For majority of functions the amount of time required for the function to decrease by half depends on the starting point. The symbol for half-life is T½. The ln 2 stands for the natural logarithm of two and can be estimated as 0693 and the l is the decay constant. If an archaeologist found a fossil sample that contained 25 carbon-14 in comparison to a living sample the time of the fossil samples death could be determined by rearranging equation 1 since N t N 0 and t 12 are known.
