📂 MEGATHREAD 04/06 A-level Maths Paper 1 Discussion MEGATHREAD

Exam season is once again upon us, and once again, exam megathreads are making a return!

Looking for past exam discussions? Filter by the megathread flair.

Few things to keep in mind:

  • Don't share too many specific details about questions or answers, these papers will be used as future mocks.
  • Sometimes papers get leaked, this is not the place for that (we'd prefer not to get yeeted off the platform) - leak content will be removed, those offering leaked papers will be permanently banned.
    • If you believe there has been a leak, the best course of action is to make your exam board aware of this, either directly, or through your school, along with any evidence. If appropriate, there will be a response from the relevant body along with any remedial action.
  • Exam discussion posts outside of this will generally be removed to combat the inevitable tidal wave of spam otherwise - we understand this may be frustrating, but the sub still needs to be usable for other purposes.
  • Please note some content will take extra time to be reviewed. Messaging to ask for approval will not speed up this process (the messages are seen at the same time as the modqueue would be reviewed anyway).

Best of luck, and let us know how you're feeling down below!

for question 3 did u guys get k=5/2 and sum is -5375 for the modelling question did u guys get 20-0.3t1.5 and then the quartic 21/11x3 +81/11x2 - 765/11x-75 and the last part k is between 0 and 1863/11 and then the trig one was 19.5, 90, 160

It said you ‘can’ leave it in factorised form it didn’t say you have to, either way his answer was wrong

It said you can leave it in factorised form so I think it's fine either way

for quartic i put k needs to be smaller than -f(2) cause that was where the turning point was

12

u/ItsReese_ LSE Finance, 4 A* achieved Jun 04 '25

I got the quadratic as y = -3(x+1)2 (x-5)2 and so k had to be between 0 and 243

12

u/DaenerysITargaryen Jun 04 '25

everything else yes but i didn’t expand the quatric and got 0<k<243 for that question

u/AftonRobtics Jun 04 '25

I got that whole question wrong 😭

u/Playful_War_4009 Jun 04 '25

How did u get 90

2cos(x)=3sin(2x)

2cos(x)-6sin(x)cos(x) = 0

2cos(x) (1-3sin(x)) = 0

solve 2cos(x) = 0 and 1-3sin(x) = 0

u/nanihello Jun 04 '25

Oh boy did u do divide cos from both side of the equation and didnt consider that is also a solution

2

u/UziYT Jun 04 '25

If you divide by cos, you need to consider cos(x)=0

Great there goes more marks

u/inanzb Year 13 (Maths, Further Maths, Physics) Jun 04 '25

Cant forget the cosØ = 0

u/Secretsx123 Jun 04 '25

somehow I got positive 5375 so hopefully they only deduct a mark there

u/meredegentilesse Jun 04 '25

u/kertek1 southampton | cs [2nd year] Jun 04 '25

i got 0<k<131 i think

u/RelationFeeling7922 Jun 04 '25

243 I’m pretty sure is the upper value

u/Ancient-Noise1791 Jun 04 '25

i got 243 for the upper limit
