A friend of mine got a UAI of 92.3 and he wanted to do Commerce@Usyd. Basically he is wondering what the difference between Commerce and Economics is for first year, and how hard it is to transfer. Like are the requirements still 50% UAI and a distinction average? And how many places do usually...

At the moment I am still undecided as to what I want to do at uni next year. Basically at the moment I have narrowed it down to two: either Com/Law@USyd or Actuary@UNSW. On the one hand I have wanted to do law since like year 5. However, the older I have gotten the more I have though that I...

This is from Arnold, P(asec@, btan@) lies on the hyperbola x²/a² - y²/b² =1. The tangent at P cuts the x-axis at X and the y-axis at Y. Show that PX/PY=sin²@ and deduce that if P is an extremity of a latus rectum, then PX/PY=...

Going over the first module, I've got the following questions. Some a bit random, so any input on any of them would be most welcome. 1. In the practical for testing alkanes/alkenes with bromine water, what is the equation for cyclohexane + bromine water as well as the one for hexane + bromine...

From Patel's blue book: 1.Show that the line lx+my+n=0 touches the (a)ellipse x²/a² + y²/b²=1, if a²l² + b²m²=n² (b) hyperbola x²/a²-y²/b²=1, if...

I'm having trouble finding information on this dot point: gather, process and present information on the features of the local town water supply in terms of: -catchment area -possible sources of contamination in this catchment -chemical tests available to determine levels and types of...

These are from Patels book, 1.The nozzle of a water hose is at a point O on the horizontal sround. the water comes out of the nozzle with speed U m/s. Neglecting the air resistance, prove that the water can reach the wall at a distance d from O, if U²>gd, where g is the...

For this module I'm doing Frontline, but what I'm really struggling to get a grasp of is the whole idea of representations. Like I understand the concept of telling the truth and how it is manipulated throughout frontline. But how exactly does the representation fit into the whole...

So what's the deal with Harry Kewell? Is he off to Liverpool or not. First it's on then it's not. It seems as if he wants to go to Liverpool, but Leeds just want to get as much money out of the deal as possible, and who can blame them with all their financial worries. It seems as though there...

I'm having trouble with the questions from the Patel blue book, partly because I don't do Physics but anyway here's one of them: A smooth block of mass 2kg slides down an incline making an angle of tan^-1(3/4) with the horizontal. Find the acceleration and the magnitude of the...

A ball is projected so that its horizontal range is 45 metres and it passes through a point 22.5 metres horizontally from and 11.25 metres vertically above the point of projection. Find the angle and speed of projection.

I've had a look at the responses to Blade Runner/Brave New World and King Lear from 2001, the Band 5/6 ones and I didn't think they were all that brilliant. When they say Band 5/6 does it mean it can be a low Band 5? Or are most of them Band 6? Same question for 4/5, etc

Only after I did the comp did I realise that some of the guys on this forum actually set the comp. The thing that got the bells ringing was the question about Bambul. I guess I didn't join the dots when my teacher tolds us about the comp a week ago and having see Bambul and others with Ecos+Bus...

An open tank is to be made of sheet iron; it must have a square base and sides perpendicular to the base. its capacity is to be 8m³. Find, correct to the nearest centimetre, the side of the square base, and the depth, so that the least amount of sheet iron may be used. I'm...

What do you guys put down the rise in the exchange rate over the past couple months to?

ABCD is a cyclic quadrilateral such that AC is a diameter, DC produced meets AB produced at S, and BC produced meets AD at T. Prove that ST is parrallel to the tangent at A. Also it was has been established that BSTD is a cyclic quadrilateral with ST as diameter.

What is the difference between these two?

I've got two questions, (1) An n-sided regular polygon is inscribed in a circle. Let the ratio of the perimeter of the polygon to the circumference of the circle be p:1, and let the ratio of the area of the polygon to the area of the circle be a:1. Find expressions of p and a as functions of...

If you're asked to write a net ionic equation for the reaction between an acid and a base, what ions would you exclude? What I am referring is something like: (i) potassium oxide and sulfuric acid (ii) barium hydroxide solution and nitric acid.

Would someone please be able explain to me the main differences between the World Bank and the IMF.
