and now this mg from nesa: https://educationstandards.nsw.edu.au/wps/wcm/connect/f8f0c52a-4329-4b8b-b330-4a9ea336d452/2023-hsc-physics-mg.pdf?MOD=AJPERES&CACHEID=ROOTWORKSPACE-f8f0c52a-4329-4b8b-b330-4a9ea336d452-oLRjsR6

Yeah 1988 Q8b part iv

I reproduced in latex the calculations for q34 faithfully to the handwritten one - regardless of mistakes and/or skipped steps. I checked them with a calculator with values of G and ME as presented in the HSC exam data sheet and they seem to be correct. But do you think it could be improved...

so now joining it to eddie's we have a latexed version for the whole paper

It's a bit hard to read isn't it. So here is a latexed version of the q33 and 34 from this one.

And here is another solution. This one also includes solutions to the q33 and 34

dymocks standard 2 solutions: https://www.dymockstutoring.edu.au/hsc-2023-maths-standard-2/ It used to be the case that dymocks only did the advanced paper. This is the first time they did the standard 2 paper too.

I put one in post #444

The new draft syllabus at https://www.nsw.gov.au/sites/default/files/2023-10/Mathematics-Extension-2-11-12-Draft-Syllabus-for-HYS-October-December-2023.PDF makes it clear that projectile motion with quadratic drag is NOT in the new syllabus. It's just a draft so this may change. But it would be...

At least they are bringing in notation for "and": \land and "or": \lor 3D vectors in Extension 1 - so extension 1 textbooks will have to have a major update to their vectors chapters. Much talk about skew lines in ext 2 - BUT still no cross product - hence one of the most basic questions about...

Have a close look at the bottom of page 18 in the extension 2 Look familiar? One thing you may have noticed in the 2023 ext 2 hsc Q15b was that the line segments joining midpoints intersected in the same point. Coincidence? Not likely! 😈

OK. Media release for new draft syllabuses: https://www.nsw.gov.au/education-and-training/nesa/news/all/hsc-english-and-mathematics-syllabuses-released-for-feedback and from this we see "syllabuses will be released in 2024 and taught from 2026" which means the first HSC exams for the new...

They also seem to have changed 12e 2023_HSC_MATHS_EXT1_HSC_Solutions_MATRIX-EDUCATION.pdf had 2023_MATHS_EXT1_HSC_Solutions_HSC-MATHS-EXTENSION-1-SOLUTIONS.pdf has Also in 13b 2023_HSC_MATHS_EXT1_HSC_Solutions_MATRIX-EDUCATION.pdf had and...

looks like they changed the filename from 2023_HSC_MATHS_EXT1_HSC_Solutions_MATRIX-EDUCATION.pdf to 2023_MATHS_EXT1_HSC_Solutions_HSC-MATHS-EXTENSION-1-SOLUTIONS.pdf I fixed the link in post #451

No The mgs for standard and advanced were published on the nesa website and subsequently removed. Many days later they went back up with updated versions. It seems the ext. 1 mg could do with an update, given the errors which have so far been found.

Oh dear. I haven't had a close look at the rest of it. But if there are so many errors in just 1 question it makes me wonder what else is wrong with it. Heaven forbid if students actually lost marks due to errors in the mg. Could we see it pulled like they did with Standard and Advanced?

Some of their notation is wrong, like they should have arrows for vectors instead of lines.

Here are nesa's solution: from the mg at https://educationstandards.nsw.edu.au/wps/portal/nesa/resource-finder/hsc-exam-papers/2023/mathematics-extension-1-2023-hsc-exam-pack+++++++++++++++++++++++++++++++++++++
