FYI The question from the 2009 Extension 2 Paper was:
$Let $n $ be a positive integer greater than 1. The area of the region under the curve $ y=\frac{1}{x} $ from $ x=n-1 $ to $ x=n $ is between the area of two rectangles, as shown in the diagram.$\\\\ $Show that $\\...
Prove that \frac{a}{b}+\frac{b}{c}+\frac{c}{d}+\frac{d}{a}\geq 4
\\and \frac{a}{b}+\frac{b}{c}+\frac{c}{a}\geq 3
Or just tell me what steps I take so that I actually understand it. Thanks.
(I know this is one of the easier proofs but meh)
I'm attending Heritage Chinese at a Saturday School. It's much less difficult compared to Background Speakers course. Look at the character list and syllabus for more info...it's just like a Chinese school class.
Out of 9 subjects, I got 7 Oustandings (A) and 2 Highs (B). Principal's award. I'm pretty happy about this...since end of yr9 I've been working much harder and it's paid off!
