the point P(x0,y0) lies on the hyperbola x2 / a2 - y2 / b2 = 1 (i) Show that the acute angle @ between the asymptote satisfies tan@ = 2ab / (a2 - b2) (ii) If M and N are the feet of the perpendiculars drawn from P to the asymptotes, show that MP.NP = a2b2 / (a2 + b2) (iii) hence...

1. Contact Australian national university and enquire, if you can't find anything on the web.

1 \< |z+2| \< 3 the bigger circle is that graph. edit: biggest.

just draw the diagram : O?

It isnt a remark as a such Kujah, but rather they check for clerical errors, i.e. typed ur marks wrong into the computer.

I think u should "get a grasp of reality" and accept this fact :]

Runnable, schools that are below a certain rank...say 50ish, are not stable. I.e. The schools rank will flactuate GREATLY every year. So it's hard to determine anything. I'm sure many schools could change up to 400 ranks every year. Only schools that peform consistently, such as...

some polynomials questions are tricky :]

ronkee its sin^ m (x) cos^n (x) not sin^ n(x) cos^n(x) the powers are different.

For me: Yr 12 >>>>>>>>>>>>>>>>>>>>>>>> Yr10 > Yr11 In year 11, if you choose subjects your enjoy, then it is less stressful then yr 10 (where you have stupid subjects. However in Year 12, you'll stress about your assessment marks, where as in year 11 it doesnt really...

If u get 4 credits ( and 1 decent band 5) , u'll be in the 97-98 range. Its not ez

u need 2 do much better. simple. Top 25% of every subject atleast.

2x^3 + 4x^2 - x +8 = (x^2 -3x +2)(2x+8) + 19x - 8 2x^3 + 4x^2 - x +8/(x2 – 3x + 2)=[(x^2 -3x +2)(2x+8) +19x-8]/ (x2 – 3x + 2) = 2x+8 + (19x-8)/(x2 – 3x + 2)

foram will never win lol.

yes

Oh I see Care to explain :] ?

??? Q5: An astronaut set out in a spaceship from earth orbit to travel a distant star in our galaxy. The spaceship travelled at a speed of 0.c. When the spaceship reached the star the on-board clock showed the astronaut that the journey took 10 years. An identical clock remianed on Earth...

I'm not 100% sure. I've heard people mention this while browing these forums. Also, whats the deal with Q5 2003 HSC. In my success one book it says. No answer.

Does anyone know the removed relativity hsc question in 2007? or was it 2006? any official links / publications would be much appreciated. or maybe it was some other year.. :
