Weekly note 3

This week we have covered proofs in section 1.5 and sets in sections 1.6 and 1.7.

Next week we will finish with Chapter 1 by looking at functions (1.8) and start on algorithms in Chapter 2.

Below are 5 excercises that you are to solve and turn in to your section teacher before noon monday september 19th. Remember to mark your solutions with the number of your section and the name of the section teacher. Also below are few extra excercises that you can use to practice on and make sure that you have understood the material. Some of them will be solved in the sections if there is time.

Homework 3

  1. Exercise 12 b), e), i), n) in section 1.4 on page 52 in the textbook.

  2. Exercise 28 a), d), f), i) in section 1.4 on page 54 in the textbook.

  4. Exercise 22 in chapter 1.5 on page 75 in the textbook.

  5. Exercise 44 in chapter 1.5 on page 75 in the textbook.

Hand these exercices in before noon monday september 19th.


Also take a look at the following excercices:
From section 1.4:
3, 11, 15, 27, 31.
From section 1.5:
13, 23, 27, 45, 53.

Please note that the above exercises are for you to practice on, and that they are only useful to you if you try to solve them yourselves (not by looking at someone else solving them!). The exercises in bold are more "interesting" than the others and it is more likely that they will be covered in the sections.
