WEEK 10

The Analysis of Term Test 2

         In term test 2, I lost most of my marks in the second question.

        I wrote it wrong in the beginning. I proved this statement rather than disproving it, because I did not see the problem carefully and even did not realize this statement was wrong. This error explored my scarcity in the ability of solving this kind of problem, and my carelessness. Maybe I was too nervous which directly resulted that I did not finish it at my normal level. I think I should adjust the good state for the next examination.

Inspiration From Others

    From A.M’s experience (http://am165.blogspot.ca/2014/10/test-1-results.html), I realize that I need the spirit that figure out every single question clearly, no skip and ambiguity.

WEEK 9

The Term Test 2

I think this time I did a better job than the term test 1. I paid more attention to proper time distribution, and finished all the problems on time. However, I was not sure about the second question’s answer, and I will look at that part more later on. I hope I can get a good mark.

What I Learnt

This week we did more exercise on big-Oh proofs.

When the proof came, all we needed is picking appropriate c and B.

* I got two tips, which were very useful to find c and B:

1)   c should larger than the constant factor of the highest-order term

2)   see what happens when n= 1

Then we could find appropriate c and B.

* When there is more complicated polynomial function in big-Oh, we need appropriate c and B to connect them together, for example:

The Challenging Part

For non-polynomials, we used limit at infinity and L’hopital Law, which were important parts in MAT137. For instance:

Learning this type of proof helped me laid a solid foundation of that part in MAT137, I really appreciate it.

An Interesting Finding

When I read other classmates’ slogs, Albert Xie’s slogs drew me attention, because he added a number of funny pictures and videos into his slogs, which makes the articles more readable and enjoyable. I can improve my slog from learning his. (http://99bugsbutaglitchaintone.blogspot.ca)
