## Assignment 1

Assignment 1 has a hand-in time and date of 12:00 Friday 1 March (Week 5).

Read the P.51 and P.52 instructions carefully. You will be submitting an Excel file, and written work, including a print out of your Excel work.

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.

The files you need to complete this assignment have been emailed to you. If you don’t want to calculate your and they are calculated in MATH7021A1 – Student Data.

We have now covered enough in class for you to do all of the Assignment. I recommend that you start ASAP.

**WARNING!**

This gives a good opportunity for collaboration but remember collaboration does not mean one student solving the problem and everyone else copying that student’s work. I demand originality of presentation here and you should at least understand what you hand up. If you are unsure of what I mean by this please email me immediately as if I have students who have clearly copied the answer word-for-word from another student they will all be sharing the marks.

Start early so you have enough time to complete the assignment properly and get good learning from it.

**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.**

## Week 3

On Monday, we looked at applications to temperature distribution, where the Jacobi Method is used to find approximate solutions to a diagonally dominant linear system. We also had about ten minutes of tutorial time with this.

On Wednesday we showed the following video, which shows how the approximations to the solution *iterate:*

Wednesday am we did a Linear Systems Concept MCQ followed by a tutorial. Wednesday pm was another tutorial.

I had planned to start Chapter 2 — the method of undetermined coefficients for solving linear odes — on Thursday, but decided to have one more tutorial on Chapter 1.

## Week 4

We will most likely have four lectures on Chapter 2 — the method of undetermined coefficients for solving linear odes. If we make good progress we might get some tutorial time in.

## Study

Please feel free to ask me questions about the exercises via email or even better on this webpage.

## Exam Papers

These are not always found in your programme selection — most of the time you will have to look here.
