[其他] Generating function
一題課本習題,老師說課本的答案他覺得是錯的,但他自己也不確定
所以來這裡發問
Find a generating function for an , the number of partitions of n into
three parts in which no part is larger than the sum of the other two.
(其實就是問分成三角形的三個邊)
課本答案: (x^3 + x^6) / (1-x^3)(1-x^4)(1-x^6)
老師的答案: x^3 / (1-x^2)(1-x^3)(1-x^4)
因為老師說他不是100%確定答案,所以想問這裡的各位,
有沒有人可以算出哪個答案是正確的或是有其他答案
感恩!!
