## Assignment 1

Assignment 1 has a hand-in time and date of 11:00 Thursday 27 February (Week 5).

See the Week 2 Summary for more.

One final warning: do not give your work to others to copy. If there is a lack of originality of presentation I will be dividing marks between those who copy each other and the person who did the original work will be penalised along with those who copy them.

Note in particular:

- Work submitted after the deadline will be assigned a mark of ZERO. Hand up whatever you have on time.
- Only Partial Pivoting
*has*to be done using Excel. - Note that if you are doing Gaussian Elimination by hand you must use exact fractions and square roots rather a decimal approximation.
- I advise that you do the questions out roughly first because small mistakes are inevitable.

**THIS IS A LEARNING ACTIVITY NOT JUST A GRADED ACTIVITY. THE CHAPTER ONE EXAM QUESTION IS WORTH 24.5% OF YOUR FINAL GRADE WHILE THIS ASSIGNMENT IS WORTH JUST 15%. THINK ABOUT WHAT THIS MEANS.**

**to two significant figures**), Excel is far more suitable.

**two significant figures**(say two or three iterations) — which is no problem by hand — but potentially it could take more (at least six). I don’t really want people spending loads of time doing iterations by hand, so I will give 3/4 marks for Q. 2 if you do six iterations by hand. If you want to keep going – by hand – until convergence (

**to two significant figures**) you can of course get the 4/4 marks – but you need to ask yourself is it worth your time to keep going for the sake of one mark (out of 60… out of 15% —- that is 0.25% of your final grade).

## Week 4

I was late on Monday… so we had a tutorial instead of a lecture.

We had another tutorial Wednesday AM.

We worked on Chapter 2 Wednesday PM and Thursday.

## 09:00 Wednesday 26 February

We will not have class 09:00 on Wednesday. Instead we will have class at 09:00 on Thursday, provisionally in **B185.** Watch this space.

## Week 5

We will hopefully finish off our work on the method of undetermined coefficients between Monday and Wednesday PM. We will have two hours of tutorial on Thursday morning before the Assignment 1 deadline of 11:00.
