## Wednesday 22 February

A one-day only change to the timetable. Ye will have Brendan Walsh at 10:00 and 15:00 and I will take ye at 09:00.

## 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 $\mathcal{O}(h)$ 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.

## Week 5

We will do more on Heun’s Method, and also look at “Taylor Methods”.

We might also introduce second order differential equations and how to attack them numerically.

In VBA we look at Lab 3, on Heun’s Method.

## Assessment

See Canvas for the assessment schedule.

## Study

Study should consist of

• doing exercises from the notes
• completing VBA exercises
