Re: First Preferences? That one, yeah - but it's my 6th (for now) so I doubt I'll be seeing you at orientation day. I reshuffled my list, yet again. Sigh.

I'll write down some hints so you can try the questions for yourself. The full solutions & explanations are under the spoilers. I think BOS should set up sub-forums for all preliminary subjects like they have for HSC subjects. All these questions rely on your ability to write down...

Try Terry Lee. He's got pretty coloured diagrams, too.

Re: First Preferences? This is what it looks like now. I only filled in 7 preferences. Hmm. This isn't good. I think I will be deleting the ANU ones and I'll end up with 5. I can't think of anything else to put in there. 1. 428000 B Medicine/B Surgery, B Arts/B Medicine/B Surgery UNSW 6F 95...

It 's very important for you to consider how hard you have had to work to obtain these past results and whether you have enough reserved efforts to put towards Ext-2 Maths in Yr 12. Although it is an extension course, remember that Ext-2 Maths is in fact a 2-unit subject and many would agree...

I do those exact subjects. How well are you doing in Ext-1 Maths and how far have you stretched yourself in order to do this well? If you feel confident about taking Ext-2 Maths then sure, just do 10 units. Most schools would still insist that students keep at least 11 units and sit for 2U...

Re: First Preferences? I've also heard that your chances for being accepted into a course decreases as UAC moves further down your list because of the set intake quota for each course. So say that you listed Bachelor of X at UX as your 3rd preference. The course has a UAI cut-off of 9x.xx...

Let z = x + iy and solve algebraically. Scroll over the spoiler for the solution and explanation.

Spec 2 Q4 (c) The polynomial P(x) = x³ + ax² - x - 2, where a is a constant, has three real zeros, one of which is twice another. Find the value of a and factorise P(x) over the real numbers. Let the roots be p, 2p, q Play around with sums & products of roots & solve them simultaneously...

Re: Cambridge specimen papers,Qs I'm assuming that you meant the Polynomial questions only. I will do Spec 2 Q7 (a) and you can use the method to try Spec 1 Q7 (a) for yourself. Show that the remainder when the polynomial P(x) is divided by x² - a² is (1/2a)*{P(a) - P(-a)}x + (1/2)*{P(a) +...

Re: First Preferences? SoulSearcher: I'm just a bit unsure as to the order in which I should put the two. That's why I put the UAI cut-offs there. Not for whatever else reason nichhhole seems to be good-humouredly implying - UAC won't look any further down my list if I satisfy the criteria for...

i) Yes. ii) A max turning pt means two things: dx/dt = 0 (i.e. the particle has stopped to change direction - in this case from moving right to moving left) d²x/dt² < 0 (i.e. the particle is deccelerating)

But surely one day we will run out of phosphate rocks... :p

Advanced English: Nothing specific - but Yr 11 studies should have enhanced your overall ability to comprehend, interpret and evaluate texts and to synthesise your ideas in a composition with sophistication. Maths (all levels): Absolutely everything you've ever learnt through K - 11 is...

I agree with that. Capacity and passion are both essential. I never enjoyed study English as a subject, but my marks led my English teachers to strongly recommend that I try EE2. I realised after a term that I had no passion for it. I've since ditched EE1 as well because my other subjects are...

Write out the first 3 values of x for which sin(2x - 1) = 1 i.e 2x - 1 = 2npi + pi/2 where n is an integer [use general solutions] First 3 values: 2x - 1 = pi/2, 5pi/2, 9pi/2 Solve for x.

Re: First Preferences? I need some advice please: B Sci (Adv)/MBBS @ USyd (cut-off 99.95) or MBBS @ UNSW (cut-off 95)? It's a tough toss. I was told by a family friend who worked in the med faculty at USyd that their course structure is very poor. She kind of implied that I shouldn't bother...

If you don't enjoy a subject and aren't counting on the units - drop it. There is no need to put yourself through unnecessary hassles. If you do like science, it may be wise to consider changing to Senior Science, provided that your motive for dropping E&E Sciences is not due to lack of...

I will provide hints so you can try to solve these questions on your own. The solutions are under the spoilers. 1. If 3 is a root of the equation x² + kx-6=0, find the value of k. Hint: In plain English, x = 3 satisfies the given equation. 2. Express 4x² in the form A(x - 1)² + B(x - 1) +...

So how did your subject selection go? If you did take up Ext-2 English, here's a free piece of advice: make sure that you have passion in whichever area you direct your major work and don't let your teachers steer you around the world chasing after their ideals. I'm not sure what your...
