Well this thread was a nice read...... what do you guys think about the shit that's been going on in Melbourne now? We all know that NSW will be opening up from next month, since it basically has to. This will increase the hospitalisations in the short term at least (With the majority being the...

Bruh I'm sad that railgun and few other animes have been delayed. Yeah I can't be bothered with Seven deadly sins for some reason.

Asking the real questions mate. Then again, I'm wondering how the new light rail line to anzac parade is going to change things.

Another thing about recorded lectures, some lectures tend to use project screen in conjunction with the white/blackboard. For example in my math lectures, there would be one projector used to show the lecture notes and the blackboard to show some examples. However, the recording would only show...

Doesn't seem to have the feature where it converts your handwriting into text Have you ever tried using onenote?

You know a good app that carters writing up math equations by hand?

Hello, so I'm thinking about doing online tutoring since it's basically more convenient, but I just need a good idea of to use. So I plan to use Skype to communicate, but what tools would you guys use in order to show different workings through screen-share? Especially with writing out...

You are the part unluckiest cohort for this reason, no past materials to practice with since you're studying under the new syllabus. My best advice is that you should ask your teachers for some exam materials to learn from.

This is why you shouldn't look at math at 1am lel.. Yeah you're right cause I was thinking of a counter example where you could have you roots \alpha < a< c But your idea would negate that.

Yeah I was pretty annoyed with the amount of silly mistakes I made in my 3U exam (recalled reading back the paper the moment I walked out and thought HOW DID I MISS THAT?) , when I thought I could have gotten a state rank, then again there were heaps who would have felt the same. Whilst I...

So you actually would also have to include the fact that f'(x) >0, \forall x > \frac{2k}{3} Which then you know the function is increasing for between the 3 values

You can't justify your proof in 14bii) with just that You made the assumption that f(a) <f(b) < f(c) \Rightarrow a < b< c But that's only true if the function is strictly increasing (which is not true ripp)

bruh I legit got it using only 2U knowledge why is this so easy?, but yeah the final result is indeed neat

I honestly don't recall learning the inverse function theorem until first year uni to be fair (and basically never used it from 2nd year and later) , so I doubt the majority of the high-school students would even consider it. Please share some more rants pls this is hilarious.

x = tan\theta

Wow this is definitely harder than the previous years. I see that Carrotsticks having extra assistance from former BOS members (who are also math whizzes :P) definitely revoluntionised the content. However, with the new syllabus being implemented, I wonder what mathematical theorem do you plan...

You can't compare the BOS trials with the HSC. It's just at a completely different level since it's specifically aimed to challenge the students who have mastered virtually every single topics, i.e people who have the potential to easily achieve 95+ HSC. Even if you did do badly, it wouldn't...

Hey so what textbooks would you recommend with the new Stage 6 math new syllabus (2U/3U/4U)

When you're finding the rate, or how fast or slow something is, you use the derivative expression. so for c) you find dS/dt and then sub in t = 5 and your value of k from part b), that's your rate. d)sub S = 4 (as that's the amount that's left undissolved ) and your k from b) Then you solve...

The problem with checking your answers over, is that sometimes you would think it's right in the back of your mind so it could blind you from seeing the mistake. What I would do is that I would read the question thoroughly a few times (even though it's something I'm familiar with), and then do...
