C3 is a generally well comprehended module, so even if the paper isn't too nice, I'd expect high grade boundaries.
The last few C3 papers have been quite nice which is not a normal thing for MEI, so I wouldn't be surprised if this paper was quite challenging.

After that horrid excuse of an M1 paper though, I do feel as though MEI owe us
Regardless, good luck to everyone. All the best, and I'm sure you'll smash it!

this is what i got, the rest were like show that..
  • 1)(i) -3x/4y (ii)-6
  • 2) (i) odd

(ii) periodic (pi/2)
(iii) even
  • 3) (i)0%

(ii)k=0.048
  • 4) (0.55, 0.514)
  • 5) (ii) -1/3
  • 6) (i) 5pi/6

(ii) sin(0.5(x-pi/2))
  • 7) n^3-3n^2+2n. Prove it is divisible by 6 for all positive integers n. I factorized, they were 3 consecutive integers, so at least one divisible by 2 and one divisible by 3, thus it is divisible by 6
  • 8) (i) equation of the tangent: x-4y-3=0

(iii) 23/8-4ln2
  • 9) (ii) find P and Q. P(3,0) Q(4, ln4)

(iv) 4ln2-1

The final answer for the last question I got 4ln2-1? The one where you had to write it in the form mln2-n

I got 25% for the half like one- but why the hell was there like half a page of answer space for that one mark? 😂
