Well, the only problem with the OP's exam is that it may be hard to distinguish those who are able to use their knowledge, and synthesise a solution, to those who got lucky. The problem with getting lucky is that in the actual HSC, there's much less chance of getting lucky. One of the perks of...

I don't know what you're talking about

Sounds good, I'm interested :)

Thanks! Good work :)

Re: HSC 2013 3U Marathon Thread Hopefully I don't make a typo (the c's and x's are too close to each other on the keyboard). What 3u topic is Sy123's question? Here's my 2 cents: f(x) = ax^2 + bx + c f'(x) = 2ax + b f[f'(x)] = f(2ax + b) = a(2ax+b)^2 + b(2ax + b) + c = 4a^3.x^2 + 4a^2.xb +...

At which point did it become frozen? During export, when you imported a clip, etc?

Wouldn't it be more beneficial to be accelerated either way? If you're going bad, at least you get a practice run and can do it again the following year. If you don't like the subject, then you can get it over and done with quicker. If you like the subject, then good for you. I don't think...

Anyone hear about how everyone in the state went when the format of the essay was reverted to pre-2009?

Good luck! You're nearly there! May your efforts pay off.

For Ngo & Sons, you'll get plenty of questions to do, so resources are fine. The teaching is good, and if you don't understand explanations the first time around, you can ask questions (it is encouraged). Of the teachers that taught me there (Truong Ngo, David Mai and Daniel Yang), they were all...

Generally, if the locus involves the distance between a point to a line, you would probably have to use perpendicular distance. There's really no other way by 2-unit methods that can conveniently compare the distance of a point to a line. What you did was assumed a variable point that moves...

HS'A+', HS'C' not good enough

Re: 99.90 ATAR Experienced Baulko Graduate - Tutoring for Mathematics, Physics, Econo I really recommend Lenny as a tutor! Even though I’ve only had him for a short while, it was a valuable experience. He’s a great person to talk to, and really cares about your education. He definitely knows...

Re: Thoughts on CSSA 2U Mathematics Exam?? Question 16 was fairly easy for me but for some reason, I didn't see the tan substitution thing in question 15 (the one with the cylindrical thing in the roof) -.- I should have been able to see that. Overall, pretty sure I made a lot of silly...

Overall an okay exam, though the amount of space given for the first 6 marker is insufficient. I thought there were no C's as well, but apparently there was one =/ Ah well, ahah.

Ahahah, speak for yourself! I had an exam that started around 12, so I kind of crammed until fairly late, then woke up at 10. It's sufficient enough sleep :P

I just realised, I left the packet of bread at Hungry Jack's LOL I Realised Nothing at the time because of the Cash, and I wasn't Constantly being Examined about whether I forgot stuff or not. Overall though, it was a great day. Thanks to everyone who helped out and organised the event :)

It's an arithmetic series so you know Tn = a (n-1)d where a is the first term, d is the difference and n is the number of terms. To get the sum of the first n terms, use Sn = n/2(a + l). Those are the formulas since you were looking for one. It's a topic called Series and Sequences if you're...

@ Lolsmith- Hey, thanks for your concern, I think, as you can see, jadenmaccas is actually quite the achiever in science, averaging around 90 in assessments. It's just one of those times where a mishap occurs, a common situation where a student did not do as well as he or she would have hoped...
