<0> neato :-p
<1> % Integrate[Log[1-x]/x, {x, 0, 1}]
<2> int-e: -Pi^2/6
<0> mine didnt recognize pi :-p
<1> % (Integrate[(t^(-1/2))*(E^-t),{t,0,Infinity}])^2
<2> int-e: Pi
<0> good point :-)
<3> :(
<3> boring games
<4> What games?
<3> baldurs gate 2
<4> oh
<5> o_q
<6> when working with crypto code in cbc mode, is it bad practice to reuse the IV as the p***word salt?
<7> Cale, are you around?
<7> Does anyone ever heard about a real world usage for category theory (if there is one...)?
<8> have you tried google or wiki?
<9> the answer is yes
<9> if there is one, I'm sure someone has heard of it
<8> "does anyone ever heard"...
<9> oh, so that should be herd, not heard
<8> no that shouldnt be herd
<8> herd is one made up of cows
<9> yes
<7> GuestBlah, thanks
<10> exactly!
<9> herding cows about category theory
<8> god you're special
<11> Cale: I picked up that book you recommended for category theory.
<9> would you recommend herding them through it?
<7> |Steve|, wich book?
<11> Categories for the working Mathematitian.
<7> all Ive read about it seems much more like philosophy than math
<11> A friend of mine said that it's the "only category" book.
<7> |Steve|, hmmm... Uni lib has sample I will read it
<11> I've only made it to page 15 or so (and I left it in my office).
<11> They use things I've never studied as examples such as homology (no idea what that is) and Lie Algebras of Lie groups, again, no idea.
<12> |Steve|: That book rocks. I read it when I was too young to grasp the third chapter, but man, that book rocks.
<11> Good.
<12> I vaguely remember one of the titles is "Everything is a Kan Extension"
<12> Which was really humourous at the time. I still have no clue what a Kan Extension is, but the title is still around in my head.
<11> Yeah, I think that's the last chapter's title.
<12> I really should interlibrary that when I get back to school. Hmmm.
<11> % GCD[8,4]
<11> hmm
<2> |Steve|: 4
<11> Oh, that does work.
<11> % GCD[15n+6,7n+1]
<2> |Steve|: GCD[1 + 7*n, 6 + 15*n]
<11> Bah
<12> awww
<13> % ArcSin[2]
<2> gregerg: ArcSin[2]
<13> % Arcsin(2)
<2> gregerg: 2*Arcsin
<11> % ArcSin[1]
<2> |Steve|: Pi/2
<11> It apparently only works with reals.
<13> % quand est le bain dormir
<2> gregerg: bain*dormir*est*le*quand
<13> interesting
<11> Something about sleeping?
<13> i think I said "when is the bath to sleep
<13> "
<11> Interesting.
<13> i'm really good at conversational french speaking
<13> % Phi
<2> gregerg: Phi
<14> how do you get the composite function form of an equation?
<13> % life, the universe, and everything
<2> gregerg: $Failed
<13> aha!
<14> y = \!\(x\^\(1/3\)\/\(1 + x\^\(1/3\)\)\) do any of you guys know how to get a composite function form out of that?
<8> wtf

<8> ok stop that ****
<13> lol
<14> now that's accuracy :)
<8> no that's you being annoying
<8> me saying that is accuracy

<13> what the heck
<14> GoldenRatio is the constant
<13> why not just phi?
<14> phi is just a letter representing the golden ratio
<14> phi doesn't mean anything
<13> but same thing with pi
<14> Pi isn't a letter to my knowledge
<13> hmm
<13> thought it was
<14> maybe
<14> I might be wrong
<13> never joined a frat :P
<14> haha yeah
<14> you're right; it is a letter
<13> yeahg
<13> thought so
<13> not aware that anyone uses phi to represent anything else
<14> well it could be used as a variable name
<13> you'd have to run through a lot of variables to get to phi :/
<14> It wouldn't be a good choice, but it could be
<14> yeah
<14> I think it's because most people know it as the golden ratio, and not as phi.
<13> you're too big!
<14> hah
<8> wow and i thought conversations with fruitbag were dumb
<13> lol
<13> ruh roh
<15> Pi is a letter
<15> & it does sometimes have meanings other than 3.141..., e.g. Euler's function for estimating the number of primes less than a certain number, or capital Pi meaning product (like capital Sigma means sum)
<13> seems like Phi should also work in place of GoldenRation
<13> ok enough of math homework
<13> onto quake 3 homework
<16> anyone up for a logic question?
<17> go ... :)
<16> okay..... well.... given (P->Q)&(Q->R) |- (PvQ)->R
<17> ok ...
<16> i ***umed (P->Q)&(Q->R) and P, and did & elimination to get P->Q and Q->R
<16> and modus ponendo ponens of (p->q) to get Q
<17> wait just a sec: -> is implies & is and and v is or?
