading Break

It is currently my understanding that ye will have a Reading Break 26 October to 1 November. You will use this time to complete your Chapter 1 learning (especially doing exercises).

Week 4

In Week 4 we will start Chapter 2: Network (Graph) Theory.

MATH7019: Winter 2020, Week 5

October 15, 2020 in MATH7019 | Leave a comment

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 emailing questions, doing exercises, completing assignments, and catch-up/revision.

30% Assignment 1

With a deadline of 23.59, Friday of Week 5, 23 October for Assignment 1, you must consider time management. Perhaps it might be a good idea to watch lectures, and then spend the rest of your MATH7019 time on Assignment 1.

In the context of this assignment I use the term Originality of Presentation and this video explains what this means.

As the video also explains two files must be submitted:

  • a single *.pdf report consisting of your written answers as well as appropriate Excel content. Ideally the Excel work for Problem A near the written work for Problem A, etc.
  • an Excel file

Ordinarily I assign late work a mark of zero. As explained in the video my strong recommendation is that you submit what you have done on time. Submitting late is only going to cause backlogs in your other modules.

MATH7019: Winter 2020, Week 4

September 16, 2020 in MATH7019 | Leave a comment

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.

Academic Learning Centre

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 2

You are advised to to spend seven hours per week on MATH6055. 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. At the time of writing, the mechanism for submitting work is not yet set up.

Lecture

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

Here is the first tranch of notes if you have not purchased nor printed off a manual

Exercises

I recommend spending four hours on this week’s exercises.

I do not at the time of writing have the mechanism in place for submitting work.

You can (carefully) take photos of your work. If possible, convert the images to 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.

Ordinarily I would encourage you to ask questions via email at any time but at present this mechanism is not in place.

Do/attempt:

  • p. 32, Q. 10-11
  • p. 33, Q. 12-14
  • p. 38, Q. 1-5
  • p. 39, Q. 6
  • p. 43, Q. 1-2

Additional/Harder Exercises:

  • p.34, Q. 26
  • p. 39, Q. 7-8
  • p. 43, Q. 3-6

Week 3

In Week 3 we will finish Chapter 1 by looking more at relations and their properties. We will start our study of Chapter 2: Functions. A function is a special type of relation.

Academic Learning Centre

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

At the time of writing, the assessment schedule has not been finalised, but we are considering two 50% tests.

Paternity Leave

I will be on paternity leave until Monday 12 October. My colleague Dr Mark Hartnett (mark.hartnett@cit.ie) will answer any email queries that you have.

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:

image.png

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 MATH6055 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 €13. This seems like a lot of money for a manual but with all the materials (including exercises, summaries, etc) it comes to 165 pages and provides a comprehensive resource for this module.
  2. Print off the manual at home or somewhere else. Click here to find a copy.
  3. I am going to scan and email the completed slides. You can keep these somewhere for your notes. You could print these or keep digital copies. Here is the first tranch of notes.

Week 1

You are advised to to spend seven hours per week on MATH6055. 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.

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.

  • 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.

  • p.34, Q. 1-4
  • p.37, Autumn 2015

Additional (Harder) Exercises:

  • 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.

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).
