For example, I'd never be able to answer a 25 mark question on the Korean War alone. Would it only ever get as specific as "Assess the impact of the early crises on the development of the Cold War"?

They seem to be a plague in my essays...

The region bounded by the curve y = sqrt(1-x^2) and the x-axis is rotated about the x-axis. Find the volume of the solid formed. This is pretty straight forward, but they've simply found the area between 1 to 0 and not 1 to -1, so they found the area of a hemisphere. I thought you just find...

http://www.youtube.com/watch?v=X5sF06nBPeg You know, I never really understood what electricity was, but holy shit, this video explains it perfectly. It is succinct and its clarity is unrivalled. Even the Motor Effect is explained in sheer brilliance @ 15:00 - 17:30. 18:10 - 20:00 is...

So I came across a question in the 2007 HSC that required you to solve an exponential equation. I haven't learnt this at all...more the reason to love Maths in Focus. Seriously thinking about picking up a better textbook, it's trash. Anyway, so if anyone could teach me how to solve this...

Consider a square, single coil of wire (ABCD) of side length 0.30 m which is free to rotate about its central axis and placed in a uniform magnetic field of 81 mT. The diagram shows this looking downwards onto the plane of the coil. Diagram: http://puu.sh/2Cioj When the coil is connected...

An 82 aligned to 86 in the past.

In a trial HSC exam: Q22) A satellite is planned to be placed in a circular orbit 20 500km above the Earth's surface to be part of a GPS array. The satellite has a mass of 1000 kg. (radius of earth = 6380 km, mass not sure, maybe 6 x 10^24) (a) Calculate the GPE of the satellite before it is...

I don't know how to work this one out. 15) In order to escape a planet's gravitational field, a projectile's initial velocity needs to be equal to the escape velocity. During its escape the projectile's kinetic energy is transformed into gravitational potential energy. A projectile is...

Once I finish school, I'm thinking of doing an Extension 1 bridging course. At the moment, I'm getting in the 90s for all the exams (official and topic). I've heard conflicting opinions on it: - Failure rate for those who only do 2U is greater than the failure rate of those who do 3U...

I've never really learnt how to do this. A step-by-step process would be nice :) http://puu.sh/2kkFm Thanks

What if the person ranked 1st for assessments bombs out in the exam and gets like 30%, while everyone else gets higher? Does it mean everyone's moderated assessment marks become 30 and below?

I've made two quick graphs using https://www.desmos.com/calculator/ and the Raw Mark Database: http://community.boredofstudies.org/showthread.php?t=269611 Effectively you can click and run your cursor along the (very rough) line of best fit to see what raw marks in certain subjects are when...
