possibly anywhere between 68 and 74 based off the large majority of people finding the exam very difficult but who knows there could be a lot of quiet kids that may have found it easy

he just didnt rationalise the denom?

88 might go to a 96 or 97

also for 12a they went from x to x^2 incorrectly. There should be a plus in front of the y^4 not a minus.

I believe Q8 is B instead of D Also for the volumes Q in 13a they forgot to multiply the height by 2. Should be 2y not y

have to buy the raw marks report AND hsc results check (cant buy them separately) for like $52

Q1-14 were normal but Q16 and end of Q15 were hard hoping for 88-93 raw

question statement was something like 'discoveries are not always new and not always joyful' to what extent... for my prescribed i said the author showed that discoveries CAN be new but NOT always joyful (but rather confronting) for my related i said the author showed that discoveries are NOT...

if they say 'to what extent' are we allowed to agree on some parts of the statement and disagree on other parts of the statement? or does it have to be a full yes or no

im confused. engineering is one of the hardest subjects in the hsc mainly because the syllabus is so broad and they can ask you almost anything, therefore making it hard to score a high raw mark. is this why the aligning is really good?

so why is the aligning for engineering so good but the scaling so bad?

on rawmarks.info it says that for engineering studies in 2013 an 80 aligned to 95. how is this possible considering engineering doesnt have the best scaling (in terms of the difference between aligning and scaling)?

does anyone know the average/top end salary of a fully accredited actuary (FIAA)? because people have told me different numbers than what it says on google.

note the domain of inverse sine is -1 <= x <= 1 if you graph the numerator and the denominator separately you will find that one is always greater than the other and hence the quotient is less than one for all real x. simplifying the LHS inequality gives you x^2 >= 0 which is also true for all...

http://prntscr.com/kkd19x idk if (iv) is right, and there also might be a faster way to do (ii) edit: it's meant to say f'(x) > 0 in (iii)

How do you do part (iii) for this question? Thanks in advance

How are 1 and 2 equivalent? 1: 2: Also, does (1) produce a standing wave? Don't you need two waves of the same frequency interfering while travelling in opposite directions?

How did Hertz measure the speed of radio waves? Different sources say different things however they all said the frequency of the wave was known due to the experimental setup: 1. He allowed radio waves to reach the receiver via two different paths: one direct and one after reflecting off a...
