CicciuxLa | obviously, otherwise you wouldn't ask that. Mathematicians love to classify numbers... |

chino | yea i figured you guys just like to play around with properties of numbers and equations |

CicciuxLa | they even have 'perfect' numbers, you know... funny ones those are... a bit annoying since nobody seems to know how many there are... |

chino | why are they perfect? |

TRWBW | chino: the aren't, it's sort of an ironic name, like a sarcastic, "he's so perfect" http://en.wikipedia.org/wiki/Perfect_number |

Kasadkad | CicciuxLa: there are infinitely many |

Eclipsor | well, have you counted to infinity, Kasadkad ? |

CicciuxLa | Kasadkad: i have seen no proof yet. |

Kasadkad | Hmm Okay, I guess that's not proved |

chino | isn't the multiplicative inverse a bit wierd ? |

Kasadkad | I 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 |

chino | you know "a/b=a(1/b)" |

Kasadkad | I have irrational and composite friends |

Steve|Office | The 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? |

chino | where b!=0 |

Kasadkad | Steve|Office: It's 24 |

chino | tell me that isn't weird ? |

Kasadkad | phi(d) is the number of elements in a cyclic group with order d (where d divides the order of the group) chino: ? |

chino | wha t? |

Steve|Office | Okay. I really wish I knew this stuff. |

Kasadkad | Multiplicative inverses aren't weird Everyone likes second chance You do something, you want to be able to undo it |

chino | i 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|Office | Huh? |

chino | how the hell does that correlate to the result of deviding |

Eclipsor | ugh my book doesnt cover this problem at all |

chino | what problem ? |

CicciuxLa | what are you talking about chino? |

Polytope | by the way, phi(63) = 36 |

Eclipsor | Use 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 |

CicciuxLa | what is the domain? |
