"E" is also a natural constant, which is a law of mathematics. It is about 2.7 1828, that is, the formula is lim (1+ 1/x) x, x →∞ or lim (1+z), z→0, which is an infinite non.
As a mathematical constant, e is the basis of natural logarithmic function. Sometimes called Euler number, named after the Swiss mathematician Euler; There is also a rare name, Napier constant, to commemorate the Scottish mathematician John Napier? (John Napier) introduced logarithm. It is one of the most important constants in mathematics, just like pi and imaginary units I and E.

Source of natural constant e:
The first mention of the constant e is a table in the appendix of John Napier's logarithmic works published in 16 18. But it didn't record this constant, only a list of natural logarithms calculated from it, which is generally believed to be made by William Oughtred. It was Jacob Bernoulli who first thought that E was a constant.
The earliest known uses of the constant e are 1690 and 169 1 year, which is represented by B. In 1727, Euler began to use e to represent this constant. E was first used in publications, and it was Euler Mechanics in 1736. Although some researchers later used the letter C, E was widely used and finally became the standard.
