Approximation 13 of Pi

Utilisez la formule approximative pour trouver l'approximation de pi.

Use the following approximate formula to find the approximation of pi.

π = (2√3)･{1 - (1/3)･(1/3^1) + (1/5)･(1/3^2) - (1/7)･(1/3^3) + (1/9)･(1/3^4) - ･･･}

Let's observe how the approximate value of pi can be obtained as the number of terms increases.

You can see that the convergence is very fast.
