Approximation 11 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√2)･{(4･4)/(3･5)}･{(8･8)/(7･9)}･{(12･12)/(11･13)}･{(16･16)/(15･17)}･･･

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