CicciuxLaobviously, otherwise you wouldn't ask that. Mathematicians love to classify numbers...
chinoyea i figured you guys just like to play around with properties of numbers and equations
CicciuxLathey even have 'perfect' numbers, you know... funny ones those are... a bit annoying since nobody seems to know how many there are...
chinowhy are they perfect?
TRWBWchino: the aren't, it's sort of an ironic name, like a sarcastic, "he's so perfect"
http://en.wikipedia.org/wiki/Perfect_number
KasadkadCicciuxLa: there are infinitely many
Eclipsorwell, have you counted to infinity, Kasadkad ?
CicciuxLaKasadkad: i have seen no proof yet.
KasadkadHmm
Okay, I guess that's not proved
chinoisn't the multiplicative inverse a bit wierd ?
KasadkadI thought it was like every number of some form is perfect, but it's every even perfect number is of some form
But you know, I don't like to label numbers
chinoyou know "a/b=a(1/b)"
KasadkadI have irrational and composite friends
Steve|OfficeThe question is how many primitive elements are there in F_{2^6}. To be primitive they must have order 63. phi(63)=24 so my guess is there are 23 elements of order 63. Is that even remotely reasonable?
chinowhere b!=0
KasadkadSteve|Office: It's 24
chinotell me that isn't weird ?
Kasadkadphi(d) is the number of elements in a cyclic group with order d (where d divides the order of the group)
chino: ?
chinowha t?
Steve|OfficeOkay. I really wish I knew this stuff.
KasadkadMultiplicative inverses aren't weird
Everyone likes second chance
You do something, you want to be able to undo it
chinoi wonna know wht the multiplicative inverse works
the 2nd side of the equal size appears to be how you would get the percentage of a number
Steve|OfficeHuh?
chinohow the hell does that correlate to the result of deviding
Eclipsorugh
my book doesnt cover this problem at all
chinowhat problem ?
CicciuxLawhat are you talking about chino?
Polytopeby the way, phi(63) = 36
EclipsorUse the derivative to determine whether the function f(x)=cos(3x/2) is strictly monotonic on its entire domain and whether it has an inverse function.
what's strictly monotonic?
and how would that help me find if it has an inverse
CicciuxLawhat is the domain?
