I am looking forward to seeing the subject off. My marks in it are like 20% lower then all my others. Need like 45ish for it to count. Still love it though. Worst time for it to be on, last exam on a Friday afternoon. I will use 3-5 historians in depth for section I depending on the...

How did you do 16b? I got something to the power of 16. Everything else of mine basically matches. Btw what do you think you got raw?

Although I have no sources, my guess is that the majority of students that do physics most probably do at least the 2-unit course, and hence have some mathematical ability. Hence the cut-off will probably be higher then normal in my opinion. Personally I liked the paper, it should be like that -...

T(1) and T(2) in the above post are the two expressions. T(1) is the time taken for the bus to go from D to P. T(2) is the time taken for Claire to run from F to P. BTW, this is a 2-unit question as you most probably know.

There is probably a mistake somewhere in here. All times are in minutes. I\ assume\ you\ could\ derive\ these.\\ T_{2}=\frac{25sec\theta}{24} \ \ T_{1}= \frac{40 +5tan\theta }{18}\\ Let\ T = T_{1} -T_{2}\\ \frac{\mathrm{dT} }{\mathrm{d} \theta }=\frac{5sec^2\theta }{6} -\frac{25sec\theta...

I remember doing this one a while back, took me a bit to realise what I had to do. Could you do part i? For part ii you have to differentiate t(bus) -t(girl) and maximise it.

Yes, I got it as my second preference.

That 90+ requirement does not include bonus points though. Realistically, it is not hard to get 5 through the HSC plus program. Similiarly, the academic achivement award, or the Access scheme can add another 5 points. It is probably best to just do the interview, you never know what your ATAR...

Seems to be a pretty dodgy question. Each textbook seems to say differerent things. In a situation like this, reckon the markers would ever except two answers?

That is why I could not do it then, you wrote the question wrong. You wrote 'sin2xtanx' not '2sinxtanx'.

I got 5.something for the constant. I quite liked the questions. The 7-marker was a repeat of past years though, was the same as my trial as well.

I got both my choices: Finance and Marketing.

Well I cannot get it either. I am probably missing something very simple though. Looking at its graph though, and using newtons method, the solutions seem to be not exact i.e. not simple fractions with pi's. You will have to wait until a smarter person comes around.

Na mid 500's. However that rank is grossly exaggerated. Like all but two of the top bands came from one student - our highest uai in like 10 years, the rest were from subjects like Hospitality. This year, judging from the trials, my cohort will most probably get no top-bands. Our rank will...

You did not have to differentiate it. By observation, you should know that sinx always lies between -1 and 1. Hence the minimum height occurs when sinx =-1. Its similar to shm in 3u.

Very doable. 75-76ish/84 at this stage. Did everything except 7ci - guessed the right answer to the last mark. How about you, a rank? I just realised that technically, I think my school will be one of the top school's for maths in the state when the results come out - 100% should get top band in...

I have no idea. Wasn't that hard to be honest. Although I have to admit I have never seen a question like that before, I don't know what the fuss is about. Q10 deserved to be q8-9.

And everyone in this forum is labelling it the hardest 2-unit paper ever.

That's what Shady did, and he is looking at 119.

Although I agree with you to a degree, I doubt anyone on these forums will get 120, although there was last year. If you don't get first in the state, you just made an idiot of yourself.
