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.

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![[\cdot]](https://s0.wp.com/latex.php?latex=%5B%5Ccdot%5D&bg=ffffff&fg=545454&s=0&c=20201002)
