2020年9月7日 · python中二维数组初始化的问题 [[0]*n]*n和[[0]*n for i in range(n)]的区别 正确初始化： s = [[0] * n for i in range(n)] 或者： [[0 for j in range(n)] for i in range(n)] 以上两个皆可。

The series $$ e^x=\sum_{n=0}^\infty\frac{x^n}{n!} $$ converges for all $x\in\mathbb R$. Hence, $$ \frac{x^n}{n!}\to0 $$ for all $x\in\mathbb R$.

再提一种比较罗嗦的方法，我们可以证明 \sum_{n=1}^{\infty}{\frac{x^n}{n!}} 收敛，然后根据收敛级数的项必然趋近于0。 若 \sum_{n=1}^{\infty}{a_n} 收斂，則 \lim_{n \rightarrow \infty}{a_n} =0 項測試
