Look at the wording of the question "The maximum value occurs... dtheta/dx=0 and x is positive" Thus you need to find x satisfying dtheta/dx=0 and x>0 no need to go further

Exactly what I got

6 in the demoniator was from 3! Edit: Ah, beaten

was a good test. It was harder than pastpapers But I managed to finish

lol, unlike the past 3 yr's exams, I found this one harder, giving me a prediction of about 110 At least, it's easier than the very old papers. And your school's top guy should get a state rank lol.. I'm jealous.

How did u go in MX2? Expected mark?

Re: How was it!! MATHS EXT 2 There already is a thread for this.

I got the same, except I'm not sure about the number.

minimum? I thought it was maximum (couldn't be bothered to check it) But anyway, the number I got seems similar to, if not the same as, yours.

LOL wow.. Many found it easier than last year's. For me, I thought it was harder than 06-08, which I killed. But I didn't really kill this one...

What answer did you get? whether or not the guy's head stays out or goes into water

About 110 if without stupid mistakes.

Find the maximum value by differentiating

\int_{0}^{a}f(x)dx=\int_{0}^{a}f(a-x)dx Need to be able to prove this although it's one of the easiest proofs

Thanks to a change in the exam committee, things can't be predicted. I hope the exam will be like 06-08. They were easy.

Well, if he studies, he can get more than that because I and the guy who came 3rd overall now can, at least not under the pressure of the real exam. (I tried hard after 1/2 yrly and he tried hard after the trials.)So I just hope he does studies hard this time. (and lol, I'm not gonna spend $100...

Re: English ESL paper 2 and listening 8 pgs won't help people to see if you are actually in trouble because people's writing sizes and words per page differ. E.g. my 5 pgs=some ppl's 8~10 pgsAnd it also depends on how much you talked about for your related text. (e.g. Had I not seen the...

Well, the number, 2, seems nice, but my cohort in a school ranked in 250's is not brilliant. In fact, they are quite weak, IMO. (except the top 3) But, the guy who topped overall did crappier than me in trials (as expected) and seems like he's not really attempting to work hard. (as evidenced...

lol, threatening wouldn't change the situation.

I'm screwed because my rank will drag me down.
