Usa la formula approssimativa per trovare un'approssimazione di 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.
