You are currently browsing the category archive for the ‘MATH6040 – Day’ category.

The manuals are available in the Copy Centre (at a cost of €15). These are needed to participate properly in class.

Test 1

The test will be the Tuesday evening, 11 October, of Week 5. See Canvas (MATH6040 —> Assignments) for further details.

Week 3

We finished Chapter 1, and the material for Test 1, by talking at the applications of vectors to work and moments. We also started Chapter 2, on Matrices.

Week 4

We will continue working on matrices. We will look at Matrix Inverses — “dividing” for Matrices. This will allow us to solve matrix equations. We also looked at determinants.

Some deeper discussion here: Why do we multiply matrices like we do?, Why can’t I divide by zero?

Tutorials

The most important thing in your MATH6040 world is to attend tutorials regularly.

So far the free choice to attend any of the following is working OK.

  • Wednesday 12 pm in B180 (the official SEE2 tutorial slot),
  • Wednesday 3 pm in B260 (the official BioEng2A slot)
  • Friday 1 pm in B260 (the official BioEng2B + “SEE2 excess” slot)

See here for more.

Test 2

Test 2 is provisionally booked for the Tuesday of Week 12:

06/12/202218.00-19.00MATH6040Technological Maths 20155A – C

However, this is too late, it should be Week 11, but the Melbourn Hall is provisionally unavailable in Week 11.

When the timetable system is back up and running again I will try and book a large IT room for this test, and I will also try and wing us into the Melbourn for 29 November.

So Test 2 is 99% going to be Tuesday 29 November but just in case I have booked the Melbourn for 6 December. This will be finalised by Week 9.

The manuals are available in the Copy Centre (at a cost of €15). In my opinion the sooner ye purchase them the better, but ye will certainly need them by Week 4.

Tutorials

The official line is that BioEng2A have their tutorial, BioEng2B have their tutorial, and SEE2 have a tutorial, but it is too big, so “The SEE2 excess go to (the) BioEng2B (tutorial)”. I think we have a better set up by allowing all students attend whatever tutorial they want:

  • Wednesday 12 pm in B180 (the official SEE2 tutorial slot),
  • Wednesday 3 pm in B260 (the official BioEng2A slot)
  • Friday 1 pm in B260 (the official BioEng2B + “SEE2 excess” slot)

I think SEE2 students can make all three and BioEng2 students can make two every week, and three some weeks. A number of students have asked can they attend more than one tutorial a week. As long as I can keep getting around to everyone to give one-to-one teaching I am happy with students attending more than one tutorial.

If it happens that the above plan doesn’t work, and some tutorial(s) is too big, I will have to think again.

The most important thing in your MATH6040 world is to attend tutorials regularly.

Test 1

The test will be the Tuesday evening, 11 October, of Week 5. See Canvas (MATH6040 —> Assignments) for further details.

Week 2

In Week 2 we spoke about vector products: the dot product and the vector product.

Week 3

In Week 3 we will Chapter 1, and the material for Test 1, by talking at the applications of vectors to work and moments

Timetable Issues

For this week only, the SEE2 tutorial at 3 pm on Thursday will not go ahead. Instead the SEE2 tutorial will be held in A272 at 12 pm on Wednesday.

Please keep an eye on your email on Monday. If the AV situation is not sorted in A272 by then I will be trying to arrange alternative rooms (which has its own risks).

Week 1

We began our study of Chapter 1, Vector Algebra by studying the difference between a scalar (single number) and a vector (list of numbers). We looked at how to both visualise vectors and describe them algebraically. We learned how to find the magnitude  and direction of a vector, add them and scalar multiply them. We spoke about displacement vectors.

Week 2

In Week 2 we will talk about vector products: the dot product and the vector product.

Test 1

The test will probably be the Tuesday evening, 11 October, of Week 5. Official notice will be given in Week 3. There is a sample test in the notes.

Mathematics Exam Advice

  • 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:

  1. have I answered the question that was asked?
  2. does my answer make sense?
  3. check your answer (e.g. differentiate/antidifferentiate an antiderivative/derivative, substitute your solution into equations, check your answer against a rough estimate, or what a picture is telling you, etc)

Test 2

On Chapter 3, on at 5 pm (not 4 pm) Monday 25 November, Week 11 in Melbourne Hall. You will have one full hour.

The BioEng2B tutorial will take place from 4 pm sharp to 4.45 pm in B263 on that day.

Chapter 3: Differentiation is going to be examined. A Summary of Differentiation (p.147-8): you will want to know this stuff very well. You will be given a copy of these tables

There is a sample test on p. 149 of the notes.

I strongly advise you that attending tutorials alone will not be sufficient preparation for this test and you will have to devote extra time outside classes to study aka do exercises.

Between tutorials and private study you really should aim to have completed as least the following:

  • P. 113, Q. 1-6 (not 5c or 6iii)
  • P. 119, Q. 1-4
  • P. 127, Q. 1-4
  • P. 138, Q. 1-3
  • P. 146, Q. 1-4
  • The Sample Test

There are more questions in most of these exercises.

If you are having any problem, take a photo of your work and email me your question.

Week 10

We started Chapter 4 on (Further) Integration with a revision of antidifferentiation, and had a look at Integration by Parts. We used implicit differentiation to differentiate inverse sine.

Week 11

We have our test on Monday, then we will look at completing the square, and work on Tuesday and Thursday.

Week 12

We will look at centroids of laminas and centres of gravity of solids of revolution. Any spare lecture time will be given over to tutorial time.

Week 9

We looked at partial differentiation and its applications to differentials and error analysis.

I had hoped to do a Concept MCQ for Chapter 3 but we kind of ran out of time… I would ask ye to complete this (on your own) before Monday.

Week 10

We will start Chapter 4 on (Further) Integration. A good revision of integration/antidifferentiation may be found here, but this material will be gone through in Monday’s lecture..

Test 1

Results and Marking Scheme have been emailed to you.

Test 2

On Chapter 3, is planned for 5 pm (not 4 pm) Monday 25 NovemberPlease contact me if this poses a problem for you.

Outlook

For most students, Chapters 1 and 2 are easier and you will want to do well on them. Things are going to get a little harder for the rest of the semester and you will need to attend class regularly and prepare well for Test 2.

You have already been recommended to use your Reading Week:

If you plan on doing some work on MATH6040 over the Reading Week, may I recommend looking at Chapter 2 exercises:

P. 95, Q. 1 (find b only), Q. 2-4
P. 85, Q. 1
P. 80, Q. 1-4
P. 84, Q. 1-2
P. 64, Q. 1-4 (remember BEMDAS — AD^T = A(D^T) not = (AD)^T)
If you are happy with these look at the differentiation revision: p.103, Q.1-2
You can email me at any time if you have any questions.

Week 7

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

Here are two videos if you missed this material:

We mentioned briefly the Reuleaux Triangle and it’s use in the “Harry Watt Square Drill Bit”. See here for an animation of how this works.

Week 8

We will finish looking at Related Rates and then look at Implicit Differentiation. If you are interested in a very “mathsy” approach to curves you can look at this.

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:
