    Re: Wow, fuck that yes this was it. it was 7/8 - sqrt17 / 8 which worked out to 0.36

    Re: Wow, fuck that 8 or 8n or something, i can't remember i intergrated from 0 to 2pi/n for the acceleration graph, as the area under an acceleration graph is equal to displacement =/

    General Thoughts: Mathematics Extension 1

    Re: Wow, fuck that hey for question 3(a) did everyone else get that A=0? It made no sense to me, like, why would they say x = Acos(nt) + Bsin(nt) if A = 0? It says it is initially at the origin so at t=0 x=0 which means Acos(0) + Bsin(0) = 0 which turns out A = 0

    Wow, fuck that That was 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. I reckon I'll be lucky to get 80/84. the first part of Q5 took me forever for...

    what do u think?

    Possibly, apparently everyone found this years exam harder? I don't really think so, i got about 110, which i get in every test. So yeah, borderline. I think cutoff is usually mid 70s so if the marks were lower across the board you might squeeze in

    raw marks for 95+ exam score?

    i got 92% in the CSSA trial, would a similar result in the HSC get me above 95?

    yep. answer's all that matters for 1 markers

    Exam mechanics question

    they are, generally, as long as thye can tell you know what you're doing, which is why i'm pretty sure i only lost 1 mark

    Reflection Theory

    PQ was common. they were congruent

    Exam mechanics question

    I ran out of time. I got the 3/2 vt bit and was about to finish the question when they called pens down. So i finished off with a quick 'by inspection, this is equal to whatever'

    How many marks did you lost?

    between 6 and 8 definately. Maybe a couple extra for silly mistakes. oh well, i'll find out soon with the solutions :D edit: although, you never know. In the trials there were 2 or 3 marks I was sure i didn't get and I got them. Usually because my Q8 working relies heavily on wording when I...

    Exam mechanics question

    oh, you're kidding me :D Even last night, i was like, for intergrals you need to remember the shortcuts for semicircles and the last two on the intergrals sheet :(
