Re: Extracurricular Integration Marathon Thank you. The spirit of this thread exists in the solution methods, not the answers. This is still not fully consistent with the below post, but I'll drop the case as an answer has now been given, regardless of its true origins.

Re: Extracurricular Integration Marathon No, I must insist. Just a brief and general outline will do.

Re: Extracurricular Integration Marathon Didn't look like a joke to me. Looked like taking credit where credit was not due. But I'll humour you. Explain the your first "wild guess" then. I'm sure we're all fascinated to see how you guessed such an answer, whilst refusing to provide at least...

Re: Extracurricular Integration Marathon And by 'inspection' you mean 'Google' or 'Wolfram'? Nobody's buying it, mate.

Re: MX2 2016 Integration Marathon I'm just gonna say this because nobody's called you out on it yet. You have a very condescending and arrogant tone when you say things like "Next time, check your answer before you post it" or pointing out trivialities. It is very clear what Drsoccerball...

\\$1990$.

You're not.

Re: MX2 2016 Integration Marathon u=1/x along the the identity atan(x)+atan(1/x)=pi/2 may be fruitful for this particular integral.

Go to http://community.boredofstudies.org/private.php Then on the left there is a box called "My Messages". Within that box should be a "Sent Items" box.

I talk a little about out-of-syllabus content purely for the sake of interest and occasionally for more indepth understanding (if it is reasonably outside of course). However, I do not think it helps them understand what is in or out of the course. If anything, it would confuse them. "Am I...

It is (relatively) well-known that the director circle has equation x^2+y^2=a^2+b^2. I'll not prove this as it is a fairly standard textbook question. As Integrand had suggested, we fix the ellipse and 'wrap' the perpendicular tangents (the XY axes) around the it. Let the intersection of...

Firstly, your first paragraph doesn't address my first point (asking you how does out-of-syllabus content help acquire state ranks). I hardly think "It gives you a better understanding of what's in syllabus" is a sufficient reason (if it even constitutes a reason). Re: Terry's son, a little...

Do tell me how out of syllabus content benefits higher achieving students in acquiring state ranks. One could argue that they actually ARE popular. Advertising 'everywhere' is not cheap. Where do you think that money comes from?

Re: HSC 2016 4U Marathon - Advanced Level \\ $Pick two points $ P $ and $ Q $ such that $PQ$ is vertical and the tangents are perpendicular. The chord $ PQ $ must be a vertical tangent to the internal ellipse. By symmetry, if the tangents are to be perpendicular, then the tangent at say $ P$...

As you wish. Good tips here.

But they can very well be taught independently of each other at this stage. I see no reason why if one is introduced, the other must be dragged along with it. Statistics is a vital and pretty much new topic, which is why it is being introduced. If matrices are to be introduced, it would have to...

I hate to be negative, but if you think that the Extension 2 Cambridge (Arnold, I presume) is 'good in general', as well as mentioning Couchman for Extension 2 (there is no Extension 2 Couchman book), then I think your opinion on this is to be taken with a kilo of salt.

The changes have NOT been finalised, though the proposed changes are listed in the document I linked in my original post. The idea at the moment is to begin it in 2018/2019. In other words the first teaching of it in 2018 to the Year 11's, who will then go on to do the first 'new' HSC exam in 2019.

It was terrible.
