$$$\sin{\left(x \right)}$$$ 的積分

此計算器將求出 $$$\sin{\left(x \right)}$$$ 的不定積分（原函數），並顯示步驟。

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

正弦函數的積分為 $$$\int{\sin{\left(x \right)} d x} = - \cos{\left(x \right)}$$$：

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

因此，

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

加上積分常數：

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

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