acmilan ur a bloody GENIUS!

what kind of question would Euler's formula make easier? can you post an e.g. plz

but it doesn't say that the tangent lies on the hyperbole at y=2

these are raw marks; '95 - 113 '96 - 111 '97 - 116 '98 - 114

what 2 are u saying are the same, the 2 S's in MISS or the 2 I's left over?

yeah 10char

u use the chain rule consider y=25(1 - t/60)2 let u = 1 - t/60 then y=25u2 you're trying to find dy/dt right? dy/dt=(dy/du).(du/dt) now y=25u2 so dy/du=50u or = 50(1-t/60) as u = 1 - t/60 and u = 1 - t/60 so du/dt = -1/60 (this is because t/60 is same as (1/60) x...

have you tried the tempest FAQ >>http://community.boredofstudies.org/showthread.php?t=66654 ?

initially the kid's weight is 274N (from W=mg), i.e. 294=GMm/r2 where M=mass of earth, m=kids mass. for (b) the mass of the planet triples so the new weght, W = G3Mm/2 we know from before that GMm/r2 = 294, hence the new weight = 3x294=882

yeah thats what the 'G' stands for, but u dont really need to sub it in, i just did it algebraically.

have u tried using this??>>http://www.boredofstudies.org/moderate.php

i used G=6.67x10^-11

just take out the "]" at the end of the link and it will work

u mean for question (b) u can say it increases, yeah?

the initial weight of the kid is 30x9.8=294N using newtons formula F=GMm/r2 initially this equalls 294N (a) if 'r' is tripled, sub that in to the formula and u'll get 1/9 of the original, that is 32.67N. (b) same concept but sub in M as 3M, so u'll get 882N

solutions for 2000 paper are in the resources section

hey, could u please send me the extended response and standards packages. thnks

any chance of a pic dat we can read?

yeah ur right, silly me, i'll change it. den dat gives 4/7 but that ain't right so wtf?

ok here's how i did it; for A at start not at end there are 7 spaces to be filled for the 1st space it has to be 1 of the A's so 3/7 the last space can be filled by any of the remaining letters except the A's so 4/6 so total probability for A at start not at end is 3/7.4/6=2/7 you...
