Does anyone know how to take the inverse Laplace transform of
Y(s)= 4/(s+(3+J6)) + -4/(s+(3-J6)) 6/14/2006 5:06:00 PM |

I'll get you started...
4(s+(3-J6)) - 4(s+(3+J6) The whole thing divided by (s+(3+J6))(s+(3-J6))
= -j48/((s+3)^2 + 6^2) Take the Laplace transform of that.

hahah.
I can tell my job doesn't require any of this stuff. I just called it "lap lace" and was like wtf is that 6/14/2006 11:20:51 PM |

fucking laplace and his transforms... Him and Fourier too.... 6/15/2006 1:53:29 AM |

if we used i we'd get it confused with current. 6/15/2006 1:56:10 AM |

I'm more of a math person than engineer and I don't see how two lowercase letters can piss so many people off. Next to that, pronouncing Euler (you-ler and oil-er). 6/15/2006 8:04:26 AM |

im so used to seeing j, ill often get confused when i see an imaginary i.
i have to do fourier and laplace stuff every day. who ever would've thunk that power engineering would require that stuff 6/15/2006 11:59:03 AM |

kidding aside, the whole Laplace transform idea is really amazing. How in the world did he think up that stuff. It's really bizarre compared to other math, maybe it's just a French thing... 6/15/2006 12:48:51 PM |

Note that traces of mercury in a hair sample from Newton was something like 40x the safe amount. Makes you think, hm? 6/16/2006 1:09:56 AM |

ya, maybe the "safe" level of mercury is not correct. 6/16/2006 2:24:19 PM |
