Some calculations about the number of Jiugong
Nine-Palace Rotation 1,8,3,4,9,2,7,6, calculate the sequence formula for this periodic sequence, the result is very complicated: 1/8 cos(1/4 π (n – 8)) + 1/8 cos(1/2 π (n – 8)) + 1/8 cos(3/4 π (n – 8)) + 1/8 cos(π (n – 8)) + 1/8 cos(5/4 π (n – 8)) + 1/8 cos(3/2 π (n – … 阅读全文 Some calculations about the number of Jiugong
