LOL I am hoping for Relative Velocity ... Aliens colliding with each other on a screen, how exciting :P

Lolz, that'd be awesome, it's more entertaining than some random boat/plane blowing in the wind ;D
Relative velocity is on my BLACK LIST for now. I'm doing IB Maths HL next year so hopefully, no more of that ;D

I thought the question required us to find the exact value of p instead of log p ?

uhuh! it says P :) :) :) IM SURE!!!!!! cuz all my friends did p as well.... but kinda got different values cuz our gradients were kinda diff

Hey dibbs, what came out for V1?
From what I've been reading it was completely different from V2. Topics I remember:
Lots of calculus!
Binomial exp
Logs
Sets/Venn
Functions
Surds

What about V2?

Kudos for us :D I found p to be 25 sth - 10^1.4 :)

Adrian : You did Variant 1 ?

I will be doing A-Level Mathematics with Further Mathematics next year, and Mathematics is no more than a repetition of what has already been covered in the IGCSE Additional Mathematics syllabus :D

Dibbs : All the topics that you have just mentioned did not appear in the Paper 2 Variant 2 at all :O

Haha what if they're planning to switch variants and papers but just with different numbers? -sigh- If only.

Uh straight line graph in the form Y = mX + c with y^2 = Y and sec x = X

2 x 2 matrix - finding the inverse and hence solve simutaneous equation

etc etc.

Hey dibbs, were the functions and sets tough?

TBH I found the whole paper really easy but the rest of my class had a lot of problems. I'd say that it depends on your ability. Since you've studied, don't stress, it's not tough (:

dont worry darren, u will only need to substitute values given to find the domain. Its rather dogmatic stuff.

By the way I need help to the below:

domain is 2<=x<=7

Find range.
