1/2(1+i^2n)?

dude thats a 4u perms and comb question. why the hell are u posting this in the ext1 marathon this is from the sceggs darlinghurst 2009 4u paper q6 seriously this thread is just becoming an ext2 marathon with easy-med ext2 questions

mx1 : i'm just glad that they did permutations last year. so chances are they might not do it again. I really do hope its a projectile mx2: rofl it doesnt really matter what they throw at me. i just hope conics are easy and very little harder 3u.

if it wasnt for school i would never of watched the lion king or mulan. I think it was year 7/8 or even primary school. those muck up days where teachers cant be stuffed teaching and give u a video to watch and answer some stupid questions.

WOOHOOO Im probably expecting like 85-90 for hsc since theyre way harder than trials. Wait this is raw marks right? Otherwise with scaling id get 99.95 (for 4u) for sure. if i get around 85 that means ill be doing decent... right.......? holy shit that means like 70% goes to like high 90s? i...

as much i know that i could of done so much better if i didnt procrastinate as much or had more time, i just wanna get this shit over and done with. Never wanna experience the HSC ever again.

since no one posted a question heres a fun one: <a href="http://www.codecogs.com/eqnedit.php?latex=\int_{-1}^{1}\frac{1}{x^2} dx" target="_blank"><img src="http://latex.codecogs.com/gif.latex?\int_{-1}^{1}\frac{1}{x^2} dx" title="\int_{-1}^{1}\frac{1}{x^2} dx" /></a>

thats a 4u q1 question. but nonetheless its still adequate for 3u students

shit forgot question

i found the end parts of q6 actually harder than most of q7. but i do think that last years q7 was easier compared to other years. q7 difficulty in 3u isnt really consistent anyways

Both those videos didnt work for me :( :(

irrelevant but saw this when looking at the courses that allow calculators Soooooo unfair.

The HSC will NEVER ask that directly. Im pretty sure thats not in the syllabus. So u shouldnt need to worry about it. You'll only ever use it in an essay, and thats only if the essay question allows to u write about it. Honestly, i have no idea what it is lol. How does the National Competition...

i wanna know about the compass thing too. if u look at the bos sample answers for the 2009 ext 2 paper, they didnt use a compass :S

Wow 38... Your a God at eco. Im expecting a state rank dude. I've neglected eco pretty heavily since trials because im failing so hard at english. havent even written one essay for eco yet.

lol its: i

what is the square root of (-1)

HAHAHA just tattoo all your quotes onto ur hand. Theres no way they can make you cover that up. unless they expect u to write with gloves. Or better, just tattoo quotes onto ur face to help your friend sitting next to u "hypothetically"
