EVERYTIME I TRY TO FLY, I FALL WITHOUT MY WINGS.....

totally feaked out during maths test..

analysis as follows"

Question

1) Find the constants A,B,C for partical fraction

x2-4x+11 / (3-x)2(1+x)

response: got it worng i think.. i for A = 0.25, B= 1.5 and C = 0.25 =x

ii) expand (1-x/3)^-2
response: didn't study bionimal so left it blank.

iii) hence... find x^2 term....
response: i didn't even do part 2!!

2) Usuaing analytical method, find the solution set of the inequality

3/x-1 + 5/(x-2)^2 > 3/x-2

response: what is analytical method??

b) hence solve....

response: another HENC QUESTION! IRRITATING!

3) show sumation bla bla bla

response: i onli realised how to do after the paper =x

4) IN 1995, man earn 25,000 and spend 23000. next five yr, salary increase 5% p.a. and expenditure increase 3% p.a. find how much he save.

response: yay! one question can do!

5) SEquence of real no. y1,y2... is usch that y0=-1 and for all non-negative integers n, y(n+1) = 3yn+ 4. Prove by metitcal induction that yn=3^n-2 for all non-negative intergers of n.

response: left it blank..

6_ Functions f(x)= 1/1+x^2
g(x)= ln(2-x)

sketch f(x)

response: copied form graph calculator

ii) largest possibe domain that f is 1-1 function. hence define f-1 for this domain.
response: domain should be correct la.. but i just write no calculation. And how to define?

iii) determine weather gf-1 and gf exist, if it does find rule and range
response: correct! =) i got my double digits!

7) sketch graph 2x-1 / x-1
hence find
f(x/2)-2 and -3f(x+2)

response: anyhow draw but seems correct. =)

8) ALan decide to lose wait bla bla bla..

response: walau matrix question but i go do stupid calculating! got all the values wrong!

9) verify bla bla bla
response: correct but 1 mark whats the point

ii) express in form (r+a)^2 + b then put in sumation form

response: can express but cannot form

10) some wierd curve question:

response: wth! i give up la!

as you can see maths was horrible. left 37 marks blank.. paper was upon 70. =x
If i can pass, i be NizHen for 1 mth.. (vegetarian) haha

Chinese oral was bullshit also.
firstly, i was the last person. waited 1.5 hrs till my turn..
then they ask some stupid question " is reading comics good?'

since a bullshit question requires a bull shit answer, therefore i bullshitteda ll the way.

the teacher seems impressed. hmm..

And MF didn;t want to wait for me cause she want to go home and sleep.... RAA!
