1) think 3unit question 2) a) P(at least 1) = 1 - P(0) = 1 - 4/14 b) [7/14] x [6/13] c) = P(BR) + P(BG) + P(RG) = ([3/14] x [4/13]) + ([3/14] x [7/13]) + ([4/14] x [7/13]) d) 0 3) P(noone picks their name) = P(of the first person not getting their name, AND the second person not getting their...

you must remember that the 'new' NSW HSC was introduced in 2001 - with new formats and everything, so just like when anything is newly tested, adjustments need to be made. i'd say the E4 cutoff this year would be around the low to mid 60's out of 84.

thanks for the upload finally a 5 mark question!

you mean by two-day full-time timetable?

dun forget bubbilicious too:)

based on all this information given, id say food tech.

i used to sleep about 10

seriously guys, its soo much easier to sketch the graphs when you sketch y=sin(180+x), the curve shifts 180 degrees to the left, so in effect, you get the curve y=-sinx and y=sin(-x) = -sinx so sin(360-x) = -sin(360+x) and when thats sketched, its the same as -sinx since the sinx curve repeats...

while that may be true, im guessing most of that 2% is part of the business faculty

well at least you didnt do it in your Extension 1 2007 HSC exam

the best way to study is to start low (ie. half - 1 hour a day) for term 4, then increase it to about 2-3 hours a day before the trials, since term 4 stuff is generally easier but the issue is actually starting, and sticking to it, because the moment you stop your schedule, its so hard to get...

this thread has reached over 10,000 posts.... but is there a definitive answer to the question "Does God exist??"

*double post* our tutor said you should get ur results on webct on fri week 8

what do you mean by "manage to do it" if you mean study 5-6 hours, no.

if you wanna know how its derived... you use the following 3unit formula: cos(a-b) = cosacosb + sinasinb so with a=90, b=theta: cos(90 - theta) = cos90costheta + sin90sintheta = 0 + sintheta = sintheta try it in your calculator... it sersly works

low 70s% raw would be E4, so im guessing 65% would be aligned to about 80-85% for 4unit

i sersly wish i could.........................:spam:

Re: maths help needed ASAP you don't need a graph drawer to sketch y = tan(x-60)... it just the normal tan curve shifted right 60 degrees..... unless......

ON TOPIC: apparently the average is 60-65%

oh man im bored.. 2.Express x^6 + 2x^4 + 2x^2 +1 as a product of three quadratic factors. let u = x^2 so your P(x) = u^3 + x^2 + u + 1 note that u = -1 is a root of P(x) factorising that yields P(x) = (u+1)(u^2+u+1) implying that P(x) = (x^2+1)(x^4+x^2+1)
