Maths Extension 2 Predictions/Thoughts (4 Viewers)

With all considered, probably the easiest q16 in quite a while.

for 16a), instead of using mok's method which seems like the right one, I assumed that the centres of the triangles was the origin, and just worked with c = (e^(i2π/3))b and a = (e^(-i2π/3))b. How many marks do u guys think i would lose given ii) is 2 marks and iii) is 3 marks?

assume you got 3/5

You’ve got to be kidding

 

[scaryshark09]

Skill issue. Keep in mind I have the privilege of doing it at home outside of exam conditions. Everyone underperforms in their extension 2 exam.

were u unable to prove the x>ln(x) and the roots of unity? That's tuff.

i swear i overperformed in all my internals, and then it comes to the main exam that counts the most, and i majorly underperform. im looking at 70 raw.

70 raw will get you 92-93 which is 99.95 territory. You did well.

i doubt that. i think 2021 alignment probs, so it will be like 90 which is kinda bad

not really.

what is your constant obsession with always saying that alignment is lower no matter what paper

Bruh I just had a look at the paper if you went Kurt you would have seen q15 ans if you went du you would have seen q16A before. Original questions where?

fucks sake I wish I had this exam seen all the hard questions before

 

[scaryshark09]

idk people were saying the same thing last year with my adv math and engo hsc exams for 2022
like they were saying alignment would be high and everything, and turns out i was pretty accurate.
i was saying maginally better than 2019 alignment for 2022 hsc and it turns out i was pretty close.

you got 97 what are you on about

 

[dumNerd]

wdym. did nesa just recycle questions??

no not the exact same question but the exact same quesiton type. I nearly didn't pay attention to the parametric vector shit when kurt was showing this kinda q cos he said it was unlikely to come lol

on this note actually seeing how good kurt and du is you should buy their resources!

wait for that did we need to consider 0<x<1
