what's the meaning of "NB: Condone use of < "
and in IGCSE January 2012 Maths B Paper 2 No.1 ,can we write the answer in range like 2<x<6?
or just separate x>2 and x<6?

 

[Stancy Motha]

the ans should be written like this that's what we were taught

2<x<6 and dont drop the eqauls sign.don't separate until asked to.
condone means lookover so i guess they meant its ok if u leave out the equals sign but i do no we wer taught it's imp.

Thanks and another question bro...
Jan 2012 paper 2 ...no.6 <d> Maths B...
i don't know how to describe the fully transformation of ABC to A2B2C2.?
i have looked up the marking scheme..but i don't know how they get it?
Thanks in advance

 

[Stancy Motha]

it's sis & u'r welcome
just giv moi sum time to do it ok???
n btw just wondring dont we have p-1 on friday u seem to be working hard on p-2

 

[Min Thaw]

oh..^^
i don't see much difference in p2 and p1..so i think it would be beneficial for me to solve both of them..
sure..take your time "sis"

 

[Stancy Motha]

it's easy just reflect and enlarge
or enlarge first and then reflect

 

[Stancy Motha]

reflect and enlarge man u don't get that?
reflect abc then enlarge it in different ways till u get the triangle A2B2C2

 

[Min Thaw]

okay tqvm

 

[Stancy Motha]

[Min Thaw]

yeah i got it now..thanks
