$$$\sin{\left(x_{0} \right)}$$$ 的积分

求$$$\int \sin{\left(x_{0} \right)}\, dx_{0}$$$。

正弦函数的积分为 $$$\int{\sin{\left(x_{0} \right)} d x_{0}} = - \cos{\left(x_{0} \right)}$$$:

$${\color{red}{\int{\sin{\left(x_{0} \right)} d x_{0}}}} = {\color{red}{\left(- \cos{\left(x_{0} \right)}\right)}}$$

因此，

$$\int{\sin{\left(x_{0} \right)} d x_{0}} = - \cos{\left(x_{0} \right)}$$

加上积分常数：

$$\int{\sin{\left(x_{0} \right)} d x_{0}} = - \cos{\left(x_{0} \right)}+C$$

$$$\int \sin{\left(x_{0} \right)}\, dx_{0} = - \cos{\left(x_{0} \right)} + C$$$A
