DISCUSS:MATH PAPER 1

[Angraiz]

I think it was:

(x + y)(x - 2y)

 

[aaakhtar19]

=x^2 - xy - 2y^2
=x^2 - 2xy + xy - 2y^2
=x (x - 2Y) + y (x - 2y)
=(x - 2y)(x+y)

 

[aaakhtar19]

Angraiz is rite

 

[shahoo]

wat was da shape of dat graph (Distance Time)
Was dere any curve or 2 straight lines
i did dis

0-38 a strate line
38-108 another strate line

Well I got a curve for the constant acceleration and then a straight line... Am not sure thogh.

The part where money was being shared was it $40 and $24??

yes it was $40 for jane and $24 for ken

 

[hassam]

i gt it ronggggg

Right then!!!!!

 

[Jezla]

And what was the value of n for that 160n Q?

 

[shahoo]

lol,this 160n question freaked me out,got it rong.. wat was the area of triangle in q23.plz tell me

 

[Jezla]

Area was, i think, 480...
160n- Igot 21 am not sure f thats right!!!!!!!

 

[shahoo]

mine area was also 480..chill....!!!!

 

[taha waseem]

u all have so many doubts but still saying the paper was easy.

 

[M.Usman Khan]

n= 2 x 3 x 7=42

 

[hassam]

yar guyz 160 out of 180 will be a star na!

 

[M.Usman Khan]

still cant believe the cambridge couldnt give us a more difficult paper

half of my friends had finished it in 45min

 

[sjs]

it was hell easy...!
i just doubt the tangent question...what was the gradient of the tangent? the acceleration one?

 

[Aizen]

i got 0.66 but 0.75 is correct..i guess

 

[sjs]

i got 0.66 too!
it was 2/3 ...thats 0.6667

 

[Aizen]

i also got 2/3, but almost 90% candidates got 3/4=0.75

 

[UxaiR]

i got 0.66 too!
it was 2/3 ...thats 0.6667

the acceleration range was 6-8

so cHILLLLL/

 

[UxaiR]

can anybody tell me the center of rotation in transformation .!
