Polytope | he's asked to use the derivative, so he should show that the derivative takes both positive and negative values |

appletizer | CicciuxLa, maybe upon retrospection it seemed simple :) but i can still remember struggling lol |

Polytope | although that's an overly complicated way to do it |

Eclipsor | everything in retrospect seems simple :D |

CicciuxLa | nope, I really enjoyed calculus... |

appletizer | true :] |

WILDSTYLE | Hi. |

CicciuxLa | anyway, using the derivative you would just get (cos(3x+2))' = -3 sin (3x+2) |

chino | teach me something |

WILDSTYLE | chino, the rationals are dense in the reals. |

chino | que passa ? |

CicciuxLa | and -3 sin (3x+2) and -3 sin (3x+2+2PI) have different signs, therefore it's not strictly monotoni. |

chino | go easy |

WILDSTYLE | No. |

CicciuxLa | chino: nada, por que? estamos tratando de responder las preguntas cuya respuesta conocemos, y preguntar o que no sabemos. what do you mean by that WILDSTYLE ? |

WILDSTYLE | I was addressing chino vis a vis his request that I 'go easy'. |

chino | CicciuxLa: estas ablando mucho rapido... que quer desir "cuya" ... "sua" ? |

CicciuxLa | I meant about the rationals being dense in the reals. chino, you mean Hablando. |

WILDSTYLE | You can always find another one between any two in |R. |

CicciuxLa | and cuya means whose oh... I see. |

chino | "respuesta" you mean "requesta" ? ahhh i see your trying to respond to questions that you are familiar with |

CicciuxLa | something along those lines, yeah. |

chino | yea i dont really know spanish |

appletizer | habla usted anglo? :) |

chino | wtf is anglo ? |

EdBoy | anglo? wtf? |

chino | voce e un pocado maluco |

EdBoy | anyway |

Eclipsor | ok, so now its the same question with x^3-6x^2+12x, I take the derivative 3x^2-12x+12 and since that's a quadratic function it's not monotonic since it isn't always increasing/decreasing? and then it doesn't have an inverse function because of that also? |

EdBoy | ((sum of 1 to infinity of (1/n)^(1/n))-1)^2 = 2 |
