Re: Wow, fuck that

Did you get something under root 17?

yes which i remember went to 0.36

also fucking exponential decay... i got so nervous i had negative time i just took out the minus sign lol

Re: Wow, fuck that

im pretty sure its 4 because if u sub the time in the velocity it would give 2. but at t= 2pi / n x=0 therefore its 0-2-0= travels 4 units. IDKKKKKKK

i just did it again, i got 8 FUUUUUUUUUUUUUUUUUUUUUUUUUUUU
Left out a 2 from B = 2 in the first part of the inegration and got 2 + 4 instead of 4 + 4 FUUUUUUUUU

Did you still subtract it from 10am

no . I just thought i must have been wrong. What was the value of the time?

mate. I can't believe it did that.

Re: Wow, fuck that

was the time 8:46am for the cooling question.

IMO, test was not hard, just too much.

Re: Wow, fuck that

That was fucking hard man. I usually get 82-81/84 pretty easy in all the past papers i've done, and finished with more than half an hour left

today i was working literally right up until they said pens down.

Me too... T___T Today's paper was unbelievably hard.

That park q tripped me out cos I thought you couldn't have negative time :'(
Damn, should've just added what I got to 10am, could've gotten that mark easily. *Sigh*

im still stressing about this q
hopefully it was 8.46 am though. that seems to be the general consensus

A=0 :O WTF man, I didn't realise sin0=0 for the x(t) but I did for the v(t) equation???? Alright, one careless mark gone, please give me carry forward error!

Re: Wow, fuck that

ok..so how do u do the 2nd part of the rates questions? o.o

yeah, not enough time to actually think about the question.
I was thinking more about finishing, and that's pretty distracting...

 

[UnrealAnchovies]

what was the e4 cut off for last year's paper chaps?

 

[roryclifford]

Ah some questions were different (weird) and the test was really long, thus was hard.

Well relatively harder than past papers from the last few years, same time problems as 2006, just not quite as hard.

Maths is over though! Until engineering yewyew

It was negative value like you meant to subtract 1 hour 14 minutes from 10am..I added it cause I thought negative was not right...sigh

Re: Wow, fuck that

what did you guys get for p? i got some ugly fraction

I was getting a complex number so skipped it haha

 

[Wight]

Re: Wow, fuck that

Pretty hard exam, really needed an extra 10 or so minutes and I would've finished... made some really stupid mistakes (as always), such as getting the value of B as n :S (gonna see how the fuck I did that). Will probably get in the 70's/84...sigh.

Just realised I fucked up a graph...welp, 60's out of 84 for me -.- fml.

 

[Miim93]

I really bombed out in this exam, I started stressing and I ran out of time and missed over 15 marks :| .. but my friend last year got 72% raw and ended up with an HSC mark of 91%.. I'm not sure how that works. I'm ranked well.. Does anyone think it's still possible to get a band 6 :S? *trying to stay optimistic while crying in the corner*

Re: Wow, fuck that

part (ii).

I thought it was just dV/dt = dl/dt x dV/dl
