Wah you long term memory, the numbers remember until so
exact.
My friend tell me plot graph for that question. How did you play
around with the calculator? That's the question I didn't know how
to do in the paper. Horrorrr. Question 9 (iii) and (v). They are
linked, so too bad for me =/ I know how to do (iv) though.
Then I also spotted a careless mistake after the paper.
Question 11, the sketching of the graph. I went to draw both the
graph below and above the x-axis when you're only required to draw
the one above. Sigh =/
