Anyone who wrote CIE AS Level Maths Paper 1 today?

x less than 1/2 and greater than 5/2?

yeah i guess but i left the half part out

[IGCSE hater!]

lolx its ok..i i wrote x less than or equal to 1/2 and greater than or equal to 5/2 but i dont think that was correct

[Diablo]

What were the values of P ? (in the vector question)

What were the values of P ? (in the vector question)

part i) p was 5


part ii) p=4 or p=-2

right?

[Diablo]

Yeah, I got 5 in (i) most likely. But for some reason I couldn't get the right value for (ii) XD.

[Sticky]

I think it was 3 and -1....

nop im sure its 4 and -2, i asked a whole load of students

[Samir]

My bad ..it was 4 and -2....I think it was 9^.5 + 1
hey u remember the equation for finding k...or how u got k. ??

[ifraha18]

p was 4 and -2

[ifraha18]

it was (x-2)^3/3 with limits 3 and _1...when puttin the _1 limit i cancellecd _3 with 3 insteading of makin it -27?3..??rest vrithin ws corect howmni mrks wil get deducted.

[ifraha18]

find the set of values of k fow ehich 4_3sinx=k has no solution..how did u do this.?

[ifraha18]

my tangent equatin was y=5x-4.5

[Freaked12]

I messed up binomial theorem  (first part)
and f(x)=K last part

Thats pretty much (hopeful of 70/75) it


and the area shaded was so easy
you had to find the area of trepezium
and th*n area under curve with limits of -1 and 3

and subtract them.

what was the value of 'a' in question 2? where the volume of revolution was 24pi?

[Freaked12]

what was the value of 'a' in question 2? where the volume of revolution was 24pi?

it was 100 percent a=6

i confirmed it by putting 6 into the equation in my calculator to find the volume and it indeed gave 24pie

[ifraha18]

i mde a very silly mistake in the shaded area..but i thnk only one or 2 marks wil be deducted...wen puting the _1 limit i cancelled the -3 by the 3 in the denominator...instead of takiin its cube..:(n den divin it
