- log b of mn =
- log b of m + log b of n
- log b of m/n =
- log b of m - log b of n
- inverse of function
- substitute y for x or x for y
- continuously compounded interest
-
a = pe ^ rt
p = starting amount
r = rate
t = time - scientific
- y = ne ^ kt
- appreciation / depreciation
-
V = p(1 +r) ^ n
p = starting amount
r = rate of growth / decay
n = time
