The Official OCR C1 Jan 2010 Thread

Hi,

I couldn't find a thread already started about this exam, so I apologise if there is one.

I'm resitting on Monday (11th Jan) and was wondering if anyone could post the answers on here afterwards so we could check them? I know last year Mr M. did it?

Good luck to everyone else sitting this paper :smile:

EDIT: 11TH JAN after exam!

OMG I JUST CAME OUT OF THE EXAM O__O

It was the most challenging C1 paper EVER!

What answers did you guys get?
My centre was (-3,2) and radius as root17
K was +/- 3
n in question 4 was -1
for the last question i got x = 35/16 and x= 3, -11/3
OH YEA QUESTION 7, I picked graphs 1,3,2 in that order xD part iii) I think I put down x^2-9=y but I think its wrong D:
for question 5 I think I had (4+/-root3)^2
for question 8 on simultanious equations one of my x's was -1/3
I found 'a' to be 1.3

Really desperate help needed with these two questions? thank you to anyone who can help!

Jan 05 - question 10 v)

Use the results of parts iii) and iv) to show that the circle which passes through D,E, and F has equation x^2 + y^2 - 3y -4 = 0.

D (-2,0) E (0,-1) F (2,3)For reference these were the question parts iii) and iv) that ive already done:
iii) by calculating gradient of EF show that DEF is a right angled triangle
iv) calculate the length of DF.

June05 - question 10

10iv) given that 24x + 3y + 2 = 0 is the equation of the tangent to the curve at the point (p,q), find p and q.
For reference again these are the previous parts of the question that i have already done.
i) given y = 1/3x^3 - 9x find dy/dx
ii)find coordinates of stationary points on the curve y = 1/3 x^3 - 9x
iii) determine whether each stationary point is a maximum or minimum point.

Try the mathematics forum (rather than maths exams) and pose your questions one at a time. You may need to explain what you have done so far.

I've already sat this paper 3 times, first time i got a C second and third time I got an A, i only missed my A overall at A level by 5 marks though so I need 88 UMS tomorrow. For the last 3 exams i'd done every past paper from Jan 05 until the time of the exam except this time i've done about 5 or 6.

Mr. M do you have the question paper? I'd like to see this :biggrin:

Anyone? D:

Just came out of the exam room for the C1 exam and wondering what everyone else thinks of the paper. Personally, i found it pretty easy up to the last two questions which had a few tricky things in, but overall, as it was C1, it was pretty basic. Wondering what everyone also got for the last part of the last question. There is a big debate at my school atm, and a lot of people got root 10, a lot of people got root 19, and we cant work it out as we forgot the question.

LEave your views and opinions. Overall, it was a hard C1 Paper.

well, it was a very hard C1 paper. i reckon i dropped 5 marks. I missed out 11 part (iv), got the super easy polynomial mapping question wrong by missing out minus sign, and i think i may have dropped a mark on the last question but i dont know. we'll see. **** hard for c1 though. grade boundaries will be low :biggrin:
