■正多面体の正多角形断面(その59)

ここまで計算ミスを重ねてきたが、これ以上はプログラムを組んで、数値計算したい

N=4: .61803

N=5: .57735

N=6: .554958

N=7: .541196

N=8: .532089

N=9: .525731

N=10: .521109

===================================

N=20: .505648

N=30: .502577

N=40: .501466

N=50: .500951

N=60: .500658

N=70: .500483

N=80: .500368

N=90: .500284

N=100: .500202

おそらく予想は正しい。このあたりから数値計算誤差が増大する
