Smacs | Hey can someone lead me to the formular for compund interest. |

purplepenguins | it's like Pe^(rt) |

Eclipsor | yup Principal*e^(rate*time) |

TRWBW | Smacs: compound is vague. infinitely compounded? |

Eclipsor | oh crud |

purplepenguins | P being the principal, r is the interest rate as a decimal, and t is time |

Smacs | This is what I want to have a formular to work out |

Eclipsor | forgot the other one P(1+r/t)^nt |

purplepenguins | that is the infinitely compounded rate |

TRWBW | um, drop the t |

Eclipsor | thats for none infinitely I think you sure? |

Smacs | I have 10,000 which I want to ivest for 12 months, The interest rate is 6.8%, compunded monthly, calculated daily |

TRWBW | Eclipsor: i mean n |

Eclipsor | :\ |

TRWBW | Eclipsor: P*(1+r/n)^n compounds interest r n times |

Eclipsor | thats the one! |

TRWBW | Eclipsor: limit n->inf P*(1+r/n)^n=p*e^r is infinitely compounded interest |

Smacs | Whats n? |

TRWBW | Smacs: how many times you compound. |

Smacs | per year right? |

TRWBW | Smacs: it's actually the *definition* of compounding, not something you derive Smacs: so a 5 percent annual rate compounded monthly would be from principle p yield p*(1+.05/12)^12 |

Smacs | Yes thanks So to confirm the asnwer to my question is : 10701.5988 |

TRWBW | "The most powerful force in the universe is compound interest" - Albert Einstein |

Smacs | Can anyone confirm I got the correct answer? |

mdmkolbe|home | I want to double check my terminology. Is it correct to say that all latices are partially ordered sets, but only some partially ordered sets are latices? |

action | Eclipsor is addicted to graphs |

Eclipsor | is addicted to graphs :( I've been graphing runescape player population since last week :\ and by god, it's >.> interesting |

mdmkolbe|home | Eclipsor: link? |

Eclipsor | www.eclipsor.com/images/rsgraph/w126best.png <-- warning 40000x1000 file only 300kb though still need to do some touchups |

TRWBW | mdmkolbe|home: yes. take for example a set in which no two elements are comparable. mdmkolbe|home: trivially a poset, but not a lattice |
