[其他] 二項式定理與多項式
二項式定理:
在定義0^0=1的前提下,
(x+y)^n
=ΣC(n,k)x^k*y^(n-k){k=0到n}
x,y為複數,n為非負整數。
公式寫得乾淨俐落。
在不定義0^0=1的前提下,
n只能為正整數,
公式要如何寫才正確?
多項式:
對於項次為n+1項之多項式,
c[0]+c[1]*x^1+c[2]*x^2+...+c[n]*x^n
n為非負整數。
在定義0^0=1的前提下,
上式=Σc[k]*x^k{k=0到n}
在不定義0^0=1的前提下,
公式要如何寫才正確?

我已經讓它是正整數了,然後公式怎麼寫?

錯,再思考得縝密一點吧。

看不出哪裡錯。Σa[k]{k=1到0}=a[1]+a[0]
錯在這裡。

討論不定義是否不方便。
當然沒有證明定義對的這回事。
