Re: HSC 2013 2U Marathon 2U people ain't that stupid... -\frac{1}{3} cos(3x) +c 0?

2 unit people deserve a marathon thread too... I'll start off with a typical hsc troll question (but abit harder) $ A point P(x,y) moves such that it is equidistant from y = 1 and A(p , q) $ Find the equation at which P moves

ahh crap i forgot about that... well I am the first person who doesn't do 4U to solve it :cool:

thank god, nobody solved it before I got back from my 7hr tutor -.-

give us the question

Re: HSC 2013 3U Marathon Thread I'll do part b later when I have time to teach myself SHM

Is that the whole question? because its not making sense...

eh depends I accidentally deleted my entire 5% done chemistry assignment, and I have a mild cold hence the silly mistakes so I'm kinda annoyed. I'll make the solutions that will direct you to the right path but not the entire thing. Ill upload the solution to question 12 in a moment

I don't understand how you managed to get from pi/4< x< 3pi/4 to 0 < x < pi/4 For these kind of questions they already gave you the answer, so just use it and manipulate your way through. Edit: No not integers values Edit: You're

I just found the equation for t so the rest should be obvious As for part b) I'll give you a clue the value of t must always be positive Question 11 will have the same kind of manipulation For the rocket question 11 same manipulation but watch out for the wording at v = 5km/s the...

aaahhhhhhhh I see thank you~

wait don't you have to times 9 by 2 since the equation is sqrt(2GM/r)

I'm not too sure about the first question I'll have to solve it once my cold goes away. For question 18 look back at your formula sheet and you'll realize that the force is proportional to 1/d not 1/d^2 For question 19 use your right hand palm rule, except flip the direction of the force since...

*spoiler alert* 3 unit students are also ranked against 4 unit students.

That would work if Australia had only had 500 students doing each subject, but unfortunately that can't happen. To be honest we should feel lucky that the board of studies developed a complex system of evaluating our marks compared to other educational systems, such as Korea where their...

I got to disagree on 5 hour tests, that is a nightmare not only for students but also schools and hsc markers. I reckon, there should be two, three hour tests. One on preliminary work and one on hsc, worth 40% and 60% respectively. The sciences should divided up into levels, one 'normal' and one...
