A composite number is a positive integer which is not prime. Note that 1 is neither a prime number nor a composite number (at least that is what I gather). The first few composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16... You can find more about composite numbers at mathworld. So herein...

Question #X: 20 cards, labelled 1 to 20, one card is chosen, find the probability that its number is composite or >12.

Maths in focus 1 & 2 Pros: Clear layout, ok proofs. Cons: Not challenging enough, mistakes here and there, not enough examples, no summaries, boring questions, the examples don't show you how to solve the harder questions. Not a big fan of these books, even if I've been using them for the...

So what mark are you expecting? This is probably the worst french exam I have done to date... Speaking - 19/20 Listening - 25/25 Reading and responding - 30/40 Writing - 11/15 Total: 85/100 I usually get 90+ :(

How is it the same? Language features implies just that: features of the language. Now not only does Cinema Paradiso NOT CONTAIN ANY FUCKING ENGLISH SPOKEN LANGUAGE, but to add to that bullshit it is a MOVIE. I don't see how you could possibly correlate camera shots with language features. The...

No you got it :). I know, it was an easy question, just that it's so simple some people get stuck ahahah.

Answer to question 46: By expressing sec(x) and tan(x) in terms of sin(x) and cos(x), show that sec2(x) - tan2(x) = 1. Question 47: Given log72=0.36 and log75=0.83 find log714 Note: Nasty trap, this is a part of a longer question, you may therefore disregard some of the given information.

Answer to question 44: Prove that the sum Sn of an arithmetic series is 1/2 n (a+l) where n is the number of terms in the series, a is the first term and l is the last term. Question 45: Differentiate y=log2x

Ok I understand my mistake in Q41. Gosh I feel stupid now. I had forgetten that it had to be linear :o. Thanks for pointing it out.

Gosh that question on cinema paradiso was absolutly horrible. What language features? Come on what is this bullshit? I had studied camera shots, use of music and then they ask me a god damn question on language?? In a movie? I wrote three pages of absolutly incomprehensible rubbish for that...

Q41 Answer:

Why Slide Rule? He's like a total math newb :D!

What pisses me off is that the HSC is a test of time. My handwriting isn't particularly messy but I write very slow (Don't ask why, I've just never been a very fast writer). As a result it is all too common for me not to finish my exams, even when I still have a lot to say the time just runs...

Yeah I pretty much bullshited the whole ellipsis question. I think I talked about continuation, how this issue wasn't resolved yet and that the debate would go on or something. I had trouble translating that last line into english. What about the question about the principal's tone/ his...

God that took me forever, don't post long questions like that again lol seriously!

The hacker was initially doing it for the fun of it, as a sort of game, but then it went on to become an intellectual challenge, a test of his intellectual abilities if you like. He was also motivated to damage organisations that breached human rights. Well, something of that sort anyway. Ah...

Q32 Answer: When you said 'or', you actually mean 'and' don't you? Anyway: Question 33: Show that the equation 2lnx=ln(5+4x) Note: This is q23 from HSC(1993)

Not to mention that the advance essay question was tenfolds easier than the ESL question. Sometimes I wonder why I dropped advanced to ESL. Advance and standard has this really simple generic essay question that any prepared essay could basically fit without any modification. I see too much...

It was definitely a lot harder than I expected. There wasn't much pause time between playings of the listening questions so I had to come back to finish my sentences a couple of times. I'm pretty sure I'll get close to 100% for listening but that's because I'm a native speaker. The reading...

Q30 Answer: Question 31: Find the derivative of 2x Hint: This question involves logarithms.
