guys how do you find the rotation in transformation when the center of rotation has been changed?
e.g
if lets say it has been changed to (2,2) do you replace the 1's in the transformation matrix with 2's ?

Hi I'd just like to know if anyone has the maths summer 2012 past paper markschemes/examiner report/grade threshold (if those last two are available yet?) the codes I'm looking for should be something like this: 0580_s12_ms_43 (this one specifically), 0580_s12_er, 0580_s12_gt.
I really need these (at least the first one) before the end of the week, so any help as soon as possible would really be appreciated :) Thanks

Can anyone tell me the vertices of the image G with an explanation? In the marking scheme the vertices weren't given.

Thank you in advance.

May/June 2004 {Paper 4 ,0580}
Q-3 (c)
Q-6 (C)
Q-9 (e) and (f)
only
So in Q3c, u have to find the frequency density. U do: number of days/ difference in interval. So for 0<d<20 u would do 58/(20-0) which is 2.9. For 40<d<70 u would do: 147/(70-40)=4.9
For 6c: you have to find the total surface area of the solid. Then, do cost of covering solid/surf area. So the total surface area is part b (324.7)+ 2*3.141*7^2. The total surface area is 632.6. So to answer the Q u do 411.58/632.6=0.65
For 9e: u draw a kind in Ur graph where x=70 the find the higher possible value of y Which Is 38
Hope i helped!
Btw, have u done all past papers since 2003 or 2004?
