昨天,<<絕代商驕>>的黃子華說道:「所謂一本萬利,零成本姐係無限利潤啦」
呢句我並不同意。
首先,一除以零不等於無限,是沒有定義的。
而且成本非常接近零(而不等於零)呢樣野係冇可能的
Proof:
Assume that there is a set with finite elements such that 1 < E < 0
There exists a smallest element E_0,
but E_0 /2 is also in the set.
Contradiction!
Therefore, between 0 and 1, there are infinite numbers.
=> In set with infinite elements, there does not exist a smallest element.
第二:
一本=>萬利 假設中間是由f(x) 作聯繫,
只有f(1) = 10000
是不能imply f(0) = infinity 的
而且「一本萬利」這4字沒有透露之間的關係何在
所以我不同意他的說法。
