3a where dot product =0
10a) idk

I solved your question .. was piece of cake.

Question 10, part (ii). Do give an explanation as well. Thanks.

Anyone?!

Count me in as well.

u also pay up

Your comments seem like you actually have the paper

hey has anyone answered this question 7 from this paper cz i forgot if u did can u guyss explain it to me esp the last part or if u have already done that then just tell me where u did that thnx

p1 GTs are high, so a single mark can make difference in your component grades

Question- 10 (a)
http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w11_qp_12.pdf
Question- 3(a)
Please.. Thank You

Let a =x and the largest --> Last =4x
Un=x+(n-1)xd=4x
nd-d=3x
d(n-1)=3x --> (n-1)=3x/d
S6 = 3(2x+(n-1)d)=360
120=2x+3x/d x d
5x=120
x=24
smallest sector = 5+5+24xpi/180 x5 .

Anyone?!

Put in the values given i.e. x<=1 into g(x)
you would get g(x) >= -9

u wana risk it xD .

Well I'd leave it for the end.. If i have time do it or else it can go

Anyways today will be a rest day for me... Won't solve any questions.. just look at the past papers and grasp how the question is done. Guys just pray that all us get good grades in the upcoming examination.. and whatever comes in the paper is from our knowledge and we can solve it easily and don't find it difficult (especially for the chemistry and physics papers).

May Allah grant us all the grades which we desire and do what's best for us...

thts y i put my safety marks not at 60 but at 65+ safety mark for p1 and 38 for s1 .

dont think that way! one mark can actually help u to go from a B to an A

well like i said .. i'd have left it for the end then

an A2 friend of mine had got a B in p1 and a A in s1 . and he still got an A :O . idk how it was possible

How did that sign magically flip from <= to >= lol?

I never understand how these peeps at CIE distribute marks .. I mean sometimes .. questions which require quite a lot of working are of 2-3 marks .. while questions which get solved within 4-5 lines are of 4 or 5 marks :\

You need 95-100 marks total. Both including S1/P1 for an A.

its fg^-1 = h its not a long working u know

no u need 98 + in maths cause its lowest has been 95.

it is possible if he got a very high B in p1 like few marks away from A and a high A in s1..then its super possible!!
