does anyone remember what questions were asked in order?
1) is to find gradient of tangent, and co ordinates of B, and ?
2) surd question
3) ?
4) ?
5) circle one
6) ?
7) ?
8) the inequality one with critical values

i can put together a mark scheme

7 was integrating. The integral evaluated to 20.25, and the shaded area was 11.25

Hope it's 73 (or less). Full marks for 100 would be a bummer.


If its full marks for 100 ums on this hardish C1 paper I haven't got a chance of full UMS on C2
Does anyone know the surds part b) question? I know it was ((3rt5)^2 + something) divided by something.

(3√5)^2 + √5 over 7-3√5

Yeah that looks about right, did anyone get 4 as the denominator?
Original post by Poppy1098
I also got root 34


nahhhhh fammmm it was k=65

ahhh never mind, other than that and forgetting how to find a stationary point (really stupid mistake) i think ive done pretty well
could anyone tell me what question number had an answer of -3/2<k<6 ?

I need to know aswell, what was the question

think it was 8, but i got the answer as k<-3/2, k>6

it was K<-3/2 K>6
they were 2 seperate inequalities because B^2-4ac was > 0

It was the last part of the last question, not sure what number. But k wasn't between values as it was 'equation'>0 so you had to give the points that were above 0 making k<-3/2 and k>6

I got -4 as the denominator but I don't think it's right

9? I thought is was 0.5*[24*(5/4)]=15

Hmm, nah it's 9. The base was the difference between -2 and -5/4 which is 3/4.

nah i got -41/whatever as well soooo...
For the sketch the curve question, who got y=8 and then got an upside down 'U' shape ?
