$$$\frac{1}{\ln\left(c\right)}$$$ 的積分
您的輸入
求$$$\int \frac{1}{\ln\left(c\right)}\, dc$$$。
解答
此積分(對數積分)不存在閉式表示:
$${\color{red}{\int{\frac{1}{\ln{\left(c \right)}} d c}}} = {\color{red}{\operatorname{li}{\left(c \right)}}}$$
因此,
$$\int{\frac{1}{\ln{\left(c \right)}} d c} = \operatorname{li}{\left(c \right)}$$
加上積分常數:
$$\int{\frac{1}{\ln{\left(c \right)}} d c} = \operatorname{li}{\left(c \right)}+C$$
答案
$$$\int \frac{1}{\ln\left(c\right)}\, dc = \operatorname{li}{\left(c \right)} + C$$$A
