2 Logarithm and Exponential Natural Logarithms: ln x + ln y = ln xy ln x + ln y = ln( x/y) a ln x = ln x a ln x = (ln 10) log x = 2.302585 log x Exponential Functions: e = 2.71828182846… e x e y = e x+y e x / e y = e x-y

15 State function: its value depends only on the current state of the system and is independent of how that state has been prepared. Energy is a state function. What is Energy U? U = P + K K = K order + K random
