I was doing my Math TYS when I recalled what Mrs Leong said during lessons today. She say someone who had took the O's Math last year had taught the class a wrong method of caculating the gradient of a tanguent. She said the class had use a triangle in the process of caculating the gradient and do not know the right method in doing so. She continued by saying this particular person also took the class that the method she taught was wrong and this "square" method was easiler. At that moment, I was wondering whether she was talking about me as I had drawn a square and some of my classmates had inquire about how the question could be done. I simply tell them to find the gradient and I did not tell them to count the number of squares in the triangle. Neither did I critisise her method. Later she narrowed down to the guys talking A Math and down to the person who got an A2 for their O's Math. I was relieved but deep inside me, I still suspect it is me the teacher was talking about. The whole lesson was so frightening and I hold my breathe till the teacher calm down and settled down on the table. Wow! Who will have thought that Math lesson could be so frightening!
