Re: HSC 2016 Complex Numbers Marathon I can't think of anything for this besides w = c(u1 +u2) where is c is real...

Re: HSC 2016 Complex Numbers Marathon Whoops, I meant that the chord U_1U_2 is bisected Source: http://www.coolmath.com/reference/kites

Can you explain why you think this? I want your opinion, not what someone else believes.

Re: HSC 2016 Complex Numbers Marathon I have no intention of masking that part of my identity because it's already obvious. I guess your comment has convinced some people

Re: HSC 2016 Complex Numbers Marathon wrong lol (my sol'n)

Let's realise the denominator ;) \frac{1}{1-z} = \frac{1}{1-z} \frac{\overline{1-z}}{\overline{1-z}} = \frac{1-2\cos \phi}{|1-z|^2} + i \frac{2 \sin \phi}{|1-z|^2} Now we take the real part! Re \left( \frac{1}{1-z}\right) \\=\frac{1-2\cos \phi }{|1-z|^2} \\= \frac{1- 2\cos \phi}{|1-2\cos...

For a second, I thought you were using Ma..Tri..Ces.. and got excited

Oh, haha lol, well... I think the cause is that your brain allocated no resources to System 2 (https://en.wikipedia.org/wiki/Dual_process_theory) i.e. mindlessness :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P :P...

RIP in peace?

yep, XYZ

Re: UNSW chit chat thread 2016 Why would it have a WAM requirement to drop from a double to a single?

Re: HSC 2016 2U Marathon Sadly... slight derail but what's the reason HSC doesn't want to teach students the beautiful maths notations and proper way of defining functions?

Re: HSC 2016 2U Marathon 2U HS students don't learn this dense notation so it's going to take a while for them to comprehend it unless they were already used to it in the past posts...

The roast was fun though :P

Re: HSC 2016 3U Marathon lol

Re: HSC 2016 3U Marathon Interesting claim. Could you reveal your reasoning? Or identify the premises.

Re: HSC 2016 3U Marathon I'm an ambitious detective :P

Re: HSC 2016 3U Marathon No. You can examine our past posts and make this deduction and it's highly unlikely there is one person being active on both accounts and who is that careful with their word choice, thoughts, activity, etc. Question. When six fair coins are tossed simultaneously, in...

Re: HSC 2016 3U Marathon o__O I saw how you used [IMG] to get the LaTeX'd equations. Just providing an easier way to do it lol

Re: HSC 2016 3U Marathon Simultaneous equations! btw [tex.]\sin^{-1} (x) + \cos^{-1} (x) [/tex.] without the red dots yield \sin^{-1} (x) + \cos^{-1} (x)
