#math
<Pests> cosecant
<JohnFlux> oh inverse sine :-)
<Pests> ;)
<Pests> If I say I hate math in #math do I die? =/
<Trixsey> yes
<Pests> :(
<Trixsey> I would cut your belly wide open
<Trixsey> and then eat your guts!
<JohnFlux> the bot is triggered for it
<Pests> really now?
<Pests> ;-)
<Trixsey> no :)
<Trixsey> hahaha
<Trixsey> aww
<Pests> I figured =P
<JohnFlux> okay so you have x * sin^-1(x) * cos(x) / sin(x)
<JohnFlux> Pests: right?
<Pests> John: Um? :)
<JohnFlux> no wait sorry
<JohnFlux> cot is inverse tan
<JohnFlux> heh
<JohnFlux> no i have that right
<JohnFlux> Pests: so that is: x * cos(x) / sin^2(x)
<JohnFlux> Pests: right?
<JohnFlux> Pests: you want to now integrate that
<JohnFlux> Pests: still there? ;-)
<Pests> Sorry, trying to keep up. ;)
<JohnFlux> hehe
<JohnFlux> I just turned your abbreviations into something more sensible :-O
<JohnFlux> csc(x) is 1/sin(x)
<JohnFlux> and cot(x) is cos(x)/sin(x)
<Pests> yeah
<Pests> I see it now.
<Kasadkad> csc, cot, and sec are all quite standard
<Kasadkad> And don't call csc the inverse sine...
<JohnFlux> Kasadkad: yeah that's my bad
<JohnFlux> Kasadkad: i know cot and sec, but I hadn't heard of csc heh
<Trixsey> how do I do *not* in matlab?
<Trixsey> ~?
<Trixsey> if(x~=y)?
<Trixsey> if(x~y)?

<EvilTerran> ok, i have the relation N(1) = 1, N(n) = sum (i from 1 to n-1) of N(i)*N(n-i). I've shown numerically that it limits towards an exponential function (N(n)/N(n-1) tends to 4 from below), but how would i prove it?
<Kasadkad> EvilTerran: It's possible to find an explicit formula
<EvilTerran> I've had no success finding an explicit formula. do you have any suggestions for Cunning Tricks?
<Kasadkad> generating functions
<EvilTerran> I've also tried algebraically finding the limit of N(n)/N(n-1), but it's horrible. I've also tried strong induction to prove it's always <4^n, but that didn't work
<Kasadkad> Do you know how generating functions work/
<EvilTerran> not really, no.
<Kasadkad> Ah
