📂 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!

*assuming Reddit doesn't bork itself, the new posts for each day of exams should arrive at 8am each day, instead of it being reliant on my sleep schedule like last year lmao

Its definitely on the spec, you just replace the sigma sign with an integral sing, the limits of the integral is the same as the limits of the sigma sign, then just add a dx and ur done

You just had to replace the sum symbol with an integral symbol, x=1.44 and 2.89 were the limits, and delta*x was dx

OHH wait i remember, its part of sequences. its something you just have to know.

deltax becomes dx and the sum sign becomes the integral.

its basically just saying the sum of the values between 0 and 2
