$$$\sin{\left(a \right)}$$$ 关于$$$x$$$的积分

该计算器将求出$$$\sin{\left(a \right)}$$$关于$$$x$$$的积分/原函数，并显示步骤。

求$$$\int \sin{\left(a \right)}\, dx$$$。

应用常数法则 $$$\int c\, dx = c x$$$，使用 $$$c=\sin{\left(a \right)}$$$：

$${\color{red}{\int{\sin{\left(a \right)} d x}}} = {\color{red}{x \sin{\left(a \right)}}}$$

因此，

$$\int{\sin{\left(a \right)} d x} = x \sin{\left(a \right)}$$

加上积分常数：

$$\int{\sin{\left(a \right)} d x} = x \sin{\left(a \right)}+C$$

$$$\int \sin{\left(a \right)}\, dx = x \sin{\left(a \right)} + C$$$A
