As if you wouldn't show it anyway?
Usually I would have and I was going to change it to that except it would have made my page look really messy and hard to follow and I thought since its one mark and they used a different verb it won't matter

it was easier than what I expexted zzzzz anyone can explain the last probability?
Which part?

Hey be careful bro, it was 2^(2n) so you had to multiply by 2^(2n +1)
Sorry I didnt remember the question that well yes that was right.

Did you screw up?

Finally someone who can make me feel better
The people who thought it was easy probably did 4-unit. The people who just did 2-unit and 3-unit would've found it hard - exhibit A and B.

FML.

found it alright hoping for 80% - probability fucked me up the bum and the v^2 graph was a bit of a mindfuck with part iii) trying to find it all - if someone knew the answer to that it would be really cool! thank you!

Agreed... Alot of non extension 2 students couldn't obtain the result required.

Gg its root11/2
why is it root11/2 ? Wasnt the graph v^2 against x?

I'm starting 4u nextweek, would I have done better in the exam knowing 4u?

Hmm, I just let v=0 and solved it that way

Not really.

Not necessarily, but some things in 4-unit can be used to make 3-unit more efficient.

nah, they're referring to the candidature. 4u kids are often more mathematically capable and will do better

##### gone ghost
thank you to those who answered the probability- lost all 4 but hope no where else ))

Maybe. If you're capable of doing 4u (particularly the harder 3u area), then you should be able to tackle those corresponding topics in 3u.
