Where to find help for Test 4

Q1: These amount to simple exercises of the sort we did earlier in the semester: a propositional derivation for the logic question, a simple "membership" argument for the set theory, and a truth table for the Boolean algebra 2. In fact, there is a connection between these three, which you may use to simplify your work ...

Q2,3,4: All these are covered by the exercises in Chapters 9 and 10. In fact, Q3 is also remarkably similar to Exercise PG1 in Chapter 10.

Q5,6,7 These examples are very similar to ones done in class and in Exercises 10.2.3. Q7 is also discussed in this exercise set.
Q8: This you may need to think a bit about, but here's a hint:
Difficult not this is, according Yoda to.

Q9: You are on your own for the essays! But a couple of comments about the essays: first, these topics are quite general, and you should regard the entire course experience as possibly relevant in forming your answer. And most importantly, address the question directly. In the past two tests, many of you didn't actually write on the questions asked, but instead wrote on different questions, presumably because you thought that would be easier. I deducted marks for that, and will do the same this time. Read the question carefully, and make sure your answer is relevant to the question.

Any comments?

As we near the end of the course, it's perhaps time to reflect on the whole experience. This has been an unusual semester - two teachers and a period of interruptions in the middle of the course. We (Daniel & Robert) would be interested in any constructive suggestions or comments you might like to make: Did you find the course rewarding? Are there any specific areas that could do with some improvement? If so, where, and what do you suggest?

You can drop either of us a note (paper), send us a MIO or email, whatever suits you best. We can stand abuse, and actually enjoy compliments, but we would really look forward to thoughtful comments from your perspective. (Feel free to tell us you hate (eg) derivations, or whatever, but keep in mind that the main outline of the course isn't likely to change - it's where you think the details can be improved that we would like to know.)

Please feel free to make your comments anonymous, so you don't have to worry about our "finding out" who said what. Eg, if you use email, you can set up a temporary Hotmail account, send the email, and then close the account. We'd like you to feel comfortable to speak your mind. (We trust you folks to be civil and thoughtful!)

A personal comment from Robert: I think you already know that I really enjoy teaching this course. Whatever your thoughts about the subject matter, I found most of you to be willing to give the subject a real try, and I respect your efforts to deal with material that was probably very different from your other courses. And personally you have shown me kindness that is very touching.

Most of you have succeeded with grace and dignity - I hope you found the experience at least half as rewarding as I did! I am only sorry I couldn't see you through it all, right to the end of the semester. I wish you all the best of luck with the rest of your studies at JAC, and beyond.

A personal comment from Daniel: I entirely share Robert's feelings. It's not always easy to adjust to a new teacher midway through a course, but you were open and welcoming from the first day, and I've really enjoyed teaching the course. Best of luck in all your future studies.
