HAHAHAHAHAHAHA fuck me, 2u kid here, I think I skipped about 12 marks and this is coming from a usual mid-70s/84 rofl. I've never skipped more than 5 marks in any other paper I've done. Got the probability but fucked half of 7b and rates.

I would be so fucking happy. Screwed for random complicated projectiles though.

Okay I suck at these questions, can someone explain to me HSC 1998 6bii)? I don't get the Success One solution (and it doesn't follow the marker's comments for full marks) and the Maths Association one involves testing points and sketching a full on diagram which seems a bit ridiculous to me for...

You don't need a graph or whatever for short answers. You can use it to help you explain what you're talking about (e.g. if you wanted to talk about 'through a shift...' etc.) but I don't think you'd get a mark on a graph alone You could say that through lowered costs there would be more demand...

WANT THIS SO BAD YES failure is imminent

HAHAHA ide

Okay, everything you said is relevant, it's just finding shorter ways to explain things or cutting down on multiple ideas. You could talk about any of these in your essays though. I'll just edit what you've said: MACRO Macroeconomic policies may be used to address cyclical u/e through...

naaaaaaah i worked my butt off in primary school and got so drained for high school

notice f'(6) = -3 therefore m of f(6) = -3 also you know f(0) is at 0 which means f(4) must be at 0 (it's like a downward parabola with maximum/turning point at 2) m = rise/run -3 = x/2 x = -6

yes you can use calculus but it will take longer, and it will give you BOTH the maximum and minimum values: dh/dt = pi/6 x 0.7cos pi/6 t let dh/dt = 0 for turning points pi/6 x 0.7cos pi/6 t = 0 cos pi/6 t = 0 pi/6 t = pi/2, 3pi/2 t = 3, 9 then you have to test them and explain :P

minimum value of sin pi/6 t is -1 (i.e. the minimum for any sin function) therefore min h = 1+ 0.7(-1) = 1 - 0.7 = 0.3 therefore 0.3 = 1 + 0.7sin pi/6 t -0.7 = 0.7 sin pi/6 t sin pi/6 t = -1

Ughhhh I am getting 6/18. Can someone take a look at this and tell me the flaw in my method? Well, two methods (which are virtually the same thing rofl) http://i55.tinypic.com/2eelc3q.jpg http://i51.tinypic.com/2vmyma8.jpg edit: lol i just realised i accidentally wrote the wrong possibilities...

faaaaaaark ru srs. i thought half of 4u was sketching graphs or shit n i hate graphs to the max also tbh i hated the class for 4u (was in the top class for 3u rofl = hated class/teacher/everything) so i probs would've taken my life if i had to go every day (not to mention morning/afternoon...

Favourite: Circle geo, binomial theorem/prob, perms/combs, trig identities Hated: Projectile motion, shm, vel/acc, curve sketching

You need to know everything under the syllabus dotpoints. These are clearly set out under topics so they're relatively easy to go through and understand. They are also all as equally as important as each other, as literally any of them can be tested on. You can find the syllabus here...

well wtf is the 'ply' part supposed to be? like MultiPly? wtf? rofl. what usernames did you try -______- .. like 'Champion', 'Elite', 'Fag' ?

man up, I'm pulling all-nighters just sit down and chill for a while okay? you can't have forgotten everything from trials right? you still have the weekend, calm down.

Wtf? You have to be stupid to go into an exam without knowing a simple formula and risking it all for a formula? Just for the record, someone has actually been caught doing this kind of thing (wtf though)

97 reported mark I was comparing to the 98'er and attempting to suggest that she may have gotten a lower raw mark, but I wouldn't know because texts align differently. She did do p&p/lta + hamlet though :P

idg your username, explain
