Math O level

Today was the paper 2...Originally posted by dcx:When did this year O level Maths paper start huh??
-
oh no, dxc missed paper 1!
-
Ok...thanks...Originally posted by technoboy:Today was the paper 2...
When was paper 1? -
I think someone close to him taking la... not him... =.=Originally posted by Ah Cek:oh no, dxc missed paper 1!
Anyway... the paper was straightforward la... didn't know why some people did the graph though... the vectors question was idiot-proof... -
you're right.......i'm not the one taking.....Originally posted by DrTech:I think someone close to him taking la... not him... =.=

Anyway...i've took O level almost a decade ago......... -
Last year got vector, this year also got Vector.Originally posted by DrTech:I think someone close to him taking la... not him... =.=
Anyway... the paper was straightforward la... didn't know why some people did the graph though... the vectors question was idiot-proof... Why this year no congruent triangles? -
Wa lao eh i stupid go and do graph lah!! the vectors the appearance like very hard liddat i never do......haiz
the bearing fly kate that one how to do?? angle of elevation -
Anyway, that Quesitons of making toys is consider okok if u notice the Unit..
Not onli this Questions, lots of questions all on units loh..
The number pattern Question, the number of ways he can pay the parking thing.. wat is the formula u all got for the part (ii)?
The construct formula for x y and z..?
I did Graphs..
I think.. Consider okok if no careless mistake ba

tough leh the no. pattern part i duno alreadyOriginally posted by snowiesnow:Anyway, that Quesitons of making toys is consider okok if u notice the Unit..

I wrote n+y=z
cos, It is true loh. LOL
onli that dun have x.......
then i also duno .. anyway it's only 1 mark -
The pattern is actually known as the fibonnacci squence whereby the first two value will add up to the third value, so on and so forth. The answer is infact just x+y=zOriginally posted by snowiesnow:Anyway, that Quesitons of making toys is consider okok if u notice the Unit..

the working for the number of toys should use unconverted values. So answer is 24545 toysOriginally posted by approximately89:answer for the numbers of toys to be made
vol.of cone+hemisphere(toy)= (1/3 x pi x 5^2 x 12) + (2/3 x pi x 5^3)
=575.9 cm^3(round up to 576cm^3)
vol. of metal cylinder= pi x (150)^2 x 200
= 14137166.9cm^3 (round up to 14137167cm^3)
therefore : numbers of toys made = 14137167cm^3 divide 576cm^3
= 24543.69 (round up to 24544 toys)

yeap... I didn't do any revision and last minute looked thorugh the textbook... And saw this word... So I managed to do...Originally posted by DeathEdge:The pattern is actually known as the fibonnacci squence whereby the first two value will add up to the third value, so on and so forth.

Guess it was my luck

wa god is blessing uOriginally posted by technoboy:yeap... I didn't do any revision and last minute looked thorugh the textbook... And saw this word... So I managed to do...

good luck with those who stupidly did the graph......

The graph is pretty easy as well what... -
not tt graph qn is difficult.. jus tt it's more time consuming and ma huannn as compared to the vector one
-
i second that, when i was vetting the paper. i see wah heng ah the two choose one, one dun need to do graph, straight away do vector qn first den go back to first qn.Originally posted by Itachi:not tt graph qn is difficult.. jus tt it's more time consuming and ma huannn as compared to the vector one -
vectors are damn f^*king easy today!

The bearing fly kite one how to do??
-
almost everything use sine rule. Answer 28.1 degreesOriginally posted by The man who was death:The bearing fly kite one how to do?? -
I did vector.Originally posted by DrTech:I think someone close to him taking la... not him... =.=

X Y Z how to find ah?
-
For the circle with lots of lines question...
How to prove that triangle is isoceles?
-
X + Y = ZOriginally posted by redstone:I did vector.
X Y Z how to find ah?
thats the answer... -
One is bisect so = 28 deg.Originally posted by redstone:For the circle with lots of lines question...
How to prove that triangle is isoceles?
The other angle is alt. angles so also 28 deg.
Therefore the triangle is an isosceles triange
