srart | :-D |

sproingie | attrgetter can actually get multiple attributes at once it also has a __getattr__ method itself, but i can't see what it's used for er __getattribute__ that is |

srart | I'm working on the help implimentation of jython, operator doesn't have attrgetter implemented, and the call used is classes.sort(key=attrgetter('__module__', '__name__')) ,then some reflection type magic to call for '__doc__', eventually. that call is from C version |

zpertee | hello i have a formula that I need solved when I enter any real value for x. I've posted my formula at http://pastebin.ca/458773. I'm getting stuck any help appreciated |

riczho | zpertee: Taylor series? |

srart | zpertee: are you entering X on the left, and trying to get a taylor for it? |

riczho | zpertee: Looks like sin(x). |

zpertee | I'm trying to solve for sin using this formula |

srart | diffeq class? |

zpertee | precalc |

srart | what? big extra credit or is your school just nuts. |

riczho | Heh. |

zpertee | srart: extra credit. maybe I'll pass this way |

srart | do you have ANY code yet? |

riczho | So you want to create a function that takes the number of terms (or some maximum error) and return an estimate? |

zpertee | yes. i'm a newbie but I started trying to do a while loop to generate numbers but not sure If i was on the right track or not riczho: yes otherwise it would just go on forever |

srart | it's easy to find factorial examples all over the web. |

zpertee | I've found a factorial function already and it works |

riczho | OK, so since the nth derivative of sine cycles, you can easily know those. |

srart | where is your code dying? |

riczho | Then you just loop until abs(next term) is less than your maximum error. (Where each iteration adds the next term). |

CSWookie | Heneral channel policy, has always been no specific help for class work, btw. s/Heneral/General/ |

srart | hence the leading questions |

zpertee | CSWookie: ok. I'll just ask somewhere else |

riczho | Oh, sorry- I just started listening around here today. |

CSWookie | I just thought I'd mention it. |

srart | good learning for code, non CS specific. |

zpertee | is the overall feeling though that I should create a function to do this though |

CSWookie | zpertee: Probably. I'd look it up on wikipedia. |

zpertee | CSWookie: good old wikipedia |

CSWookie | They offer some fairly readable pseudocode for well-known functions. |

srart | zpertee: look at lambda and zip functions, build your factorials in a list, and your exponents the same way, then smoosh em together. |
