This week's class, we learned about prove whether a function belongs to big-Oh set, and we learned about proving big-Oh by using limit techniques in Friday's lecture. On Fridays lecture, Danny had to write notes on the blackboard for some technological problems. Surprisingly, this is better for my understanding. His writing on the blackboard is much more clear than the writing on the powerpoint. He used to throw his notes all over one slide when using powerpoint for lecture. In contrast, on the blackboard, the notes are more organized. I am glad that I can take notes without obstacles. Better handwriting does help understand the course material.
The tutorial this week is helpful as usual. TA needs to spend more than an hour on explaining only two questions. That is the reason why the explanation and the analysis is clear and easy to understand.
The biggest challenge this week is the second term test. I was very frustrated last week when I heard about it because I was totally not prepared for it. I treated as the most important task in this week's study. However, I should have written an aid sheet before the test so that my format of proof may be better. We are not told if we are allowed to bring aid sheet so that I did not prepare one. The characteristic of this course is that material in the lecture is harder than the questions in the test. I did alright in the test. I am pretty sure the first and the last question is correct. I did not know how to solve the second question. I did not prove the negation. I proved the statement directly to show it is a contradiction. I am not sure if it is correct. I always have trouble understanding the statement when the statement has a lot of quantifiers.
