sin(x) & cos(x) can't be 6 & 7, respectively, because neither function is capable of producing values outside of the range -1<= f(x) <=1. To solve the question, you need to construct a right-angled triangle with lengths opp=6 and adj=7 and related angle A. From this you can work out the...

I think that certain subjects are much more prone than others to be affected by the subjective bias of teachers. The maths and science subjects tend to be much more objective with very clear cut marking criteria and no grey region between right and wrong. A friend of mine, who was dux of Adv...

Thank you for the compliment but I do detect a mild tone of contempt there. Haha. :P It was a fairly easy assessment, but if it means anything, the minimum result was 1/30 and there were quite a handful of single digit marks dealt out. I do agree though that full marks shouldn't be given out...

Physics and Music 2. And I wish I didn't have to choose between Legal Studies and Ext-2 Maths.

Received the rest of that Biology assessment today. Mark: 30/30 Rank:1/45

The situation you described is cheating and there is no justification for that. My school tries very hard to make sure that if assessments are run at different times of the day for different classes, the first classes that sit the assessment are kept inside after theirs have finished until...

My EE1 class used Jasper Fforde's The Eyre Affair in Yr 11 while they studied Jane Eyre but I'm not entirely sure whether it was a prescribed text or was only used as a supplementary text because I wasn't at school for the first term. I don't think you can use any prescribed texts from the...

^Actually, now that you mention it, I do remember reading something along those lines somewhere. *smacks forehead*

My teacher has a fetish for pencil sketches and always growls at me when I do my graphs in pen. I never do what she says though. I much prefer drawing graphs in different coloured pens. It makes everything a lot clearer especially when dealing with manipulations of given functions and...

Oh definitely, I'd say. Very well done. Good luck with your half-yearlies.

Thanks a lot, Iruka. Your contribution is definitely worth a lot more than 10 cents. Hehe.

Ext-1 English teacher, on the ending of A.S. Byatt's Possession: "Sex is all about recreation, and of course, re-creation." It does fit in rather nicely with our Postmodernism elective.

Recently got some more of Term 2 assessments back: Adv English: Mark 23/25 Rank 4/95 (cumulative) Ext-1 English: Mark 10/10 Rank 1/35 Chemistry: Mark 29/33 Rank 1/54 (cumulative) Biology: We got marks for half the paper today. So far 17/17. Hopefully the other half won't...

Yeah I would just be putting the overall equation (even though it hardly ever happens in reality) instead of a separate equation for each of the 3 steps for complete ionisation of citric acid.

kony:

I'm just a bit curious.. For f(x) which has an oblique asymptote of A(x), does the asymptote of g(x) = SQRT[f(x)] become SQRT[A(x)]? Provided, of course, that as x->infinity f(x)>0 & A(x)>0. I had this discussion with my maths teacher and she was very dismissive, yet offered not explanation...

The most recent that comes to mind is element 118 (ununoctium) back in 1999. Glen Seaborg also played with a handful of transuranics (Z=93-102) at Berkeley back in the '40s and '50s.

Ethanoic acid is monoprotic and citric acid is triprotic. If we're to assume complete ionisation in (say) 0.1M solutions of each acid, the hydronium concentration is 0.1M in ethanoic acid and 0.3M in citric acid. So the theoretical pH is -log(0.1)=1 for enthanoic acid and -log(0.3)=0.52 for...

I agree. Legal Studies is a very poorly scaled subject but I would have kept it because I never needed to work at it to do well. I had to drop it at the end of Yr 11 because my silly school decided to run Maths Ext-2 on the same line. My teacher and the Social Science faculty head refused to...

I don't mean to sound harsh but there is no way that you can "fall back" on a subject that you're only getting 40%-60% for assessments and not break your back. It would be wise to drop it as early as possible and focus on your other subjects. Trust me, it's much harder if you are ever put in...
