mbot | bsmntbombdood: asin[1/Sqrt[2]] |

bsmntbombdood | helpful. % asin[Sqrt[.5]] //FullSimplify |

mbot | bsmntbombdood: asin[0.7071067811865476] |

Manyfold | yes he is indeed |

bsmntbombdood | % Asin[Sqrt[.5]] //FullSimplify |

mbot | bsmntbombdood: Asin[0.7071067811865476] |

bsmntbombdood | what's the function for arc sine? |

Cale | ArcSin |

bsmntbombdood | % ArcSin[Sqrt[.5]] //FullSimplify |

mbot | bsmntbombdood: 0.7853981633974484 |

Cale | % ArcSin[Sqrt[1/2]] |

mbot | Cale: Pi/4 |

bsmntbombdood | much better |

Cale | and that's why you don't use decimals with mathematica unless you really know you want an approximation :) |

Manyfold | Cale: how good are with PDE's? |

bsmntbombdood | Well, I thought it wasn't going to be able to give me an exact answer |

Cale | I don't know anything about PDE's. |

Manyfold | :( well you surely know \partial |

flaminguican | _llll_: I'm not seeing how writing the equation in terms of tangent helps |

bsmntbombdood | flaminguican: what's wrong with my solution? |

_llll_ | what did you end up with? |

flaminguican | 0 |

_llll_ | ? you should end up with an equation... |

flaminguican | meh, but I must be doing something wrong. Let me rework some stuff |

bsmntbombdood | oh, right % ArcTan[1] |

mbot | bsmntbombdood: Pi/4 |

bsmntbombdood | yep sin(x) = tan(x)cos(x) |

flaminguican | Hm, okay, I see where you guys are going with the tangent thing now. But that means I must have messed up a sign somewhere farther back, because it gives me the correct answer with the incorrect sign :/ Alright, well thanks for all of the help again. I'll figure out the rest from here :) |

kmh | hmmm what's the problem ? |

bsmntbombdood | he made me curious |
