Re: HSC 2013 3U Marathon Thread $assume \log_2 3 = \frac {x}{y}$ \; $with x and y an rational integer$ $since \log_2 3 > 0$ $therefore x,y is greater than 0$ $when we rearrange the equation we get 2^x = 3^y $since x > 0 $This will imply that 3^y \; \text{is an even number...

Re: HSC 2013 3U Marathon Thread This thread is as dead as a roadside pigeon ): ... 1. Prove by mathematical induction that for all integers n\geq 5 that n^2 is less than 2^n 2. Prove by mathematical induction that for all integers 3^n \geq 1+2n I'm posting these because I haven't got a...

Standard English... if only I wasn't so ignorant...

I thought so too... but i found this question in an geometric series section. EDIT: wait there isnt..

the original question is to find the first 10 terms of this series [(2^n)+(2n-1)] but I am having trouble finding the common ratio as the first 3 numbers are 3,7,13.. Don't judge me, I only slept for 2 hours

lolwut :L

haha yea i know but perms and comb are usually worth around 1 or 2 marks and they are pretty generic, circle geometry on the other hand.... worth alot more...

you can get 99.95 atar for any subjects, you just have work extremely hard and keep up your ranks

2U: whole of series and applications, I have 7 exercises of this and I'm trying my best to work through it, and possibly probability 3U: circle geometry and perms and combs, thank god these are only prelim topics

UNSW =D with a bachelor in computer science and science what about you?

same i cant stand English or any humanity subjects... except geography -.- but I do believe English should be compulsory, but not in the best of ten units T_T

That awkward moment when you burn out on first day term 1...

I'm only aiming for 90+ :L i'm not sure if I can make it :cry: what about you? I just get my textbooks off the publishers websites or buy it off some friends. Also what subjects you doing?

Mostly relaxing :L I've completely cleaned up my bedroom from all the prelim worksheet and threw them out, and brought a couple of new textbooks as well, and started writing up my physics notes (: Trololo I realised we made similar threads at exactly the same time

It has been 1 and a half weeks since school ended for public high school students. So I'm curious have you all relaxed for 1 and a half weeks or are you doing some little work like I have? Or are you guys planning to study hard after new years? And if any past HSC students viewing this...

You are awesome (Y). God why is our school so weird. -.- Today for our chemistry prac exam we had students sticky tape sheets of paper on to the exam because there wasnt enough room to write down the entire essay.

There are 4 tasks, the last one that was cut off is the trials I go to a school ranked around 190s -.- which is annoying because 5 years ago it was ranked around 130-140 -.- and all the good teachers retired -.- and nope our class strictly followed the year 11 course,

nope, see the updated post~

I'm not too sure, my head teacher told us at the beginning of the year that our prelim mark will be 10% of our hsc, but my own teacher said she was kidding around and that our marks wouldn't affect anything
