compound interest, exponential growth/decay, basic properties of logs

compound interest formula

A= P(1+r/n)^nt

continuous compound interest

A=Pe^rt

exponential growth formula

y=a(1+r)^t

exponential decay forumla

y=a(1-r)^t

continuous exponential growth

N=N₀e^kt

continuous exponential decay

N=N₀e^-kt

logarithmic form

logb (x)= E

exponential form

b^E=x

(bc its the same rules and its easier to type) log1

0

log10

1

log10^x

x

10^logx

x
