Yeah

Also it's unlikely to come up by the volume of a sphere is 4/3*pi*r^3 and the surface area is 4*pi*r^2

Guys, should I do the rest of the Solomon papers I haven't done or do the R/IAL c2 papers? Which is harder?

Which is likely to expose you to an different way of asking a question than in past UK papers but is on the mind of current edexcel examiners?
R and IAL

The spec is very generalised, they can ask the questions in lots of different ways including ones that you've never seen before..

Is it just me or are the reserved papers harder than the standard papers?

C1 was very straightforward yet a lot of people found it challenging because of the way it was set up.

C2 is going to be a huge bitch, but let's hope for easy, time-saving marks throughout...

Are the R papers always supposed to be more difficult?
Like I know its still stuff from the spec but I've heard its harder than the normal papers

That's in the formula booklet, under the C1 page :smile:

Yes. 2013 was an example where a lot of people suffered from having to sit the R papers.

Do people really think it will be harder than the June 2014 paper. I certainly doubt it

cool

when it says independent of 'x' it means there basically should be no 'x' term, i.e. it should be x^0

so you need to find the point of expansion where the 'x' term and the 'k/x^2' term cancel each other.
this happens when 'n' = 5.
so you get: (15C5)(x)^15-5(k/x^2)^5
--> (3003)(x^10)(k^5/x^10)
the x's cancel eachother out
k = 2, from part a)
2^5 * 3003 = 96096

I'm nervous. I'm going to sleep early tonight after chilling out a little, wake up at 5 and do some last minute questions (not a full paper). Target areas: learning volumes/SAs of shapes, transformations of sine/cosine graph & practise applications of differentiation.

Good luck guys. May the odds be ever in your favour :wink:

There is no transformations of graphs on c2
