Anyone who wrote CIE AS Level Maths Paper 1 today?

[Diablo]

I don't really mean anything, but you guys should stop worrying about how many marks you're going to lose. It's going to make things worse  just try to make up all of the mistakes by preparing for the next math paper.

man i was pretty sure my answer was correct too....i put it into the equation and all....but now people are saying its 6.... i got something like a=4.76....

[cashem'up]

hey guys wat abt the last question where no sloutions were required for f(x )= k.... i got less than -1 and greater than 7....fingers crossed if this rite i should get 74............damnit last q ans should be in range 2.8 and stupid me wrote 0.34...arggh...

[ifraha18]

how did u ppl do this Fx=k has no solution in last question....


can nione solve it
it ws 4_3sinx=k has no solution

[cashem'up]

how did u ppl do this Fx=k has no solution in last question....


can nione solve it
it ws 4_3sinx=k has no solution

wat was ur ans......nething similar to mine.....

[ifraha18]

i messed this up real bad...i took a very stupid method to solve it..can u solve urs here..

[cashem'up]

one way is looking at the range of ur graph.....easy above 7 and below -1
or u can take max value of sinx and min value of sinx that is -1 and 1 and sub in equation where fx should< k ...got it and u get two ranges......where on a value of k no solutions

[MAF]

-1>k>7.
that was the answer. i m sure about this.
i drew graph of 4-cos3x instead of sin.
man i m such a moron.
how many marks are they gna cut for this?

[ifraha18]

haha,,,i took square n den deb the discrimant equals to les thn zero.. lol

[Samir]

It should be 1 not -1..

[Samir]

+1>k>7.
4-3 (sin270)= 7
4-3 (sin90)   = 1

[MAF]

yes, you're right.
typo mistake.

[Freaked12]

-1>k>7.
that was the answer. i m sure about this.
i drew graph of 4-cos3x instead of sin.
man i m such a moron.
how many marks are they gna cut for this?

2 marks were for this part so i guess -2 cos u basically did the whole part wrong

[MAF]

oh...  well.
waisay i thought misread=1 mark. 
but i got the wrong value for A in the range cos of my wrong graph too. dunno if tehy'll allow error carried forward for that.....
I messed it up good and proper.

[Samir]

I too had a wrong graph and wrong value of A...I think there wont be an error carry forward cos question was of only 1 mark....but lets C...By the way way how many marks did diagram question carried ??
M sure A value one was only 1 mark...
