sucks that you guys are a day later than the science guys, looks like some of your favourite tute times are gone :(

gonna learn some japanese brah

maybe.., and yeah i forgot haha.

One example in my 3U paper,I had to prove something using the perpendicular distance formula, then i got something like |x^2+x+1| = x^2+x+1 I lost a mark for that as i didn't prove that it's a positive definite i.e x^2+x+1 > 0

30 is 4U BOS trial last year = 94 HSC :D

So Enrolment is open for the science guys today as far as i know...... now I'm not sure what to pick for my 4th course

It's time

12 minutes left

lol the 4U paper had more probability question than 3U in 2013

not sure if snaking or you're just delusional

excited for it to end?

Lol a similar situation like this happened last year... all fake guys dont fal for the troll

also remember When you sqrt a value between 0 and 1 it makes it bigger, While sqrting a value over 1 makes it smaller ofc sqrting 1 is still 1 There are MC questions that has those comparisons

if i was a newbie i'd be confused at that lol

Re: MX2 Integration Marathon Haha that's alright, that's a pretty neat approach though.

Re: MX2 Integration Marathon But f(x) = 1/(x^2+x+1) is decreasing between 0≤x≤1, so wouldn't B actually be the upper rectangles?

Re: MX2 Integration Marathon The series generates smaller values ... so B?

just pretty much organise a hangout with my HS friends at uni breaks for me

Re: HSC 2014 4U Marathon a\leq ar+ar^2 \ AND \ ar^2\leq ar+a \Rightarrow \frac{-1+\sqrt{5}}{2}\leq r \leq \frac{1+\sqrt{5}}{2}
