SmacsHey can someone lead me to the formular for compund interest.
purplepenguinsit's like Pe^(rt)
Eclipsoryup
Principal*e^(rate*time)
TRWBWSmacs: compound is vague. infinitely compounded?
Eclipsoroh crud
purplepenguinsP being the principal, r is the interest rate as a decimal, and t is time
SmacsThis is what I want to have a formular to work out
Eclipsorforgot the other one
P(1+r/t)^nt
purplepenguinsthat is the infinitely compounded rate
TRWBWum, drop the t
Eclipsorthats for none infinitely I think
you sure?
SmacsI have 10,000 which I want to ivest for 12 months, The interest rate is 6.8%, compunded monthly, calculated daily
TRWBWEclipsor: i mean n
Eclipsor:\
TRWBWEclipsor: P*(1+r/n)^n compounds interest r n times
Eclipsorthats the one!
TRWBWEclipsor: limit n->inf P*(1+r/n)^n=p*e^r is infinitely compounded interest
SmacsWhats n?
TRWBWSmacs: how many times you compound.
Smacsper year right?
TRWBWSmacs: 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
SmacsYes 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
SmacsCan anyone confirm I got the correct answer?
mdmkolbe|homeI 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?
actionEclipsor is addicted to graphs
Eclipsoris addicted to graphs
:(
I've been graphing runescape player population since last week :\
and by god, it's >.> interesting
mdmkolbe|homeEclipsor: link?
Eclipsorwww.eclipsor.com/images/rsgraph/w126best.png <-- warning 40000x1000 file
only 300kb though
still need to do some touchups
TRWBWmdmkolbe|home: yes. take for example a set in which no two elements are comparable.
mdmkolbe|home: trivially a poset, but not a lattice
