C2 Official thread

[Hadi Murtaza]

guys what other proof except for the sum formula shoold we know for c2?

None, only sum of geomtric sequence has been asked for last 4 years. It wuz asked once in June 2012 paper

part A just find the mid point of line AB
Part B find the diameter using d=sqrt of ( change in x)^2 + (change in y)^2
and divide it by 2 hence getting the radius
and subtuite in the equation (x-a)^2+(y-b)^2=r^2 where a and b are the center coordinates
part C substuite the X co-ordinate given in the equation u got in part B and solve u should get the value of y he stated
Part D Find the Gradient of the Radius at this point by using the co-ordinates of the center and the given point
use the negative recipricol for example if u got 5 negative recipricol is -1/5
then use y-y1=m(x-x1) where y1 and x1 are the points given in the question part D

thnxx aloot ! ) and good luck tmrw

Which part ??

Part D but i got a reply!1 thnxx and good luck

haha dont expect to find any

 

[chathumus]

Do we have to know transformation of the sine and cosine graphs? I'm dreading this paper.

 

[chathumus]

I'm sitting this paper 2 hours after everyone else since we've got a clash, just sayin'. Don't think we'd have access to phones and stuff to look up any discussions or ask anyone whats coming but I'm hoping we might get some sort of a heads up. Don't really love the idea of cheating though..

[chathumus]

Somebody help, may 2011 Q.5 b) I've left this one out... and can't seem to figure it out

 

[Lilpumpkin]

do we have to learn the proof's? maybe it might come aint it?

Its basic transformation so you apply the thing in the bracket to the coordinates given. One minute i'll do it and help you out
