    Hidden unemployment question?

    this is the short answer one right? I basically just wrote the definitions of hidden u/e and u/e and then explained why it won't be reflected in the u/e rate using those definitions

    General Thoughts: Economics

    I put B but idk if thats right or not.. my idea was that flooding in ag areas would sharply cut off supply so would be a really big one-off increase and thus increase headline a lot, and that increasing micro reform is like how growth through shifting supply curve is noninflationary (leading to...

    okay i put all the same ones i think, except for q7 where i had double contractionary at first and then changed it to expansionary fiscal fk

    General Thoughts: Economics

    fk i think my mind mustve exploded on q14, I realise now I picked something entirely wrong 5 was about foreign aid (capital or net secondary??) 6 was about increasing efficiency of domestic industries to improve international competitiveness - increase/decrease import quota and subsidies 7 was...

    Q25 "Discuss the continuing role of microeconomic reform in achieving Australia's economic objectives." Q26 "Analyse the changing sources of economic growth and their effects on the Australian economy." Q27 "Discuss the contributions of international organisations and trade agreements to global...

    General Thoughts: Economics

    omg the multiple choice was so difficult for me wtf. Or maybe I'm just retarded or something. Anyone care to tell me what you selected for these questions? 1, 5, 6, 7, 8, 12, 14

    General Thoughts: English Paper 1 (AOS)

    First English exam that I actually managed to finish on time! S1 was alright; just kinda skim-read the texts to save time. S2 was fairly adaptable for mine - I used the image with the guy holding his forehead, and the book thing just happened to be in my creative as part of the story (would it...

    Pens stop writing very quickly

    Right-handed, but I've been told that I hold my pen similarly to a left-hander before (I think in the sense that the right side of my hand "leans" against the paper when I write - like a left-hander but opposite I guess?) Tried most of these methods too but the same shit happens :( . I'll try...

    Pens stop writing very quickly

    Tried that before, just tried it again. The pen writes for like a minute again, then it stops writing.

    Pens stop writing very quickly

    Yeah, that's what I had to do for my trials. I got so sick of the pens running out that I just brought with me an unused pack of 20 pens. Yep. They write for like one sentence, then it rapidly fades out and stops writing. All of them behave like this. Maybe it's something to do with the way I...

    Pens stop writing very quickly

    I press down somewhat hard when I write, but even when I hold the pen lightly and write they still tend to stop writing. Should've clarified - the issue is NOT that the ink runs out. Every single one of these pens that stop writing - when I open them up I find a cartridge full of ink.

    Pens stop writing very quickly

    Anyone else have this problem? And I mean VERY quickly - my pens stop working after like 3-4 pages, sometimes less. I've tried all different sorts of pens too (well, except fountain pens since those are expensive). Used all different brands and models of pens - Papermate Kilometrico, Papermate...

    HSC 2015 MX2 Integration Marathon (archive)

    Re: MX2 2015 Integration Marathon Should look like this: Did this by dividing through b^4 tan^4x and then splitting the numerator into two fractions. Then substituting u^(1/3) = (a/b)tanx and w=(a/b)tanx. Then it simplifies into algebraic integrals like 1/(w^4+1) which can be evaluated using...

    HSC 2015 MX2 Integration Marathon (archive)

    Re: MX2 2015 Integration Marathon Urgh that was horrible. Maybe I did it in some inefficient way but when I went to verify my answer with wolfram.... it gave me this gigantic expression with complex numbers... Here's what I got: I did this by expanding the sin(4x) thing and factorising the...

    HSC 2015 MX2 Integration Marathon (archive)

    Re: MX2 2015 Integration Marathon Split an x^2 off the numerator into two fractions, then use reverse chain rule on the first while the second one factors into a perfect square on the denominator to get a ln expression. Should be something like (2/3)sqrt(x^6+14x^3+66) +...

    2015ers Chit-Chat Thread

    this is what happens when your english head teacher's idea of "feedback" entails a bunch of pictures of dogs on a powerpoint slide, and when their idea of teaching is just "oh guys here's some notes i copied from the first link on google about metropolis, have a read"

    iirc it was like 99 for rank 1, 96 for rank 2, 95 for rank 4, 94 for rank 8, 93 for rank 10 (cohort of like 50 people) and idk after that. Everyone scored really highly in this exam me too :(

    Quick complex numbers problem

    In part (iii) you find a=1 and b=2 (or at least that's what I got), so then you use the quadratic x^2+x+2=0 and solve it for the roots alpha and beta. Then you equate the imaginary parts so you can get that sin expression thing.

    HSC 2015 MX2 Integration Marathon (archive)

    Re: MX2 2015 Integration Marathon We get this horrid thing: By rewriting it as 3u^3/(u^6+1) where u^3=tanx, and then decomposing it into a giant partial fraction of quadratic factors.
