godling | kmh: preferably. i don't even know l'hospital yet. we're barely getting into derivatives. |

japstar | anybody can answer my question |

kmh | godling : you could rewrite sqrt(x^2+2x) as a power series |

standr | lieven: 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. |

evilgeek | godling: what limit are you trying to evaluate? |

japstar | A 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? |

godling | evilgeek: lim x->-inf (x+sqrt(x^2+2x)) |

evilgeek | that clearly diverges. |

lieven | japstar: show us your work. |

godling | maybe it's clear to you. :) |

evilgeek | x+sqrt(x^2+2x) >= x. |

kmh | evilgeek : it does not evilgeek : limit is -1 |

standr | lieven: the calculation from the documentary does not address the actual population of the region of Jerusalem at that time period. |

action | godling looks up "diverge" |

godling | looks up "diverge" |

evilgeek | kmh: dude, it's positive. |

kmh | evilgeek : note x->-oo |

evilgeek | oh, i see. |

TRWBW | well there is also the implicit differentiation where you find dy/dx based on f(x,y)=0 |

kmh | magnushc : 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 |

magnushc | okey |

thermoplyae | nothing <-> neither 1 nor 2 |

kmh | nor {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 |

magnushc | ahha, think i get it |

kmh | was =way |

TRWBW | magnushc: if you think you get it then you get it |

magnushc | yeah ;) |

kmh | so 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 ... :) |

magnushc | hehe, point |

thermoplyae | I 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 |

kmh | maybe or rather hopefully :) |
