Maths Ext 2 Predictions (4 Viewers)

what are we thinking for 4u
its been getting harder each year and last years exam was diabolical so im expecting some crazy stuff this year
maybe vector planes probably a calculus inequality proof

thoughts?

a former chief examiner one said that exams should eventually cover all the aspects of the syllabus within the life of the syllabus.

we only have 3 more exams before new syllabus comes into effect, 2024, 2025 and 2026, and i think there may be an aspect not covered well yet, and that is fallacious proofs - like a student did this proof and made mistakes, identify where the mistakes are, or something like that.

so perhaps we may see something like that, if not this year, then 2025 or 2026

Honestly I don't see vector planes, I'm not sure if they're explicitly in syllabus?

this is great thanks

pretty sure they are, i remember them getting taught very shortly though

I feel like 2022 was harder than 2023 imo hopefully a lot of mechanics

There was one of these types of questions in one of the year’s multiple choice but it was very easy

 

[tywebb]

yeah like 2022 hsc Q2 but how about a harder one like the entwistle trial

planes are defo OOS from what I've heard

I reckon 2023-ish difficulty
as long as there's not too much vectors I think it should be alright

Decent chance something will be in there like that since there is always something new, could be in maybe like q14-15 since q11-13 are almost the same every year

Are there any other questions that haven't been tested in topics like Complex Numbers, Vectors, Integrals, Mechanics, etc. ?

Also could hard questions repeat? Like how 16c of the 2021 HSC had a similar question (16c) in the 2023 HSC?

 

[tywebb]

maybe some euler form questions which are not just basic ones, but ones which makes the solution much more efficient than would otherwise be the case, and i don't just mean roots of complex numbers, but perhaps a more scaffolded version of this:


so with eulers's formula we get this



but try without euler's form and it is horrendous

- especially since they are deleting euler's form in new syllabus - might not happen this year since exam was written long before new syllabus came out, but could happen next year or 2026

Wait can you send an example of one of these vector plane questions please?

 

[Sam14113]

Surely geometric or combinatorial mathematical induction

I was hoping for this last year in my HSC and it never came … surely it makes a comeback?

In Cambridge, vector planes are an extension topic. Planes are not mentioned explicitly in the extension 2 Syllabus. Vector planes have been examined in past extension 2 trial exams.

 

[Epsilon2184]

My teacher emailed asking about this to the nesa people, they said the Cambridge textbooks are written with outlines of the syllabus but can go out of it from time to time. An example is the ext1 syllabus having moving objects and needing to use newtons second law which is out of the ext1 syllabus although still tested by some schools internally

ive done this question where is this from

 

[appleali]

so what are the topics likely to come up this year?
