Re: HSC 2013 4U Marathon To be fair I feel compelled to say that they're not exactly easy questions. I think I would've had considerable difficulty with those questions when I was first beginning with Extension 2. I would be probably correct in saying that most students just beginning with...

Re: HSC 2013 4U Marathon Is this from Cambridge?

Re: HSC 2013 4U Marathon Actually, my bad. It's actually correct. Stop trolling bleakarcher :P Sorry, it's been a while since I've done complex numbers.

Re: HSC 2013 4U Marathon With respect, that is wrong... |z|=|w| is, however, correct.

No need to patronise. It was when I was in high school.

Re: [The Mathematics CORNY Pick Up Lines THREAD] Albiet slightly off topic, I actually ending up becoming best friends with a girl who I met after I solved a maths question for her. I'm actually not kidding...

Re: HSC 2013 4U Marathon I think he said that quite a few students got close but didn't quite manage it (were a few marks short). He marked Q8 too that year.

Re: HSC 2013 4U Marathon I think Peter Brown from UNSW wrote Q8b of the 2003 paper. Apparently no one got full marks for Q8 that year.

Re: HSC 2013 4U Marathon 1/n! = 1/[n(n-1)(n-2)...(3)(2)1] < 1/[2.2.2...2.2.1] (as n, n-1, ... , 3 > 2 for n >= 3) = 1/2^(n-1) New question: Expand and simplify (x-a)(x-b)(x-c)...(x-z).

Admittedly I "rote learnt" maths in Year 11. For example, for the subsidiary angle method I used to memorise that when cos was first I would use the transformation R cos(x-a) and when sin was first I would sue R sin(x-a). I had no idea why though... I still did fairly okay though.

I think Harder 3U and Graphs were added in 1989? The 1981 paper looks quite straightforward though, which is expected because it was the first year that the new 4U course was examined (they added in conics and circular motion and took out matrices mainly).

Re: HSC 2013 4U Marathon I don't think Ellipses with centre other than O are in the syllabus...

I think it's really stupid for your moderated/aligned mark to be that different from your raw mark... It's inevitable that moderation/aligning would be required for an entire state, but I think the differences at the moment are way too much. If the aligned marks and raw marks differ by at least...

I like carrots. Mmm carrots...

With all due respect, if you need worked solutions for MIF then you should review the basics...

Thinking about it, I think I like things with not much reading but has every step clearly shown... but that's probably because I hate reading...

Re: HSC 2013 4U Marathon What's a "Polylogarithm"? And that question can be done using 4U methods.

You could work at a bank.

Most girls are more straightforward than you'd think... And as for me, I'm always sweating like it's 35 deg when it's only 15C, and no person (girls included) would like to touch that. But honestly, I don't think it's THAT bad... Why is it even a big deal? To be honest, if it's a good friend...

Re: HSC 2013 4U Marathon Lol P Brown... Did you do it this year?
