GCE A Level H2 Maths Paper 2
-
yes. that was how i got 485. 7650 is simply too large man.
-
hmmmmmm L>>
-
how to do the poisson 1 the part where they ask why it's not a good model???
-
i dunoe wad to write also. i just randomly say that mean = 90 is large, thus poisson dist will not be accurate.
someone told me after the paper that we r suppose to write that it is poisson applies to rare occurences. so when applied on 50 weeks timespan will not be accurate.
-
poisson is average per week. i wrote that sales flucuate monthly and hence it is not accurate for 50 weeks timespan.
my probability i got (i)0.5 (ii)0.512 (iii)0.109
PnC i got (i) 120 , (ii) 9 (iii)210 (iv) 485
so far.. only complex wrong ): hope for 90s range >< -
oh ya then what is the complex no ans?? for the angles?
-
i got 0º and 36º.

imba. -
but the question say the argument more than 0 so is it only 36?

eh radians leh.
I think my maximum argument wrong, and as for the minimum arguement.. by drawing the argument would be zero. but they tried subbing in the equation for complex numbers, they got a angle very very close to zero, but not zero...
I keeping the faith that this paper can push up my very screwed maths paper 1

to an A?
-
yeah an A. can only hope for the A.. sigh.
-
yay thks I got that ans too=D
I screwed up my P1 also!

oh yeah.... shyt. my paper 1 is much better. i suck at paper 2. :(

-
woah the solutions are out?? Haha yeah can count how many marks I lost=X
-
wah... sian. the complex numnber.. my first diagram was correct.. then I hand itchy go change... zz another 2 marks gone. damn.
-
Woohoo !!! i got the complex correct !!!!!!!!

imba.... u going to take math in uni or smth? -
what do u all think the cut off for A in Maths will be like ah? I screwed up paper 1 really badly (around 66) but paper 2 pulled me up (around 90) so overall should be around 78. asked around and quite a number of people were predicting that the cutoff for A is around 80!!!! like wth!

78 to 80
around there
You still stand a chance for A

is it that high? -

There are always a lot of high scorers for maths
