Covid Disruption

We have had a very disturbed time with me catching the covid. DME2C are particularly badly hit. To help ease the situation, we will have a revision lab in Week 10 (VBA Assessment 2 is based on Labs 6 and 7).

Lab 8, which is examinable in the Written Assessment in Week 13, will now be held after Easter.

VBA Assessment 2

See Canvas for the assessment information.

MCQ League

This is currently in a mess. I would invite DME2C students do MCQ VI (below) and submit their answers here.

Week 8

We finished looking at boundary value problems (in particular Goal Seek) and began looking at partial differential equations by looking at Laplace’s Equation.

In VBA, DME2A and DME2B had Lab 6. We skipped Lab 5. DME2C were due to do Lab 6 on the Monday of Week 9 but my covid disrupted this. DME2C should have worked on Lab 6 before Friday 1 April:

Watch this (Links to an external site.) to start you off. Next attempt Lab 6 yourself. Just use Euler’s Method rather than any RK. If stuck, please watch this (Links to an external site.). Any questions please email.

Week 9

I was out with covid. Ye received the following instructions:

DME2 Lectures Tuesday and Wednesday

Watch this (Links to an external site.) and then this (Links to an external site.).

DME2 Lab 7

Watch this (Links to an external site.) to start off. Next attempt the lab yourself. If stuck, please watch this (Links to an external site.). Any questions please email.

Week 10

In lectures we will cover the final section, on the Heat Equation.

In the VBA Lab we will have a revision class. What you do in this class will depend on how much you have done independently in Week 9.

Week 11

In the VBA lab, we will have our second assessment.

Week 12

In the lecture slots, I will do theory/calculation exercises from the notes.

20% Written Assessment 1, 1 March

Week 4

We could avoid the implicit differentiation of k-Term-Taylor Methods by looking at Huen’s Method, which is an adjustment of Euler’s Method in that it uses lines.

We started talking about second order differential equations.

We also looked at calculating a Maclaurin Series

In VBA we did Heun’s Method. Unfortunately the storm messed up the Lab for DME2C and they need to do the lab remotely as per the email, as well as MCQIII.

Further Remark: Heun’s Method

There is a statement in the notes that Heun’s method is of order the second derivative. The exact situation with the Heun’s method error is fairly complicated. The errors depend not just on the nature of the solution but also the nature of the differential equation. For example, consider

  • \dfrac{dy}{dx}=2\sqrt{y(x)}, y(0)=1,
  • \dfrac{dy}{dx}=\dfrac{2y(x)}{1+x}, y(0)=1,
  • \dfrac{dy}{dx}=2x+2, y(0)=1.

The function y(x)=(x+1)^2 is a solution of each of these, but only the third will yield zero errors with Heun. It turns out that the Heun’s method error depends in an important way on how the F(x,y) depends on y; so above we have F(x,y)=2\sqrt{y}, then F(x,y)=2y/(1+x), then F(x,y)=2x+2. How exactly that works we will not get into but we will say:

  1. It is still true that the local Heun errors are \mathcal{O}(h^3), and so
  2. The global Heun error is \mathcal{O}(h^2), and also
  3. Heun’s method will have problems when the third derivative is large.

Week 5

We will continue looking at second order differential equations and how to attack them numerically.

We will begin a quick study of Runge-Kutta Methods.

In VBA we will look at Lab 4, on Second Order Initial Value Problems.

Week 6

We will look at boundary value problems (in particular the Shooting Method and Goal Seek).

DME2C Lab 18 March

DME2C have already been impacted negatively by Storm Eunice. Rather than have them hit again with no lab on this day (for the university is closed for the bank holiday), we will have no DME2C Lab in Week 8, but two in Week 9, with the additional lab held:

  • Monday, 21 March, C125.

I will also set up a remote option for those who would prefer that.

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).

Week 3

We then did some further study on the Euler Method. The global error with the Euler Method is \mathcal{O}(h) and we need to reduce this by coming up with a better method or adjusting the Euler Method.

We looked at the Three Term Taylor Method as a better method. To employ the Three Term Taylor Method we need implicit differentiation, which means more pen-and-paper work.

In VBA we finished off the Euler Method Lab 2. Ideally everyone should have done up to p.130.

Some students did or started Exercise 1 and/or Exercise 2 on p. 130.

Week 2

We looked at the Euler Method, and then started looking at big \mathcal{O} notation, and Taylor Series.

In VBA we started programming the Euler Method.
