I done the exam today, MCP2, C2

It was wierd, i could not distinguish wether i did good or bad.

Also at the end of the exam, i was writing down my answers on a additional paper (the spare papers if you ask for 1), and the invigelator came and took it off me and added it to my actual paper.
I placed big fat crosses on the additional paper but at the top of the paper i had written all my answers in very small writing.

Is this going to be a problem? :confused: I didnt cheat or anything :confused:

Also the invigelator requested that i write my name candidate number on that additional sheet, i refused to do so, and he just took it and placed it behind my actual paper.

Please let me know ASAP, im **** annoyed :eek3: :eek3: :mad: :mad:

is this the q where we had to find the co-ords of b? i honestly cant remember the q but i think i got (3,2) or something like that..


I got (4,2) =/

And whoever did the C1 paper. What did you get for the intergration question as the area? I always sucked at intergration but I think I ended up with

18-(42/5)=48/5? Right or wrong answer?

Yeah nice paper, i got p= -3 and q = 3.
OMG! was it really 48/5 i spent ages on this....

i got something like 32/5 - 32/10 + 18


but then the area of the square was 9 times 2 and i thought you had to minus 18 from 48/5 stupid stupid me! AGHHHHH
aha i left the last bit blank had a bit of a mind blank but yee youre right it would be 48/5

Nice paper overall, but how did u "deduce" that in 6C there were no maximum points on the curve?
I kinda shown this but i did a whole separate page of working out for 2 marks..seems wrong :smile:

d2y/dy2 < 0 was impossible because you had to add 2, they were all greater then 0 so no maximum points.
I had a mind blank through the whole of core 1, was panicking so much, it was a nightmare!

well imo (either that or im being stupid right now) but d2y/dx^2 = 2+ (3x^(-2.5))/4
so if u put very low negative value you will get negative answer, however i calculated from dy/dx where would the minimum point be and that there is only 1 stationary point and that at this particular value d2y/dx2 >0, but that seems like too much work for only 2 marks :P

for 8d.) where you had to work out the xcoordinate did anyone get 0?

d2y/dy2 < 0 is possible but if you found the two stationary points both had positive d2y/dy2 values hence minimums and no maximums

Just looked in another thread, can confirm it's actually 0

EDIT - Conflicts now, many say 0, many say 3/4

Yeah I think I got the translation wrong.
I'm pretty confident that I got over 80% though
