Umm... The locus of z if |z| = 1? Ask yourself "What [complex] values satisfy |z| = 1?". The answer is of course the unit circle. Since the question is obviously dealing with the complex plane, the locus will be all complex numbers which satisfy |z| = 1. If the question is asking about points...

7 b) ii) Note that f(sqrt[3]/3) = A(sqrt[3]/9)-A(sqrt[3]/3)+1 = -A(2sqrt[3]/9)+1. When A < 3sqrt[3]/2, -A(2sqrt[3]/9)+1 > 0. Also note that f(-sqrt[3]/3) = A(-sqrt[3]/9)-A(-sqrt[3]/3)+1 = A(2sqrt[3]/9)+1. When A > 0, A(2sqrt[3]/9)+1 > 0 Then you can draw a diagram or give an explanation...

Most kiddos don't know about this site, as like some people said it's aimed mainly at HSC candidates. Until there are resources and whatnot avaliable this site will probably remain not that popular for year 10 students.

wif sum of u ppl talkin lik i am atm is no wonder u went bad at english ;)

I rung up 3 times altogether. Once for religion and twice for english. The first english and the religion were both great, with them helping me extensively. For english, the discussion lasted 3/4 of an hour. The second english phone call, they put me through to someone who hadn't studied that...

Maths is fun, and I'm a maths type person as opposed to a language person.

Supra, Cleopatra, what schools you from?

Hopefully I'll be going to uni, but after some of those exams... oh dear god

for a compulsory 1 unit class we had quite a lot of people stay.. nearly half. Physics saw only 4 by the end though out of 25ish...

1b 2d... 3b 4d 5c 6b 7d 8c 9a... 10b...

I just talked about the dreaming spirits, and the time of creation.. hopefully a 1 out of 2

Gopo, this is exam thoughts, for people that did the exam. You want to go here: http://www.boredofstudies.org/community/forumdisplay.php?f=38

Is anyone else in the same bucket as me, who barely studied a 2nd catagory, and thus since had only studied in depth rite of passage, is not fucked beyond any reasonable words? There goes literally 20 marks, so even if I get FULL marks in the rest, all I can get is 30/50....

http://www.boredofstudies.org/community/showthread.php?t=45837&page=1&pp=30 I posted that a while back, might be relevant, though probably not.

worst fucking exam of my life. I'm HOPING for over 40%, it was terrible, I hated the questions, nearly all of them were beyond stupid. EVERYTHING I hate about 3 unit was in here, everything I find easy they forgot to include.

I HATE binomial theorem, SHM and projectiles so there goes nearly 1/3 of the marks anyway... the test was so stupid, where the hell was the hard probability, inverse, graph sketching, harder integration etc etc etc etc etc??

I've failed.. so badly.. I hope I got over 1/3 of them right actually, then I'll be moderately lucky... that was the worst exam, of my life. I had a fucking headache and a cold I was trying to hold in. Worst Exam Ever

Ah I finally get it.. I like doing it by inspection, makes more sense to me than a formula, but I'll state the formula as well, in case I get inspection wrong. Thanks everyone

so if the ratio is 1:2 external its always on the A side? This has always confused me.. and now at nearly 11pm the night before I'm about to find out :)

wow.. so many people hate probability and c n p I still say projectiles, SHM, and PARAMETRIC EQUATIONS are the worst
