单词 ValuesOf11nnFor0N26
释义

values of (1+1/n)n for 0<n<26


The following table gives the numerator and denominator of (1+1n)n as well as the decimal expansion to 20 places.

With a large enough value of n, this formulaMathworldPlanetmathPlanetmath approximates the natural log base e. For example, with n set to ten million, we get 2.7182816925449662712, which is 0.000000135914078964161737245574 short of 2.7182818284590452354 (this calculation took almost four minutes with Mathematica 4.2). It is less computationally intensive to use

i=0n1i!,

which with n set to 100 gives in less than a second a result to 20 places that is indistinguishable from e.
