Don't worry- state rank 4U next year. Honestly, if you're as good at 4U next year as you are at 3U this year- you'll get that state rank fairly comfortably imo

This. You've got a decent shot at 100 HSC- obviously assuming you get 100 external (which you will)

First will be moderated to 100. Your internal though won't be 98 unless your decently far from 1st. I don't know how far you are but if you're like 1% off them, then you'd probs end up with an internal of just above 99, giving you HSC mark of 100.

Kilometrico FTW

Just did the Q16- that was very nice. What people said before was quite right imo- it not impossibly hard but it looks very intimidating haha.

If that will honestly give you a sense of achievement then go for it. You'd be lying but hey- if you determine your sense of worth based on whether you got 93.4 or 94, then yeah- whatever you want

I still don't get why we are having this discussion. It takes the same amount of effort to bring a pencil or a pen into the exam. Just use a black pen that doesn't smudge.

Yes this is true but I'm going to be politically incorrect in a sense and say that this is BS. Yes you can get 99.95 with the most random subject combination. No one will ever do it though- the simple reason being that if you want .95 with gen maths, drama, society and culture, textiles and...

Yeah, I derived it though. Basically the equation of the tangent will have the form y=mx+k. Sub this into the hyperbola and you end up with a quadratic in x. Now by letting the quadratic=0 (for tangent), you can find a value for k in terms of m,a,b (that thingo under the square root) and then...

Haha effffff. I flicked to the very last part of Q16 just in case there was one of those limits questions or something that you could just read off but obviously there wasn't. If we had noticed those questions though...

Really? Maybe it is and we all just ran out of time- I'll take a proper look tomorrow. Personally, I could only get a and b) i) 2,3 by assuming the result we had to prove in 1. Everything else though...

Is it actually doable? I'm still intimidated...

A cube is a rectangular prism- specifically a rectangular prism where all the side lengths are equal. Its like a square is still a rectangle

HD- lol go Team BOS

There's a few ways. This is how I did it. Note that 4a+4b+4c=4 ->a+b+c=1 Now the largest surface area will come from where all the side lengths are equal (you can prove this but not neccessary for MC). Therefore a=b=c=1/3 Now A=6a^2 =6/9= 2/3

Yeah I know- I didn't think of that in the moment though :( Though were you there when I outlined my solution to finding A(x) and B(x) for Q11? I think that is the most unco solution anyone did in the whole paper. Though I made up for it by getting the whole of Q14 pretty quickly which was good :)

The other roots were not real apparently- I got that one wrong. Lol I got the four unreal roots and I figured it was too much effort for one mark to check the other two :(

Ok guys what were your favourite questions in the paper? Personally, I really liked the prove a+b=c (the tangent question), Q14b (the roots of z^n=1), the whole of Q15 and all those ones about explaining the geometric significance of the result proven. I think I would have like Q16 if I could...

Nah, I think my solution was WAY superior to this :p I still can't believe my method when this is so simple lol

He made them which is why its extra impressive. I reckon BOS should throw a party for Carrot at the end of the year (srs)
