Here are more details from new senior maths:

That was motion in a line. Much easier to do with resistance proportional to square of velocity. What I am talking about is projectile motion with resistance proportional to the square of the velocity. That's totally different and much harder to do - even when compromises are made such as the...

Well Cambridge don't just not do it. They also say why they don't do it. Here is what they say about it (on page 257): "There are also some questions involving projectile motion with air resistance, however, these are very limited as solutions can only be found in one case, when the resistance...

The syllabus is unclear as to whether this is required. Even some textbook authors have contacted NESA to gain clarity on this issue to no avail. Some texts include it. Some don't. In particular, Cambridge and Terry Lee don't. New Senior Maths and Maths in Focus do. You may be wasting your...

So I got the new Ext. 1 and Ext. 2 maths in focus Year 12 ebooks - both suffering from font corruption. The font corruption is extremely bad in particular in the Ext. 2 ebook. Similar font corruption occurred in the early versions of some of the cambridge ebooks. Maybe leave it for a few...

Indeed that is true for Ext. 2. However I think they are the first to put up trials for the new syllabus. They have 2 from 2019 for Standard 2, namely Manly and Sydney Grammar. Whilst that may not help current Ext. 2 students very much, it does help those (such as myself) trying to find...

Unfortunately the Ext 1 ebook which was due today is now delayed another week. Here is a revised version of these dates released today by cengage: Ext. 1: Oct. 24 Ext. 2: Oct 24 Advanced: Nov. 8

There are still some left on the"new thsc" website (zaxu version, not github): https://thsc.zaxu.tk/Year%2012/Trial/Science%20-%20New%20Syllabus%20%28post%202018%29/Chemistry/ There were a lot more there before Oct 10, but some got deleted due to copyright.

There has been some confusion pertaining the ebook availability for maths in focus for Year 12. Some of the books have been released when the ebooks are not ready. Today Cengage have released information pertaining to the availabilty of the ebooks. First it should be said that all the year 11...

Might be close though. Apparently the Ext 1 cambridge yr12 was published yesterday. At least it should be a lot better than when year 11 Ext 1 had to wait several weeks after the course had already started for the cambridge book.

Apparently the Cambridge Ext. 2 is available for purchase now. Not sure when they will be delivered though. I suspect the maths in focus will get delivered before cambridge. Hopefully both will be delivered before term 4 starts. For ext 1, not at all confident that the cambridge will be...

What happened to your website https://www.masteringhscmathematics.com.au as advertised on each book? I've seen your real site before with solutions etc. But sometimes when I click on it it sends me to a page which seems to have been taken over by "Australian Building Management Group". Their...

Indeed they did change again. Maths in Focus Ext 2 was going to be Sept. 30, but now it is today. So now the file http://users.tpg.com.au/nanahcub/texts.pdf lists maths in focus publication date as Oct. 4.

For 2u/3u/4u there is Cambridge, Maths in Focus and New Senior Mathematics which come with ebooks. Some of these have not been released yet but should be out soon. For 2u/3u there is also harder hsc maths which come as ebooks only (but you can print them if you want to). It is not clear if they...

I suspect that the main reason the calculators were reinstated was because year 11 students had already bought them. Now that NESA will in future give 2 years notice for any changes, there is a danger that they will in fact be banned yet again. They were banned in the first place because NESA...

It has been said before that publication dates are in a state of flux. But some of the predicted publication dates have quite significantly changed. So the list at http://users.tpg.com.au/nanahcub/texts.pdf has now been updated - as best as I can do so far. This may well change again in the...

Now that NESA have reversed their decision to ban the calculators, they may now provide tables and relax their insistence on trapezoidal rule. This is because not every student will have the CASIO fx 100AU or 100AU PLUS. In fact most approved calculators don't have normal distribution...

Normally you need an even number of gears in a loop for them to work - unless it is in a Möbius band shape. Someone made a 3D printed Möbius band shaped loop of 15 gears - that actually works! Here is a video of an odd number of gears working in an intertwined Möbius band:

NESA has backed down. The new list is at https://educationstandards.nsw.edu.au/wps/portal/nesa/11-12/hsc/rules-and-processes/approved-calculators/calculators-for-the-2020-2021-hsc and includes the CASIO 100 AU and 100 AU PLUS.

The Cambridge Extension 2 book is now due to be out in October. But the page proofs are available now in Cambridge's website at: https://www.cambridge.edu.au/education/titles/CambridgeMATHS-Stage-6-Mathematics-Extension-2-Year-12-print-and-interactive-textbook-powered-by-Cambridge-HOTmaths/...
