该计算器将求$$$\operatorname{acsc}{\left(x \right)}$$$的导数，并显示步骤。

您的输入

求$$$\frac{d}{dx} \left(\operatorname{acsc}{\left(x \right)}\right)$$$。

解答

反余割函数的导数为 $$$\frac{d}{dx} \left(\operatorname{acsc}{\left(x \right)}\right) = - \frac{1}{x^{2} \sqrt{1 - \frac{1}{x^{2}}}}$$$：

$${\color{red}\left(\frac{d}{dx} \left(\operatorname{acsc}{\left(x \right)}\right)\right)} = {\color{red}\left(- \frac{1}{x^{2} \sqrt{1 - \frac{1}{x^{2}}}}\right)}$$

化简：

$$- \frac{1}{x^{2} \sqrt{1 - \frac{1}{x^{2}}}} = - \frac{\left|{x}\right|}{x^{2} \sqrt{x^{2} - 1}}$$

因此，$$$\frac{d}{dx} \left(\operatorname{acsc}{\left(x \right)}\right) = - \frac{\left|{x}\right|}{x^{2} \sqrt{x^{2} - 1}}$$$。

答案

$$$\frac{d}{dx} \left(\operatorname{acsc}{\left(x \right)}\right) = - \frac{\left|{x}\right|}{x^{2} \sqrt{x^{2} - 1}}$$$A
