Could do with an unofficial mark scheme lool

haha yeah thats what i got!
it was weird...
I got something different as I think 3log(x) is not in terms of x. So I got:
y=10^(3*10^x+ whatever c is)

Maybe I am wrong someone correct me if I am
5. Re: OCR MEI C2 MAY 18th
how many mark would i get for the log question if i worote it like this

y=10^(x^3+2)
6. Re: OCR MEI C2 MAY 18th
No! I didnt know the trapezium rule initial limits were 0 and 0!!

How many marks would I lose
7. Re: OCR MEI C2 MAY 18th
I've definitely failed this one s:
Ohwell, most of my class said it went badly so I won't be the only one resitting in Jan

I dont understand how a straight line can be x^3? Even in terms of x

I'm not sure but I put one of the limits at 0 and the other as the last value before the 0 because it said something about 6 strips idk I got confused
Hopefully you won't lose too many!

I thought it went OK but the more I've heard other people talk about answers, the worse I believe my mark is

This always happens to me too! Hopefully we both did alright!

I'm guessing that was 100x^3? Seems right when I plug in the numbers. Gutted I didn't get that , plugged in Log(17) = nlog(5) + log(a) and Log(5) = nlog(1) + log(a). Not sure how many marks I'll lose here :/
15. How did you work the last question out?

16. Re: OCR MEI C2 MAY 18th
I'm feeling pretty confident on everything except the logs question, I did something weird and it made sense at the time but not now XD Did anyone else have trouble on the last part of the last question? It took me like 20 minutes but I eventually got it, but most other people I spoke to haven't and the ones who did do Further Maths like I do.

Also, is it bad I found FP1 (which I also sat today, as well as ELEC2 D':) easier than C2? Or at least a lot more enjoyable XD
17. Re: OCR MEI C2 MAY 18th
any1 in the process of making an unofficial ms, really wana see it :P Thanks

Need someone to check this. There's probably an easier way that I've missed out.

19. Re: OCR MEI C2 MAY 18th
Please someone answer me I just realised I didn't put my calculator into radian mode when calculating the question on the sector. OCR wouldn't give my any marks for that then Im guessing and they'll mark me down for making that mistake? Im so annoyed with myself!
20. Re: OCR MEI C2 MAY 18th
Seeing as the sector area and arc lengths already deal in radians regardless, it shouldn't matter.

Anyway, what was Q10 again? I'd just like to go through with myself and confirm something.
