COMP1B-Y tutorial in Week 8

In Week 8, Thursday March 16, the COMP1B-Y tutorial will be held at 10:00 in A243L rather than 11:00 in C128.

Week 7

We started talking about argument and inference. We had additional tutorial time again on Tuesday and our 20% on Wednesday evening.

Week 8

Argument and inference is difficult: and we will be spending all week trying to get a better handle on it.

Week 9

We will have Quiz 3 20 March at 3 pm in the usual lecture venue. It will be based on argument and inference.

DME2B Lab venue change and DME2C Lab Week 8

With the bank holiday, there will be no Friday DME2C Lab in Week 8. Instead I have scheduled:

• Monday 13 March, IT1.2, 09:00-11:00

This will be Lab 6. We will be skipping Lab 5. It might be a little tricky in that we might not have loads of the theory done. This cannot be helped.

In any case, if students cannot make this important lab they can try and do the lab remotely using the Lab vidoes on Canvas.

DME2B’s lab is going to be in F2.11 for the rest of the semester. This is to facilitate another class whose software is in A285 but not F2.11.

Week 7

We (started) looking at boundary value problems (in particular the Shooting Method).

On Wednesday we had our first written assessment.

In VBA we had our first VBA Assessment

Week 8

We will finish looking at boundary value problems (in particular Goal Seek) and maybe look at partial differential equations by looking at Laplace’s Equation.

In VBA we will have Lab 6. We will skip Lab 5.

Week 8

Finish Section 1.10

Lab 6 (we will skip Lab 5)

Week 9

Section 2.1

Lab 7

Week 10

Section 2.2

Lab 8 (material examinable in final assessment)

Week 11

Finish Section 2.2 and then tutorial time

VBA Assessment 2 in the lab slots

Week 12

Tutorial-like class in the Tuesday lecture. If DME2C are not able to attend any of the Tuesday labs, there will be no labs.

Assessment

See Canvas for the assessment schedule. There will be more information on assessments the Friday of the week two before the assessment week (i.e. info on Friday of Week 4 about the Week 6 assessment).

Timetable Issues

The Monday class has now been switched to Tuesday 2 pm in A243L.

The week after, we were due to to have a double tutorial, 12:00 sharp to 13:40 on Monday 13 March in A207. Then on Thursday we will not have a double class, but instead just have a 09:05-09:55 class. With the timetable change, and how lectures are progressing, we will just cancel Thursday 16 March 10 am.

15% Assignment 1

This has a revised deadline. Please see Canvas.

Week 6

On Tuesday (Monday class was moved) we had some tutorial time on Chapter 2.

On Wednesday we finished Chapter 2 and then looked at The Engineer’s Transform” — the Laplace Transform.

On Thursday, in a double class, we did a survey, and then started looking at partial fractions.

Things are more serious now as we start Chapter 3. We must work hard on this material:

1. because without doing so you could be very, very lost on 15% Assignment 2 (and 35% exam question), and
2. because if you are going into Level 8 Structural Engineering it will be assumed that you are competent with the Chapter 3 material

Week 7

On Monday (or perhaps Tuesday, pending timetable changes), we will have a final Chapter 2 tutorial.

Then the rest of the class will be given over to partial fractions and then the inverse Laplace transform.

Week 8

On Monday, we are due to have a double tutorial.

The rest of the week will be focused on finishing Chapter 3.

Week 9

This should be a bumper week of Chapter 3 tutorials if we have finished Chapter 3. It will be in this week that we catch up as we will skip Section 3.6.

Week 10

This will be a bumper week of tutorials so that you are in great nick to do Assignment 2 over Easter.

Week 11

We will work on double integration and when we finish that section we will have tutorials.

Assignment 2

Assignment 2 will have a hand-in time and date of 11:00 20 April. Assignment 2 is in the manual. Once we get someway into the examples on p.126 you should be able to make a start.

Week 12

We will work on triple integration. When finished we will have tutorial time on that topic.

Week 13, Review Week

We will go through an exam paper, answer questions, and have tutorial time as appropriate. The Monday is a bank holiday. This may or may not affect us.

In VBA we worked on Lab 4.

Week 7

We will start looking at boundary value problems (in particular the Shooting Method and Goal Seek) on Tuesday, and have Written Assessment 1 on Wednesday.

The Lab will be given over to the VBA Assessment.

20% Test in Week 7

There will be a 20% Test based on the material we covered in the first five weeks.

• Wednesday March 8th, 6-7pm, Melbourn Hall

For those enrolled on Maths Online, there are some videos here. Please let me know if this link does not work.

Week 6

On Monday we continued working on logic, doing more examples with logical equivalence. Either simplifying compound propositions, or showing that two compound propositions are logically equivalent. On Tuesday, we had a tutorial-lecture, looking at p.41. I also gave out the following table. On Wednesday we started talking about argument and inference.

In tutorials you worked on p.41 also.

Week 7

We will do more argument and inference. We will have additional tutorial time again on Tuesday.

COMP1B-Y tutorial in Week 8

In Week 8, Thursday March 16, the COMP1B-Y tutorial will be held at 10:00 in A243L rather than 11:00 in C128.

This has a revised deadline. Please see Canvas.

Week 5

On Monday we had very poor attendance (something we are trying to do something about) so the students present were invited to start work on Assessment 1.

On Wednesday and Thursday we drove further into Chapter 2, the method of undetermined coefficients for linear differential equations. We more-or-less have it all covered, but we need to see more examples.

Week 6

We will have tutorial time on Chapter 2 on Monday, and probably only one more Chapter 2 tutorial slot.

Then we will finish Chapter 2.

Things will get more serious now as we start Chapter 3. We must work hard on this material:

1. because without doing so you could be very, very lost on 15% Assignment 2 (and 35% exam question), and
2. because if you are going into Level 8 Structural Engineering it will be assumed that you are competent with the Chapter 3 material

Chapter 3 is about “The Engineer’s Transform” — the Laplace Transform. We will look at the first shift theorem, and how the Laplace Transform interacts with differentiation. We will start looking at partial fractions.

The second 2.5% quiz will be 15.05 pm (SHARP), Monday 27 February in B217. The quiz will be projected on the screen, and you will write your answers on a sheet I hand out at the start of class.

The quiz will be bases on sections 2.1, 2.2, and 2.3. You will need to know what a proposition is, you will need to understand the basic logical connectives (but not the material implication nor biconditional). You will also need to be able to complete and construct truth tables.

20% Test in Week 7

There will be a 20% Test based on the material we covered in the first five weeks.

• Wednesday March 8th, 6-7pm, Melbourn Hall

Watch this space (or Canvas) for more information.

Week 5

We continued working on logic, defining the logical equivalence of compound propositions and by:

• when is a tautology, we say that and are logically equivalent, and we write

We had a whole collection of “laws of logic”, which are common logical equivalencies. Your idiot lecturer has some typos here that we will correct on Monday (after Quiz 2). Like with the laws of sets, we can use these laws of logic to simplify compound propositions. Another question type is to show that two compound propositions are logically equivalent, . We can use these laws of logic, or show using truth tables that is a tautology.

On Tuesday, we had a tutorial-lecture, looking at p.36. In tutorials you worked on exercises (p.36, 41).

Week 6

We will do more simplifying using laws of logic (after Quiz 2). We will have more tutorial-lecture time on Tuesday. Then we should start argument and inference on Wednesday.

COMP1B-Y tutorial in Week 8

Note that Written Assessment 1 has been pushed back one week. This is to help ye, in the sense that ye would otherwise have four assessments next week. Because the VBA Assessment is based on Heun’s Method, there is a good overlap between the material and I am happy enough this isn’t a MATH7016 overload.

20% Written Assessment 1, 8 March

Please see Canvas for more information.

20% VBA Assessment 1, 7-10 March

Please see Canvas for more information.

Week 5

We finished talking about Heun’s Method. Then we quickly spoke about the Three Term Taylor Method. Then we calculated some Maclaurin series before starting to talk about second order differential equations and how to attack them numerically.

In VBA we worked on Heun’s Method.

Week 6

We will work hard on second order differential equations. We will only briefly gloss over Runge-Kutta methods, focussing more on the case studies rather than the actual methods.

In VBA we will work on Lab 4.

Week 7

We will start looking at boundary value problems (in particular the Shooting Method and Goal Seek) on Tuesday, and have Written Assessment 1 on Wednesday.

The Lab will be given over to the VBA Assessment.

DME2C Lab 13 March, Week 8

With the bank holiday, there will be no Friday DME2C Lab in Week 8. Instead:

• Monday 13 March, IT1.2, 09:00-11:00

This will be Lab 6. We will be skipping Lab 5. If students cannot make this important lab they can try and do the lab remotely using the Lab vidoes on Canvas.

15% Assignment 1

This should be started ASAP. This has a provisional hand in time and date of 10:45 Thursday 2 March. Please see Canvas.

Week 3

Well the cyber attack messed us up:

• Assignment 1 is pushed back one week.
• We will skip Section 3.6. Section 3.6 is possibly of use for those going into Structural Engineering, and so video lectures will be made available for those who are interested… but the material will not be examined.

Week 4

We finished Chapter 1 on by looking at applications to temperature distribution, where the Jacobi Method is used to find approximate solutions to a diagonally dominant linear system.

If you want a deep dive into the temperature of a plate stuff there is a post here which explains — in great detail — how the ‘iterations’ are actually physically meaningful.

We had some tutorial time on Monday and again on Thursday, but as ye were doing so well we actually started Chapter 2.

Gaussian Elimination Tutor

If you download Maple (see Student Resources), there is a Maple Tutor that is easy to use and will help you with Gaussian Elimination. Open up Maple and go to Tools -> Tutors -> Linear Algebra -> Gaussian Elimination.

Week 5

Bar tutorials on Mondays, we are now going to push to complete Chapter 2 as soon as reasonable.

20% Written Assessment 1, 8 March

Please see Canvas for more information.

Week 3

Unfortunately the cyber attack put a spoke in our plans. My plan is to keep the same assessment dates, but skip Section 1.9. When we get to that time, I will share the lecture in video format for very motivated students, but otherwise we are just going to skip this section.

Week 4

We did some further study on the Euler Method. The global error with the Euler Method is and we need to reduce this by coming up with a better method or adjusting the Euler Method.

We started this by looking at Huen’s Method,.

In VBA we finished off the Euler Method Lab 2. People who have not complete this lab in the two labs of Weeks 2 and 4 should really complete this in their own time. Help here.
