Approximation 3 of e

Utilisez la formule approximative pour trouver une approximation de e.

Use the following approximate formula to find an approximation of the base of the natural logarithm e.

e= 1/1! + 2/2! + 3/3! + 4/4! + ･･･

Let's observe how the approximation of the base of the natural logarithm e can be obtained as the number of terms increases.

You can see that the convergence is very fast.
