# AQA A Level Maths Core 1 - 18th May 2016 [Exam Discussion] Watch

1. (Original post by musslih)
OH MY GOSH that was the hardest paper...... it was kindof harder than Past Year Papers.... Can we discuss some stuff here?

1. Question 5b, what was your coordinate of B?

2. For the integration question ( was it Q7? or 8?)
a)what was your x- coordinate for Q?
b)what was your equation for the tangent at P?
c) what was your area under the graph? (referring to the same qn)
i believe b(-3,4)

integration = 20.25
Q = (-5/4 , 0)
Cant remember my P line
Area = 20.25-9 = 11.25

I got this but didn't have time to write it in the order they asked, do you think ill lose marks?
probably not, as long as it is written somewhere clearly
3. What equation did everyone get for the discriminant to work out k??
4. (Original post by Calzs34)
Could anyone explain how they got 11.25??

I got 27 - 4.25=22.75 ? Was my first bit wrong ?
integral was 20.25
triangle PQ was 9 ((24 x 3/4)/2 = 9)

So area is 11.25
5. (Original post by marcelux)
what question?
the equation for the tangent
6. what question was the integration one and what did it ask?
7. (Original post by marcelux)

Ugh, i obviously did -8 instead of +8. And I didnt know how to work out the triangle. Would I lose 2 marks and get 3/5 here?

And as I attempted to find the area by doing my area - my integral would I get 1/3 or 0/3?

I'm hoping I haven't lost marks anywhere else :/.
8. For the coordinates of Q, I don't think I wrote (-5/4,0) I just wrote -5/4 - did you have to give the full coordinate? It was obvious that y was 0 :/

i believe b(-3,4)

integration = 20.25
Q = (-5/4 , 0)

Area = 20.25-9 = 11.25
I think i got the coordinates of B correct...

I got Q(-7/4,0)
for the tangent, it was y=-40x-56, although I'm not sure if its correct or not.
Which leads to the area under the graph = 13.05 units^2... my integration was 20.25 too

I got p as y=-32x -40 not sure if it's right though. ****ed that paper up big time.
11. i thought the circle question was solid
12. I didn't find it too bad, but I'd be surprised if the grade boundaries weren't a little lower than usual. All the numbers were bigger! D: (45 x 7 I mean srsly that's what calculators are for)
13. When will the question paper for C1 be released? Anyone?

Yeah i recall the line as y = -32x+40 that then leads to x = -5/4

And regarding another question about Q, the answer doesnt have to be (-5/4,0), as it only asks for x anyway so -5/4 is fine.

I thought so too! There were lots of big numbers, and also some fractions, which is irritating
16. I didn't get that for b coordinate, I got something with -7 because c was the midpoint🙈🙈
17. My whole class found that paper really hard. We literally spent the rest of the lesson we had left discussing the paper. Feeling alright but I've messed up question 11
18. I got the triangle as 36 as the coordinates of P were (-2,24) and R which was on the X axis was (1,0) therefore I got 24/2 x 3 = 36.

Then triangle (36) - under curve (20.25) = shaded (15.75). Of course I'm now bricking it as the majority are saying 11.25 😰

Next year during 1st week of May

Yeah thats right, from that u got the x co-ord as -5/4 good job
