Week 6

    Since it was the thanksgiving long weekend, there were only two lectures this week. I don't think there was a tutorial either. It's still midterm season so most of my time was spent focused on other courses and therefore, unfortunately, don't have much to say in this entry about CSC165. What I do remember is more proofs. The structure of proofs, including the indentation and reasoning, was stressed. Prof Heap went through five proofs. 

   

    First was a proof of non-Boolean functions, where rather than a true or false value, something such as a number is returned. The second one was using more of the definition. Both of these involved a statement involving the floor. I had no idea what that was so seeing its  symbols that looked like the absolute value |x| with legs kind of threw off the slight bit of confidence I'd built up about this course. Google always comes to the rescue though so now I'm okay with this.Third proof was about how to prove a false claim. Here we could negate the statement and then prove it which was pretty interesting and it would have taken me some time to figure out that approach on my own. Fourth, proof by cases wasn't so bad; it was a longer process but it made perfect sense. Lastly, the proof about limits was where he lost me for a good amount of time. I still need to review all the lecture notes to become more comfortable with everything. 

    

    Also, assignment 1 marks didn't turn out so well...which means I clearly need to work a lot harder. Assignment 2 was just posted and I haven't gotten a chance to look at. As much as I would love the challenge, it does make me nervous. Let's see how this one goes.
