Maths Ext 2 Predictions (15 Viewers)

how did everyone do question 16 a - was it vector (a,b) dotted to vector (1, -ksinka) = 0 then some parametric equation?

 

[Allan Mekisic]

If i remember right i got D C A B D A C A B for the first 9. Not sure about q10 but i think i put B

 

[Allan Mekisic]

I got all 10 same as you. Not sure if that’s good or bad.

They were perpendicular so m1 x m2 = -1

i got 10 as B anyone else?

a=i b=j c=i is a counterexample im pre sure as the angle of a+b+c is smaller

 

[lotsoflots]

a=i b=j c=i is a counterexample im pre sure as the angle of a+b+c is smaller

Yep. So must be D

Yes

i found this exam harder than 2023 imo but evr1 says otherwise

Here are my ext 2 solutions. There are probably some mistakes - help weed them out

OPEN CIRCLE ON 11f FS
would i lose a mark fuck

Same, i find the 2023 paper ok but i think i flop this 2024 one so bad

92 to 93

I think it's a novelty thing
like I got way higher than what I think I got today on essentially all my past papers. While I do think today's paper was harder than most of the papers I've done, compared to HSC 2023, I doubt it's harder. I found 2022 HSC kinda easy tho but the general consensus seems to be 2024 is easier.

13 ii - p should be 2

I think 13ciii is incorrect or I may be retarded

Would it be 1 open circle or 3 open circles? I put 3 but now I realise it could be 1

The big difference with today’s paper was the vector questions were all reasonable. Vectors are my worst topic but today’s vector questions were ok compared to 2023 where they were an absolute nightmare. Look at last years question 15. Hardest question in the new syllabus.

I just had 1 on i cause z can’t equal i otherwise the arg becomes arg(0)

Look at question 14 2022. Also a nightmare.
