Assume

For last week the major of what we studied was the Assuming and Prove by cases. Proof by cases`s method was to split your arguments into several pieces and prove it one by one. This was more like using the mathematical way to solve the whole problem. For instance, sometimes we using product rule to solve the statement.

Compared with the logic problem we learnt before, in my opinion, I prefer proving these problems than proving logic problem. Logic one use more brains than prove the cases. Although the logic was interesting, I still like the easier one:).

Week end again,the first test mark published to me. I was not got a good mark in test, 60 percent was not enough for my following course. I need do more and work harder on this course. Try to understand all the logic theorem. Strive for higher mark in next test!

Folding Experiment

Time flies when you were indulged in something. Same with the university life.I have just found I spent more than a week in U of T.Learning was always be the main theme of everyday. Last week, Mr Zhang played a small experiment with us which was to help us understand the problem of logic.

It was really a interesting experiment. He required us to folded a strip paper and stretch it to half again and again. Then after several times stretching, counted both the number of the paper and the direction of the vertexes. At the beginning, one or two times stretch was easy to count the number and the direction. However, after five or six times stretching, it`s became more hard to confirm the solution. My and my partner made a few mistakes when we were counting the direction of the vertex. Please do not think it`s just a small mistake, even a small mistake can destroyed the whole research. Finally we got the answer which was as same as the teacher`s wrote on the board. It cost us a lot of time on distinguished the direction of the vertex. Although the experiment was not so hard, we still need to use a rigorous attitude to face it.
