Re: Hmm... Tone: positive/negative, resisting/embracing, optimistic/pessimistic, general implied attitude of composer towards responder. In visuals, it may involve colour. E.g. The Door's tone is one of encouragement "Go and open..." beckons one to do something. Angles: if you're...

No, inequalities are NOT hard. Here are the usual tricks: 1. Bring all to one side and prove either strictly non-negative or non-positive (whether it be <= or >=) 2. Try AM>=GM ALWAYS (even if you can't see it). See a product on one side and a sum on the other? Think AM>=GM. Can't see...

TONE is v important. I've seen 1 or 2 change papers where they ask what the tone of this-or-that text is, and how it conveys change. Visuals - u could mention angle (bird's-eye or worm's-eye) Also, you have to link techniques to text type (e.g. news article - subheadings, captions, film -...

I think it's almost 100% certain we're gonna get a sept-11 article as one of the "change" texts for comprehension, so start thinking about how has 9/11 changed things.

Memorise quotes and examples of techniques, and practice relating these "evidence" to areas/modules: change, etc. Put in connectives and you have paragraphs. IMHO you don't need to memorise connectives. Oh, and also memorise parts of a good introduction. You should have several ideas...

I got 270 as the answer too. Some sydney boys teacher has some real competence problems.

Ok, then there's one more sample space: 5,5 so p = 2/11 If confused over probability, draw a box diagram

Well since you notice that "ONE" face was a 5, that means that the other one isn't. So sample space = 10: 1,5 2,5 3,5 4,5 6,5 5,1 5,2 5,3 5,4 5,6 Two of these give a sum of 8. Thus probability is 2/10 = 1/5 :rolleyes:

I'm sorry to say that not only is 8C3 NOT obvious, it's also wrong. For argument's sake, lets rename the 1st E "E1", and the 2nd E as "E2" Then there would be 8C3 different ways of choosing 3 letters from the now-distinct 8. However, now remember that in the real question, both E's are...

At my skool, everyone believes me when I give them my answer...you can trust me...

I've NFI. It would work for 4u, but 3u? I've to ask my teacher.

The answer IS wrong. Here's the right way: FREQUENT: there are 7 different letters, and 2 'E's So there are two types of 3-letter words: 1) Two 'E's and something else: the "something else" is one of the 6 non-'E's (i.e. F,R,Q,U,N, or T) and this "something else" can either be in the...

Here's a nice little alternative proof: Consider the centre of circle, O, and consider the line, l, through O, perpendicular to all 3 chords PQ, RS, LM, and intersects these chords at A, B, C respectively. Since l is perpendicular to all 3 chords, and l passes thru centre of circle, l...

My advice would be: If in doubt, try it anyway. Tricks like integrating/differentiating are like cards - u don't always need to use them. It's good to have them in your hand anyway. When a question involves integrating/differentiating, when you use the trick to goto the next step, it's...

ditto

My teacher tells me the question 8 is supposed to separate the top 10 in the state from the rest...so i guess, aim to get 6 and a half questions right wot's that? 97/120? jus my guess...

From the property that cos(x) = -cos(x + pi) (draw a circle diagram and see for yourself) Thus, cos(5pi/8) = -cos(-3pi/8) since cos is an even function -cos(-3pi/8) = -cos(3pi/8) :rolleyes:

Well, actually, the definition of |x| = sqrt(x^2) :apig:

The stuff you quoted was the mathematics of doing this: We've p(y) = 8y^4 - 8y^2 + 1 and we've determined that when y = cos(x), p(y) = cos(4x) When p(y) = 0, cos(4x) = 0 Then ask yourself, for what values of x are there (0 <= x <= pi would suffice) such that cos(4x) = 0 ? these are...

yeh right...:rofl:
