last SG · 2009-10-27T17:58:07+00:00

spot on, same instinct as me....i dun noe u sec 4 until now, at hideout u never reveal anything lehFor me,I think human can split into parts meh...So i round...

Sgforum King SG

i personally find it Quite easy except for a few part questions which i didnt know how to do.

I think paper 2 will be hell

Han chiang SG

Ya quite easy. But the question when d=12 what is t is get wrong! I write 4 zzz...

But overall still ok ba. I scared e maths leh. My friend say last year A1 for emaths is 87 marks...

I couldn't figure out the sequence question, and I fell for the trick in question 2. Question said that he sold the watch at 135% profit from cost, I didn't think and put the selling price as 135% of the cost.

There have been disputes for that question. How did all of you guys answer it?

An inverted triangle shaped prism takes 8 seconds to fill completely, and is 24 cm in height. How long does it take to fill 12 cm? Also, draw a graph.

OMG! SG

I find it okay...Didn't manage to do like 4 questions which is like 4 marks fly away...but not sure the rest all correct anot =x hope do well for paper 2~~~

paradoxico SG

For me, t=2. I was rather taken aback by the absence of typical P1 questions like graphs of functions and construction. P2 will probably be as unconventional as P1. =/

yiha093 SG

wa sian dun like u la

i wanted to post =<

paper was easy as hell .

knn prepare to die for Paper 2 already. This paper i finish in 1 hr..

the only more challenging question is the one on vectors, the last question.

personally i feel this year PSLE paper harder than this sia

qdtimes2 SG

wa 87 marks for A1. if this year also something liddat this, after a few careless mistakes, the A1 will say goodbye liaoz.

Qn2: I also think it's 235/100 x 48

The water triangle-prism qn, a lot of ppl say 2 and other people say 1. and i anyhow do and manage to get 2. i guess depth = k(sqrt t) lol

OMG! SG

I get t= 4....then the graph is straight line... towards the end..

the watch i use 235/100 x cost price.

Hope correct =x

ViewtyKU990 SG

anyway these are my spots for tomoro question

graph most probably kind of with 2 turning point (x^3 curve)

circle properties (more of them)

area of a lot of things

polygon

sets notation

trigo

matrices

bearing

probability

and probably another vector question

share your spots here :D

Hope correct =x

wont be a straight line, it will be a curve, answer is 2

and the watch yupp, is 235/100 x cost price, answer 100+ de, not 64.blah blah that one

Music-Life SG

Heh, quite a number of my classmates gave a straight line. Btw, how many managed to find that the sequence was 45 - 7n?

yiha093 SG

nah. i left it blank .

vector was easy.

got the N thingy wrong. they say is - i go put + .

qdtimes2 SG

Heh, quite a number of my classmates gave a straight line. Btw, how many managed to find that the sequence was 45 - 7n?

heh i think almost everyone can get 45 - 7n

OMG! SG

lol..I use 12/24 = x/8 den cross it to get t=4...den straight line...plus they say is constant rate..Can tell how u get t=2? That question i leave blank LOL

ViewtyKU990 SG

yupp i got that sequence

qdtimes2 SG

the constant rate refered to the rate of flow of water.

ViewtyKU990 SG

lol..I use 12/24 = x/8 den cross it to get t=4...den straight line...plus they say is constant rate..Can tell how u get t=2? That question i leave blank LOL

use similar triangle, let length be x

time taken = 1/2 x 12 x (x/2) x8

1/2 x 12 x (x)

limpper SG

nvm luh

governement say ite got future one

Music-Life SG

Another thing, for the Population question, second part asked for the africa population over square kilometres. You guys put 31.0 or 31.3?
