#ed_op#DIV#ed_cl#是的#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#Fibonacci sequence 的定義即為#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#F0=0 F1=1 F(n+2)=F(n+1)+F(n)#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#所以為 0,1,1,2,3,5,8,13,21,34,55,89...#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl# #ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#而一般通式大概就是大家知道的#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#Fn=1/√5[(1+√5 /2)^n - (1-√5 /2)^n]#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#我覺得這就很漂亮了啊 ^^#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl# #ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#如果你利用 golden ratio 代入的話是可以得到比較"好看"一點的式子 #ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#不過基本上視情況來看要用哪種式子會比較好#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl# #ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#Fabonacci sequence 在大學Number Theory裡都只有一小篇章,資料有限#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl# #ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#不過MathWorld有不少資料,可以查查看,相信對你會有幫助的#ed_op#/DIV#ed_cl#
