松永良弼の公式２

Features 松永良弼の公式２

Use the following "Yoshisuke Matsunagas formula" to find an approximation of pi.π = 3 ・ {1 + (1 ^ 2) / (4 ・ 6) ＋ (1 ^ 2 ・ 3 ^ 2) / (4 ・ 6 ・ 8 ・ 10) ＋ (1 ^ 2 ・ 3 ^ 2 ・ 5 ^ 2 ) / (4 ・ 6 ・ 8 ・ 10 ・ 12 ・ 14) ＋ ・ ・ ・}Lets observe how the approximate value of pi can be obtained as the number of terms increases.It can be observed that the convergence speed is very fast.
