hrmm. really wasnt thinking well during exam i suppose. now i feel even stupider than i did when i walked out of the room ^^ thanks all.

right i broke my brain trying to answer these in my trial. so i thought they might be interesting to see other approaches. a) prove (cos x) - 1 + (x^2/2) > 0 i stared that this for a good minute or so then said "buggrit" and moved on. b) <i>refer to attachment for diagram. pardon my...

mmm i was under the impression that you could take the anti-differential of a definite integral under certain conditions, like if the function was continous over the interval between the limits but discontinous at one of them? in this case you could do this from 0->1 which would give you a...

you wouldnt. u can use any of the 3 unit only stuff to answer 2 unit questions. same goes for 4 unit to answer 3 unit, etc etc. hell, u could probly break out some extra-curricular stuff if u really felt it necessary. hsc markers will go out of their way to validate your work, they're trying to...

hehe slide rule has what is probly the answer they would be looking for - but u asked for the chang eof base rule, so its there.

the integral exists but i would think only as a limit, that is the value of 2 is the limiting value of the area function -1/x ?? meh i dunno

wish i could have ;o sounds like fun.

change of base rule is: log_a x = (log_b x)/(log_b a) to do this on your calculator, u first have to change to either base 10 or base e, then evaluate. gl2u ^^

hmmm my trial 2moro ... im not overly concerned. i missed 7 weeks of the course with illness which included the consumer arithmetic and series stuff, but its pretty basic. now that i've said that, im going to fail. miserably. damnit, hate jinxing myself like this.

syncrotrons are cyclic accelerators. they accelerate particles in circular motion. cyclotrons are also cyclic accelerators. simple answer :]

well it was essentially one of the key concepts in developing the standard model of matter, and several branches of associated quantum physics. this led into things like the manhattan project (on the syllabus) and the advent of the nuclear age - which had a profound impact on the world in...

i have only one lesson a week of 4u but class of 2... so we've finished all bar resisted motion. next week we do that, then after that its revision all the way. in my 3u class of about 15, we finished the course week 8 last term, and now i tend to do most of my 4u stuff in the 7 3u periods i...

wow this book doesnt suck - its actually extremely well written...well that is to say it is very intellectually and cleverly written. ondaatje has an interesting grasp on imagery that i quite enjoy, he also writes in a "complete" style ie not one word wasted - not very precise but the only word...

ridiculous that your parents would put the responsibility for your BROTHERS maths mark in YOUR hands. . . way to begin some severe mental issues for the both of you in later life :P in all seriousness, im not really in a position to comment considering that i do basically no revision or study...

mmm i always assumed values as being ideals of the author being expressed through the text, not the values of the characters in the text itself. i think that one must be very careful in looking at values vs themes - to me values implies a greater depth of "message" ie a more definite opinion. i...
