Oh I am reasonably confident that the media will have a field day when that happens, and they will almost certainly find some way to mention 'too many Asians in selective schools'.

I don't know about China, but Hong Kong is crazy. I may be wrong, but according the document attached, it seems like the students sit 2x 3 hour exams... on the same day! The first from 8:30am to 11:30am, then 1:30pm to 4:30pm. In terms of difficulty, it goes quite well beyond Extension 2. A lot...

Was sorting out my photos from my trip to Vietnam last year and found some photos that I thought some of you may appreciate. One of the children was in Year 10 and was doing inequalities that we do in Extension 2 Year 12 here in NSW! A lot of the inequalities there were well beyond Extension 2...

Re: MX2 2016 Integration Marathon Yes it does. It will be some giant rational number. We only really talk about 'closed forms' for infinite sums.

Re: HSC 2016 3U Marathon For the spirit of this thread, perhaps you'd like to actually answer the questions rather than providing what is more commonly known as 'proof by intimidation'. Yes, many of these can be done by inspection, good for you. But the reality is that there are several...

Just ignore saltedwound guys. He/she is either a troll or a complete ignoramus. In either case, they are to be ignored.

I don't think the HSC would have pinched it from a school trial. Almost all standard courses dealing with infinite series will at some point have the proof of the p-series converging for p>1, and it most likely would have been the typical integral test proof.

OP is a Year 12 student Extension 1. These are not in the scope of the HSC syllabus. Also, these aren't particularly difficult problems. I am almost certain that my Year 11 class, who just learned Chain Rule less than a week ago, could do the second problem, given a 30 second introduction on...

In general, no. Usually, you have to add in a fairly strong condition in order for a property to hold for both Z and Z conjugate. For your above statement, we need A, B and C to either be all real and/or all equal in order for equation to also work for Z bar. What is this 'operator'? I have...

Re: MX2 2016 Integration Marathon Sigh ignore please. http://i.imgur.com/I446dGA.jpg

Yes. That is, after all, the essence of teaching. But knowing more is of course desirable too.

Maybe 'weaker students' would be a better term to describe them. To some degree it comes with experience, yes. But some people just have a knack for explaining things spot on without any experience. You don't necessarily need to be mathematically gifted and be extremely knowledgeable to explain...

I think 'dumb students' is a rather derogatory term to describe those who do not perform as well as others. There are a plethora of reasons as to why they may not be performing as well. I should hope that I don't have to actually explain them to you here. In my experience, I've learned that...
