    for year 11 and 12, binders, folders or books ?? any brand suggestions ?

    I remember one of my friends used to have this one big binder for all his subjects and it was pretty sufficient to fit everything. Some subjects you just tend to take less notes and get less worksheets than others so one decent sized binder should be sufficient. Having 7 would be overkill imo.

    This question is breaking my head

    It's from the formula we obtained for tan(alpha + beta \2). You just plug in the values of alpha and beta into the sin and cos equation.

    I did consider it. The Im(RHS) line in mine has the 2cos(a-b/2) in it..

    This question is breaking my head

    \text{If we want to find tan of 5pi/24 we can see if we set alpha and beta as 3pi/12 and 2pi/12 we get 5pi/24} \therefore \alpha = \pi/4, \beta = \pi/6 \therefore \tan\bigg(\dfrac{5\pi}{24}\bigg) = \dfrac{2 + \sqrt{2}}{2 + \sqrt{6}}

    This question is breaking my head

    I just got back home so here's the rest. \text{Now we know}\hspace{2mm}e^{i\alpha} + e^{i\beta} = 2\cos \bigg(\dfrac{\alpha - \beta}{2}\bigg)e^{i(\alpha + \beta)/2} \therefore \cos\alpha + \cos\beta+ i( \sin\alpha + \sin\beta) = 2\cos \bigg(\dfrac{\alpha - \beta}{2}\bigg)e^{i(\alpha +...

    This question is breaking my head

    It's kind of shitty how they put literally 3 questions into one part lol. Anyway \text{We have to show}\hspace{2mm}\dfrac{e^{i\alpha} + e^{i\beta}}{e^{i(\alpha + \beta)/2}} =2 \cos \bigg(\dfrac{\alpha - \beta}{2}\bigg) LHS = \dfrac{e^{i\alpha} + e^{i\beta}}{e^{i(\alpha + \beta)/2}} =...

    Will I be disadvantaged?

    Well seems like you really like the subject and are willing to put in effort. In that case you should be fine. You also have a modern history teacher at your school so if you need any essays marked or something you could just ask that teacher. So imo I don't think you have a disadvantage at all.

    Does anyone regret attending the school that they attended?

    Seriously? Carlingford is such a well known school. Maybe because usyd is filled with private schoolers

    Best English tutoring centre?

    Ouch 12k a year JUST for English?!?!? That's the price of like going to one of the top private schools! Ain't no way I would pay that much when you can get a very good private tutor at $30 an hour

    I've heard very good things about Delta from everyone. Perhaps you should consider that as well?

    Yes students are excelled further but that's because they can handle it. Most students in low ranking schools wouldn't be able to hand it and so they don't go ahead.

    UAC application help please :(

    It might actually say that because they have not gotten an atar yet and so technically have not met the admission requirements. But I don't remember if I had that or not so just contact UAC or something.

    Will I succeed?

    Well past success if often a good indicator of future success. I don't wanna say you will definitely do well as I don't want you to just relax and be like "I'm gonna ace this.", but yes I mean if your able to do well in eco then there should be nothing stopping you from doing well in it in year...
