thank god im not the only one. did like 1hr today. i was sitting in front of my HSC for at least 4 hrs, but spent like 3hrs thinking about random shit sigh

Yea, its a general 'formula' that u can use

If you still dont understand a particular concept by now. i would reccommend that u should just memorise how its done rather than learning the entire concept. its far too late to still be learning. rote learn ftw

guessing, but this should be right ^ those lines should be straight. at the 50% mark go up to the line of inequality and rule to the left side. It should look like either 35% or 15% (from the answers) but since its lower than than the 25% mark then it has to be 15%

seriously; mod z = sqrt(x^2 + y^2) arg z = arctan(y/x) write in cis form is that really that long?

Didnt krnofdrg answer it? How does the multiplier affect eco activity? isnt it just govt spending? An initial spending by the government will result in a direct, more than proportional increase in spending. Due to the multiplier theory by Keynes or w/e. Economic activity increases when spending...

irrelevant but; would an ext 2 maths student be almost guaranteed to get a state rank in general maths?

Neoliberals argue that monetary policy does not actually create economic growth but only moves it forward in the economic cycle. Explain

- environmental polices are unpolitically friendly. ie; carbon taxing - govts care about votes and thus would never attempt to jeopradise the current generation for other generations - environmental policies cause structural change. govts are only in for the short-term, thus unpopular -...

Explain the effects of Julia Gillard's carbon tax pricing scheme on the distribution of income and wealth.

Alright, i learnt how write even uglier and even faster than before: (are these still acceptable/legible?) 73 words/108 seconds = 42wpm ceteris paribus 1637 words in 40mins And. even even more uglier: 73 words/96 seconds = 45wpm ceteris paribus 1800 words in 40mins

Wait. what? 'Official' is only in Year 10 and he got 49 for ext 1 maths already. ARE U SERIOUS? I might as well quit life now. Im in year 12 and i probably wont get 49

lolololol ^^ thats exactly what i did. i just randomly guessed that method and it worked. anyone else reckon last year's paper was pretty hard/lame/stupid compared to other years

Where did u get this from? and what happens if there aren't 10%+ markers?

Yeah, the handwriting of some (most) responses were absolute horrid. I typed the ones with my texts up on the computer, just so I could print them off and actually read them properly, and maybe steal some good ideas. Honestly, I think the Board only prints off Band 5 answers, because those...

is this acceptable? its the quickest i can write. thats 38 words and i did it in 1min and 3secs. If i take 38words a min then thats 1520 words in 40mins. Deduct, planning/thinking time, i could probably get 1300 with this handwriting. So do u reckon i should write like this or write a little...

Oh did the marking criteria say both A and D? I saw A only.

yeah i got b through process of elimination. but can u explain why an increase in capital expenditure would lower unemployment? is like what bobbo said? capital expenditure = expansionary fiscal stance

^ thanks for that. big sigh of relief that the hsc markers do it as well. they dont even right "by comparing real and imaginary parts..." or "by inspection..." they're really lazy they only did like, 2 lines of working for a 3 mark question. (disregard 1st line and last line since its not any...

Find the two square roots of −16 + 30i. obviously the most popular method of doing this is by solving it with simultaneous equations, but that takes WAY longer. I can probably do this in 30secs with inspection method and probably takes like 2mins with simultaneous. This is from Sydney...
