godlingkmh: preferably. i don't even know l'hospital yet. we're barely getting into derivatives.
japstaranybody can answer my question
kmhgodling : you could rewrite sqrt(x^2+2x) as a power series
standrlieven: the calculation that the documentary gives results in 1 "Jesus family" in 600,000 families. they multiply this by a sample size of 1000 tombs.
evilgeekgodling: what limit are you trying to evaluate?
japstarA certain tank can be filled by two pipes in 80 minutes. The larger pipe by itself can fill the tank in two hours less than the smaller pipe by itself.How long does each pipe take to fill the tank on its own?
godlingevilgeek: lim x->-inf (x+sqrt(x^2+2x))
evilgeekthat clearly diverges.
lievenjapstar: show us your work.
godlingmaybe it's clear to you. :)
evilgeekx+sqrt(x^2+2x) >= x.
kmhevilgeek : it does not
evilgeek : limit is -1
standrlieven: the calculation from the documentary does not address the actual population of the region of Jerusalem at that time period.
actiongodling looks up "diverge"
godlinglooks up "diverge"
evilgeekkmh: dude, it's positive.
kmhevilgeek : note x->-oo
evilgeekoh, i see.
TRWBWwell there is also the implicit differentiation where you find dy/dx based on f(x,y)=0
kmhmagnushc : look at all sets that have exatly {1} in common, all sets that have exactly {2} in common, all that have exactly {1,2} in common and those which have nothing in common
thermoplyae started giving you the {1} in common case
magnushcokey
thermoplyaenothing <-> neither 1 nor 2
kmhnor {1,2}
ah yes
so empty intersection regarding the relation, i.e. they are allowed to have 3 or 4 in common
probably easier this was {1} in common, {2} in common, {1,2} in common, the rest
magnushcahha, think i get it
kmhwas =way
TRWBWmagnushc: if you think you get it then you get it
magnushcyeah ;)
kmhso go and get it all :)
actually in my experience the mathematical thought process is full of "almost got it" ...
aah now i get - hmm wait - right i need to consider that, now it is fine - darn 1 sec - maybe if I - oh well ...
:)
magnushchehe, point
thermoplyaeI don't think there's much of a gray area on this problem specifically though
If it hasn't clicked all the way, then it probably hasn't clicked at all
kmhmaybe
or rather hopefully :)
