Supervisions: Worked Solutions
- It's important to have a go at questions yourself before looking at worked solutions. (See the advice page for reasons why this isn't wasted time, but a useful learning experience.) These solutions are provided subject to the condition that they are not made available to future students before the end of the end of the term in which they first tackle the questions.
- More solutions will appear for some subjects as the terms progress; more may also appear as I get round to writing them and scanning them in. I shan't provide them for all questions, though: let me know if you're stuck on anything for which I haven't provided a solution. Solutions for the Easter term never appear.
- Please let me know if you find any errors. There is a prize of one chocolate bar per error (to the first person who spots it) until further notice. Errors in question numbering do not count. (There are likely to be several of these!)
- In the worked solutions, I've used black ink and pencil to show what I would write as an answer, with red to underline answers. I've used blue ink to make comments and observations as I go along. I've used green ink for digressions. I haven't (usually) re-stated key information from the question at the start of each answer, but it's good practice to do so in your own solutions.

Examples sheet: 1a, 1b and c, 4a and c (where the part labelled b is really c), 4d, part of 5, more of 5, 9c, 13a, 13b and c, 13d (where the units in the question are no longer wrong), 14a, 14b, 17a (some), 17a (more), 17a (even more), 18 (very first part; comments about later part need modifying as the question is now more explicit than formerly), 22a and 22b (or at any rate the finding of the Fourier transforms; again the exact question has changed), 26a, 26b and c.
