This study suggests that Euler's formula including time as a variable [exp(it) =cos(t) + isin(t)] gives, through a series of 7T/2 rotations of axes of tirne [imaginary time (it) and real time (t)], exponential functions with base e [exp(t) and exp(-t)] used for the growih analysis of ruminants and forages.
