先不管第二階段的好了
我把第一階段的九片求了面積
令半徑為 1 如果我式子沒列錯的話
(因為算是 Mathematica 在幫我算...)
※ 引述《puzzlez (帕索)》之銘言：
: 單位長度：圓周的 1/12
: 編號1： 1 2 ( 2
0.238201
: 編號2： 1.5 ( 1.25 ( 2.5
0.369566
: 編號3： 1 1.5 ( 2
0.234328
: 編號4： 1 ( 1.5 ( 2
0.31262
: 編號5： ( 1.5 ( 2 1.25
0.352882
: 編號6： 2 2 ( 3
0.604226
: 編號7： ( 1 ( 2 ( 1.5
0.336219
: 編號9： ( 1 ( 2 1.5
0.257927
: 編號10： 3 ( 3 ( 1.5
0.560151
然後把它們全部加起來得到...3.26612 竟然和理論值 π 差到了 4% !
所以帕索你確定這些數字是對的嗎?

有人喜歡邊玩遊戲邊上逼；
也有人喜歡邊聽歌邊打字。
但是，我有個請求，
選字的時候請專心好嗎？
