 Smacs Hey can someone lead me to the formular for compund interest. purplepenguins it's like Pe^(rt) Eclipsor yupPrincipal*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 oneP(1+r/t)^nt purplepenguins that is the infinitely compounded rate TRWBW um, drop the t Eclipsor thats for none infinitely I thinkyou 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 deriveSmacs: so a 5 percent annual rate compounded monthly would be from principle p yield p*(1+.05/12)^12 Smacs Yes thanksSo 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 fileonly 300kb thoughstill 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
