Usa la formula approssimativa per trovare l'approssimazione di e.
Use the following approximate formula to find the approximation of the base of the natural logarithm e.
e = 1 + 1/1! + 1/2! + 1/3! + 1/4! + ･･･
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.
