# OCR MEI C4 Mathematics June 2016 - Official Thread watch

1. What did everyone do for question 6? Made up loads of rubbish got R co-ordinate (0,4) and Q (4, 0)
2. (Original post by decombatwombat)
Find dy/dx

Do y -y1 = m(x-x1) to find the general equation of a tangent using x =2t y =1/t

Find the x and y intercepts by subbing in 0 for x and y

Then the Area = 1/2 x OQ X OR = 8 which is independent of t
Okay lol I did all that but thought I was completely wrong. I guessed that t = 1 and didn't say that the area was independent of t so will I lose a mark for not explaining
3. I got the area of the triangle as 8 as well for 6 did anyone get something similar? I don't even remember my method 😂

I got 8 too
you worked out dy/dt and dx/dt
then dy/dx
then worked out line equation
y-y1=m(x-x1)
Then when x=0 y=4/t
when y=0 x=4t
then area = xy/2=8
5. Can anyone remember what they got for binomial expansion I spent an eternity on it and still sure i got it wrong

P=2
Q=-2

2 and -2?

I got 2 and -2
9. [QUOTE=Mr Moon Man;66069181]P=2

Fgs ended up with 4 and -4, must have lost a half somewhere! Reckon I'll get any marks for setting up the equations and follow through for validity?

Same I got 8 for Q6
11. how did you do that ratio question?
12. (Original post by Haleema567)
I got 2 and -2
Got 2 and -2 for Q2
13. Well THAT was a ****ing disaster.
14. (Original post by Daniel9998)
what do you think the grade boundary will be for an A this year?
Maybe 71 for an A?
15. Did people get 4 for the propotionality constant
16. How did people find the comprehension? Think I've dropped at least 5/6 marks on it tbh
17. Some answers I got

-Root10cos(theta+1.249)
-Invalid because4/root10 is bigger than 1
-P=2,Q=-2
-Theta=90,26...?
-volume=16Pie/3
Area was 8
-Q(12/5,8/5,2) not sure about y here
Ratio 3:2?
Last q was show thats
and k=0.811?
18. What did people get for the Cartesian equation of the plane and the angle between the plane and line AQ

Was it not 8pi/3 as it was only rotated through 180 degrees

I got 0.25
