For the modules that require additional texts, do u guys write big definable chunks on each of the texts or do u blend it into ur essay? I've heard the good essays do integrate each of the text into the essay instead of writing a paragraph on each. Which do u guys do? and for the ones...

i still dont see it :(

of course :) maths isnt real anyway! thats y we have complex but do u's see anything wrong? i bet its something real obvious staring us in the face. however, i cant see it :(

apart from that typo, can any1 see a PROPER error?

wats ur problem today? i made a little typo, and ur still goin on bout it! ease up man! apart from forgetting to add >=, how else have i been incompetent in this area? well sorrry, if i cannot add inequalities!

firstly to estel..................it was a typo. i meant >=2!! and to dawso..... wat methods did u use? i racked my brains to think of those 2....lol u must b a genius if u can think of other legitimate methods :)

no. i got it from the arithmetic-geometric inequality. lemme show u how... (a+b)^2>=4ab (this is the inequality) Leave a as is....Sub b=1/a, therefore (a+1/a)^2>=4(a)(1/a) (a+1/a)^2>=4 (a+1/a)>=2 Same for b and c, So (a+1/a)+(b+1/b)+(c+1/c)>=2+2+2>=6!

but how does expressing it like that get any closer to a numerical answer?

i forgot to write it is greater or equal to 6 (a+1/a+b+1/b+c+1/c >=6) this is from (a+1/a)^2>=4 therefore (a+1/a)>=2

Ok, this is from the cambridge book from harder 3 unit chapter. question is: Show that: 1/a + 1/b + 1/c >= 9 Condition is if a+b+c=1. (a+b+c)(1/a+1/b+1/c) >= 9(a+b+c) >= 9 when u multiply both sides by (a+b+c), LHS = 1+1+1+ (b/a+a/b) +...

right u r ngai :) well put

like each element has its own frequency of vibration. so if the black body or cavity oscillators or atomic oscillators or watever they r called vibrate with so many frequencies, shouldnt they be composed of many different elements?

right u r ngai :) well put

i think putting it as @$%/% would work. However, for the 2nd method that u stated, u need to get it back into the form ax^3+bx^2+cx+d, dont u? i dont think all subsitutions of x can get back into that form, especially if u sub x=cube root of (x-1)

r all the atoms of the same element or not? they wouldnt be, would they, coz then there wouldnt be that many frequencies

ok thx, do u know the cause of blackbody radiation? something to do with oscillators or something

but how come the black body curve (intensity vs frequency) is a continuous curve over all frequencies?

hey archman, wat did u get for maths HSC?

how come urs got sent to u? mine got sent to the school, and my teachers opened it and stuff already b4 me

some1 got full marks?? for the AMC Maths Comp? Damn! wat a genius
