Re: Dear HSC students: where are you up to in Chemistry? I think we're a module behin dw you're not alone, just started our 3rd module after zooming past acidic in the last of couple of days haha

By squaring both sides. By squaring the LHS, we get rid of the square root. When we square the RHS, we expand it (A+B)^2 = A^2+2AB+B^2

Yup, it has pree interesting questions and the examples are also very helpful

$\noindent Using the double angle expansion (that $\cos 2 \theta = 2 \cos^2 \theta -1), \\ $ the expression simplifies to $\cos \left ( 2\times 30 \right )= \cos 60 = \frac{1}{2} \\ \\ $If you haven't learnt double angles yet, then use the absolute values of trig ratios to simplify $\\ 2 \cos...

yeah I guess, but I'd prefer past papers as it more closely resembles the actual exam. Doing them in exam conditions would be a good idea

Revise through the content and make sure you're thorough with all of em. spam past papers and learn from any questions that you answered incorrectly.

lmao dw you got this bruh

Thanks! I'm thinking of doing something related to maths/physics, possibly research stuff in physics, not sure yet. and yeh there is this future leaders scheme for usyd for dux and school captains

Tyvm for the estimate guys, much appreciated phew thanks for that estimate mate! It's higher than what I expected :)

z^5-4z=0 \\ \Rightarrow z(z^4-4)=0 \\ \Rightarrow z(z^2-2)(z^2+2)=0 \\\Rightarrow z(z+\sqrt{2})(z-\sqrt{2}) (z+\sqrt{2}i)(z-\sqrt{2}i)=0 \\ z=0, \pm \sqrt{2}, \pm \sqrt{2}i\\ \\ \\ $another way to solve $ z^4=4: \\ z=\sqrt[\frac{1}{4}]{4} \\= \left ( 4cis( 2n \pi) \right )^{\frac{1}{4}} \\ =...

well our school kinda excels at the humanities subjects with most of the B6s and SRs in subjects like English adv and standard, legal, history etc

:)

I'm getting an eyeseeyou vibe here

Nooooooo... Was really hoping for 4u in the morning, hate tests that are in the afternoon :(

2. Yes, it should be -(2√3)/3 3. Yes, it should be 109.70m 4. You are correct for both parts, they are indeed htan79 and 108m

OH GREAT!! See you there mate :)

Did anyone get in?!

yup they removed it now. I guess they will upload a new one on the 26th this month

So just wondering, did anyone here apply for the ISS usyd program?

This is really helpful, thank you very much
