Good work. Although one of the questions here is cut off. http://neilau.me/search.php?phrase=Haber&course=chemistry

try \dot{x} and \ddot{x} \dot{x}\; \&\; \ddot{x}

For most people, Space is definitely the easiest in terms of concepts and content load. I personally found Motors and Generators ok and easy to understand. But generally, people find that the most difficult in terms of concepts. Ideas to Implementation isn't too difficult with the concepts...

Re: HSC 2017 MX2 Marathon ADVANCED why can the standard V=1/3Ah be using used where A is the area of the base = a^2 and h = a/2

I don't remember sorting them by diffficulty, oh well.

James Ruse/Grammar, Hurlstone/Sydney Tech, other selectives, general schools. not sure where schools like Barker or Knox fit in though

Probably Sydney Grammar, maybe Sydney Boys... I don't know most other selectives, Sydney Tech, Hurlstone tend to be around the same difficulty, I think Hurlstone is slightly harder, but hard to compare. Girraween, hard to tell, but I suspect it is a whole different kettle of fish.

It is how the derivative of cos x and sin x is defined. We use radians instead of degrees as the computation is simpler. for x in degrees \frac{d}{dx} \sin{x} = \frac{\pi}{180}\cos{x}

Errata: the diagram for 2(b)(iii) is wrong, the slope of the line should be 1 not pi/4. One of the angles in 2(c) is named AOD it should be AOC. The diagram in 2(c) should also have the point A but that is just I forgot to put the latex in for that point.

Let me know what files/trials you want solutions done up for. I cannot promise to get them done straight away. I need to have at least the question file. Sample File Moriah 2002 Ext 2 Trials Q1-2 My LATEX Code:
