This looks really bad out of context (PS: look up a South Park episode called "T.M.I")

Yeah I organised a BBQ last year. Was great to meet a lot of people on person (including jimmy)! We used to do BoS meetups more frequently in pre-covid years. Happy to organise something if enough people are keen to meet up post-HSC.

Boom! Business Studies results and the marking criteria/sample answers are attached below! :) Thank you to everyone who attended to the event and attempted the paper. Congrats to the top student who scored 88 in the paper! Thanks heaps to @jimmysmith560 for helping to write the paper and...

Let me be very clear here. This forum obviously has a lot of unpopular opinions and we have no issues with having diversity of opinions. I could not care less which side of the argument you are on. You all have your own personal biases and this is very obvious when viewed by an outsider (whether...

It depends on whether we (still) have people who are prepared to write and mark them. These events are supported by large volunteer efforts. As long as that is sustained and there is student demand for it then we can keep this going in future years.

💥 Here are the solutions and marks for the 2023 Mathematics Extension 1 BoS trials! Similar to Mathematics Extension 2, please note that the question paper has been updated (which the solutions are aligned to) with some minor adjustments to a few questions (e.g. split into parts, fixed the...

I think it is unwise to assume there is such thing as an absolute truth. These should always be seen as a piece of evidence based on what we know today to support a theory. New information may come about that supports another theory and this is simply the scientific process in action (think...

Well for starters, you have to consume media/news from somewhere? Or would you prefer to live in a bubble where everyone is sunshine, lollypops and rainbows? Or worse, consume media that is only appealing to your existing beliefs/biases (e.g. from social media) and not something more balanced...

Almost ready to go. Is there any particular question(s), you want an answer for right now?

Definitely. Check the syllabus under Polynomials, there is a dot point that explicitly mentions quartics. As to why it’s not on the formula sheet, who knows… there are a lot important formulas missing in that sheet that should be on there (not to mention some of the ones already on there are...

I think you have a different interpretation of “original” to mine. Like, with your interpretation I could argue the reduction formula Q15a)ii) was “original” because that technique isn’t a standard thing you find in that context and it makes you think. But I doubt many people would call that...

lol look up any question (trial, textbook, internet) related to equilateral triangles and complex numbers and you’ll find similar questions. It’s a pretty well known result. (PS: some version even appeared in past BoS trials). I don’t think we should expect “originality” when it comes to Maths...

When you handle the double angle with a substitution your limits would change from 0 to pi. However, note that integrating a sine function (and subsequently it’s powers) from 0 to pi is the same as twice that from 0 to pi/2 by symmetry (see the graph). You can show this algebraically but that’s...

That’s probably because ‘cis’ is not a standard or commonly used notation in mathematics. It is rarely seen outside the HSC. Everyone else just uses the exponential form (note that “exp( )” is standard notation) or the full mod-arg form. I don’t think I’ve ever seen ‘cis’ used in uni maths.

Tbh, I don’t see the point of using the short-hand ‘cis’ when the exponential form is just as convenient (and technically shorter)

Guys please keep the debate about the ideas, not the person. Personal attacks are not acceptable.

......and here are the results and solutions for the 2023 Mathematics Extension 2 BoS Trials! 🔥 🔥🔥 Please also note that the question paper has been updated (which these solutions are aligned to) with some minor adjustments to a few questions (e.g. edited some wordings and mark allocations)...

lol result is known before WA polls closed
