Is the 2020 hsc easy in comparison with the others ? Caus thats the only one ive done

Heyo u guys tried the 2024 north Sydney girls paper? It's so wierd lol. Some very 'interesting' proofs, questions requiring worded responses, weirdly very easy but thought provoking stuff scattered around with some interesting methods required to solving questions. Wierd af paper ngl

Yeah it’s easier have a look at the 2022 paper thats abt as hard as it’s been so far imo

how on earth are we supposed to do some inequality proofs
genuinely some of them you just have to pull the method out of your ass
is it worth memorising them? like im legit contemplating it at this point

 

[appleali]

also are we allowed to use am/gm for greater than 2 without proof (unless the question specifically asks to prove it)
because ive seen trials where am/gm for 3/4 is allowed to be used without proof
is this the case for hsc?

No, we cannot quote it. Most of the proofs will be requiring you to prove it for those 3/4 cases. You must also prove the basic case. However, you can reference it in a later question if you need to.

Yep. Its the easiest by a considerable margin

What do you guys think? I think a we may get a harder proj motion question this year maybe q13 or 14.

wasnt q13 c last year an 8 marker projectile motion question? we probably will get one in q14 or 15 i reckon tho

thoughts on calculus/geometric inequality proofs? haven’t seen that in a while

if it does appear then it will probably be some squeeze theorem with riemann squares. usually the questions arent too hard tho

yess my math tutor said that its getting harder each year

By any chance, are you able to post an example of a question like this?

is this worth trying to understand?

tbh it probably wont show up, but given that there was something similar in the math adv hsc (2022 q29) i would just say give the question a go its not too bad

what, istg i do not remember learning anything like that at all. Which topic is this from? I need to check to see it.

its a mix of proof an integration and im pretty sure its in cambridge

Would it fall under this dot point from the syllabus?

nope i believe thats under induction.
it probably falls under this one but idk im not a syllabus slave never looked at this thing before tbh
