## Test 2

~~Tuesday 21 November~~ Thursday 23 November at 09:00 in the usual lecture venue. You will be given a copy of these tables. Based on Chapter 3, sample at back of Chapter 3. I strongly advise you that attending tutorials alone will not be sufficient preparation for this test and you will have to devote extra time outside classes to study aka do exercises.

## Week 9

We finished looking at Partial Differentiation and then saw how it can be used in error analysis.

## Week 10

We will start Chapter 4 by looking at integration by parts. We might look at completing the square and work.

## Study

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

## Student Resources

Please see the Student Resources tab on the top of this page for information on the Academic Learning Centre, etc.

J.P. McCarthyQuestion 1 is perfect.

Question 2 is good for full marks but you should simplify e.g.

or even better,

.

Question 3 is perfect.

Question 4… you are not fully communicating to me and this is leading to errors. Part i is looking for

.

By not doing that you ended up doing:

,

which is incorrect. Finally, although it wouldn’t cost you marks, you should round the error approximation to one significant figure (so ) and have the same precision (one decimal place) with your best guess of ().

Question 5 went wrong. Start with

.

You are not going anywhere without this. Remember the rate of change of (with respect to time) is , and the units of are the units of divided by the units of :

,

where here means “the units of “.
