I tried like 5 times with ratio of intercepts and corresponding angles but I couldn't get it out, was panicking a bit by that point

Definitely harder and more conceptual than previous years. Alignment should (hopefully) allow me to scrape an e4 with like 65-70% raw lmao

rip, i completely missed that the vertical length is R as well. thanks again!

why is \frac{R-h}{R} the lower bound? thanks

Specifically b) and c)

Terry Lee has a 3u book (I've only used my friend's copy of it for binomials, and its pretty good)

MX2 Assessment 1 - 6/6 Physics Assessment 1 - ~10/16 MX2 HY - 1/5 Physics HY - 1/14 In prelim, I was sitting somewhere around 14th for MX1 until the yearlies, where I was able to jump to 3rd by getting the highest mark.

This is the method/process I use to study maths, hasn't failed me yet: 1. Pick a past paper from a particular school, do the whole thing 2. Write down the topics (even better, the specific exercises from your preferred textbook) that you made errors in 3. The next day, study and do some...

For 3U i'll be revising early year 11 topics (mostly trig and induction) as 3U trials test everything you have learned up to that point. As for pre-learning maths, I did it for 4U and 3U over the christmas holidays. IMO it's the easiest subject to learn ahead due to the volume of resources...

Re: HSC 2018 MX2 Marathon No idea how to do ii): I know this isn't the best place to put this but i didn't want to dedicate a thread to a 1 mark question that's apparently simple

Re: HSC 2018 MX2 Marathon where did you get that part from? nice solution btw

Re: HSC 2018 MX2 Marathon I can't load any latex in this thread anymore, I've tried on 3 computers, is anyone else getting this issue or just me?

Re: HSC 2018 MX2 Marathon $\noindent Hint: Draw the loci on an argand diagram and consider circle geometry theorems$

Re: HSC 2018 MX2 Marathon How can you say that the equation is y=0 on the imaginary plane but then sub into an equation that's on the real number plane? Wouldn't you have to sub in bx + ay = 0?

Wouldn't a better idea be something like a captcha requirement for ALL posts? Maybe premium members could bypass this requirement for example?

$\noindent Please keep in mind I have never derived trig functions before as I'm not up to that chapter, so I just used symbolab.$ $\noindent 14. a)$ \angle QOM = \frac{\pi}{2} $ (A line from the centre of a circle that bisects a chord is perpendicular to the chord)$ $\noindent It is clear...

No, you don't have to drop any. As far as I know there isn't any max, you just need 10 units minimum (this might change in regards to tafe or if you are doing non-atar? not too sure). You can do 14/16 whatever units for the HSC if you want. It gives you a bit of leeway if you bomb a...

Ah thanks

Can you pleaes explain how you rearranged it to get \arg\left(\frac{z-1}{z^2}\right) = 0
