i made a slightly easier one good?

13aii said or otherwise here otherwise method using cross product good?

they don't but people want to know how they went as soon as they finish the exam. so some try to get solutions out within a few hours so people don't have to wait for nesa solution it is also good, especially in extension 2 to get multiple solutions from various sources to see all the...

solutions are in post #290 from there 29b sol is:

cognito recently became the first with solutions to the chemistry and physics papers, and they missed the boat with maths as far as being first is concerned but nevertheless apparently they are coming out with solutions to ext.1 and 2 eventually, but don't know when they have placeholders for...

here is cleaner copy of paper

i added a pdf of the cognito solution into post #290

the cognito also agrees with the starboy/jeff>>=/beyondtutoring answer for mc

another sol: https://www.cognitotuition.com/blog/2024-hsc-physics-exam-paper-exemplar-answers-solutions this one for rest of paper too attached as pdf

well beyondtutoring tiktok agrees with them https://www.tiktok.com/@beyondtutoringau/video/7434387170330234132 i attached a zipped mp4

my confidence is growing for this because i got other answers from another bro which is exactly the same as starboys this from jeff >>=

here is explanation for 15

dunno if rest of starboy's is right though, better check

starboy answer is D also the 2020 q19 answer is C so i don't think the 2024 q15 can be C some bros were sayin they the same so has to be C but they not the same so not C

they look similar but are different

starboy's mcq answer: CBCDACBBBCDBABDACDCC so 17, 19, 20 are all C according to starboy

paper

another way to understand this is the position of the asymptote so for y=lnx asymptote is x=0 translate to left by π and asymptote is x=-π then dilate horizontally by factor 3 and asymptote is x=-3π and the only one with that asymptote is A

it would be D if it were the other way around like this dilate horizontally by factor 3 first, so replace x with x/3, then it is y=ln(x/3) THEN translate left by π, so replace x with x+π and it is y=ln((x+π)/3) i sometimes disagree with mathgpt but in this case it is correct
