■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
