so TP's still allow duplex communication as the pairs can recieve data via the uplink and the downlink at the same time because there are 2 different pairs used yeh? and ive had written down - TP = 60Kbps (is this a generalisaton or is this outdated info which doesnt consider Cat5+> Because when...

alritey just to clarify a twisted pair cable usually contains the 4 pairs of twisted copper wires. This allows a TP cable to be used in full-duplex transmission as 2 pairs for recieveing data from the central node and the other 2 for sending data yeh? so what i deduced here is that it is the...

why are u not getting over 90 if ur doing that much? im expecting over 80 and i do about 2 hrs every second day... u should be blitzing it...

2004 HSC Q9 a ii so r is -tan^2(theta) for what values of theta in the interval -pi/2 < theta < pi/2 does the limiting sum of the series exist. i get the working up upto here -1< tan^2(theta) < 1 then i dont get this... "since tan^2(theta) > 0, only need to solve tan^(theta) <1 :SSSSSS and then...

when im doing sine rule and do sinx = (12sin20/19) to get 0.21... is it because it is less than 0 we do shift sine? i dont undersatnd when we have to use shift sine and when not to

are u all refering to just proving its a max or a min? or like testing POI so that the sign changes

ahk fairs enuf hows about when we do that for maximum and minimum volumes...what does x'=o for?

so i know we get x' = 0, solve for x, sub this x in x'' and then if >0 is min n what not. i remember a question that said "give reasoning" as to why you are doing stuff - why do we get x' = 0 and do the succeeding steps? what does x' give us and what not like i know x' is gradient for a curve...

wb water loss?

the first player to win 2 sets wins the match. notice some1 has won either way over 3 sets

the game can only last 3 look at a tree diagram...by the third set some1 has already won 2 sets

hah same as mine lol what we doing wrong aha

aha diversity! did u use 14/12 = whatever (dont have calc) for the rate for each month and then do it for 300 months?

i) 2 sets = P(nicole wins) + P(mariana wins) = (.49) + (.147) = .58 ii) now after they have played 3 sets some1 has to have won at least twice... = P(.49) + P(.147) + P(.147) = 98/125 ii) P = 1- (98/125) = 27/125 thats how i understood it anyways same answers as above

lol i tried i) 598.82 ii) 663.19 i dont think there right tho as i do 598.82 X 300 mnths = some number like 180,000 aha and i dont think youd pay that much for a 50,000 loan but the rate is quiet high so i dno if u want working i could aha

do u rekon in an exam it would be worth to write for the method i) place bottle of distilled water and a bottle of softdrink (unopened) on scales and weighed each ii) placed each in a water bath and heated on low, re-measuring the softdrink untill there appeared to be no mass change (took water...

So if a hub was used on building A's network, and message was desired to be send between two PC's in building A, would the bridge just not forward it to those in Building B as it would clog up the network? so can the the bridge inspect the header address and if the designated computer isnt in...

thanks guys

when we are dividing 6 by root6 i dont understand how we can just multiply both num/denominator by root6 dont we normally change the sign when rationalising a surd...

when ozone is depleted, it it exothermic? and what effect does CFC's or ozone depletion or whatever have on global warming? i cant find this anywhere but im thinking it has something to do with a reaction being exothermic? or that as there is less ozone the UV comes and heats up earth more and...
