y= cos (ln (x) + 1) y'= -1/x (-sin (ln(x) + 1)) = [sin (ln (x) + 1)]/x enough calculus (c) A chessboard has 32 black squares and 32 white squares. Tanya chooses three different squares at random. (i) What is the probability that Tanya chooses three white squares? (ii) What is the probability...

yes you're right, from the 2002 notes: i got confused with another module where people stuffed because it asked for a specific text.

you've got to finish it off.

Sn = n/2 [2a + (n-1)d] so S10 = 5 [84 - 45] = 195 x^3 - 27 = (x-3)(x^2 +3x + 9) solve for x. (2e^2x) - e^x = 0

i say the chances are very very low because alot of kids got stuffed in that 2002 question.

How many are you preparing for? how many do you think we'll be asked to refer to in the exam? how many were you asked to refer to in your trial? cheers!

are you doing the paper in the 3hr time and in a quiet distraction free environment?

well i argue Stalinism started to develop around 1922ish when Lenin was basically a ghost. Dont be fooled by the question, its asking about the development of Stalinism. i'd talk about the success of the Cheka in the civil war, Stalin's political cunning and his close ties with the head of the...

WOW!:uhhuh: i found 2007 really really easy. probably because i didn't do any work in year 11 but worked my arse off in calculus. bring on a 2009 paper with calculus for 9 and 10.

what do you specifically want do know about the cash rate? [im guessing how the RBA manipulates it?] you dont need to know current statistics but DEFINATELY know current trends and proportions. e.g. know the trend in our CAD as a % of GDP over the past few years. be aware the cash rate has...

8 DAYS. can't wait to get english outta the way!

SUCCESS ONE hsc book. but if your like me and have the one that only goes to 2006, [and used the answers to the 2008 from the the resource section] my only solution would be.. borrow one from a friend or ask your teacher to mark it.

ah! THANK YOU! i was waiting for some proof rather than "you just round up." so i should have treated January as the 0th month, and december as the 11th. 0 < January <1/12 1/12< February < 2/12 2/12 < March < 3/12 3/12 < April < 4/12 4/12 < May < 5/12 5/12 < June < 6/12 6/12 < July < 7/12...

i know that you should round up normally. but the wording of the question makes me think otherwise. usually the question would ask AFTER [or by. etc] what month are there 4000mil phones. but this Q asking DURING which month does N reach 4000mil. and you cannot argue that N reaches 4000 in...

yes i see where you are coming from. 2008 - 1st year 2009 - 2nd year 2010 - 3rd year but my point still remains that 4000mil was reached after 2.88 [2years 10months] years.... which is October 2010. what makes you say it occurs in November and not October?

because i am slow! my maths teachers have taught me so that i basically write down EVERY line of working, and it takes me forever to do plane geometry and trig. JUST GOT 113/120 for 2007 HSC! :drink: that's gotta be a mid to high band 6?!

now. i have an issue with this question. it is Q8(a) from the 2007 HSC. specifically the issue is in part (ii). the question says "According to the model, during which month and year will the number of mobile phones in use first exceed 4000 million?" which is fine. we find t = 2.88...

it was far more difficult than 2008! 2008 was far to easy.

this is my personal situation. i will be living at home and working full time from november 2009 to january 2010. from Jan 2010 to Jan 2011 i will be living in Norway. then when i get back i will be moving out for Uni. im sure you will be fine moving away, yes it is a massive step, but im...
