$$$\tanh{\left(u \right)}$$$的导数

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

求$$$\frac{d}{du} \left(\tanh{\left(u \right)}\right)$$$。

双曲正切函数的导数为$$$\frac{d}{du} \left(\tanh{\left(u \right)}\right) = \operatorname{sech}^{2}{\left(u \right)}$$$：

$${\color{red}\left(\frac{d}{du} \left(\tanh{\left(u \right)}\right)\right)} = {\color{red}\left(\operatorname{sech}^{2}{\left(u \right)}\right)}$$

因此，$$$\frac{d}{du} \left(\tanh{\left(u \right)}\right) = \operatorname{sech}^{2}{\left(u \right)}$$$。

$$$\frac{d}{du} \left(\tanh{\left(u \right)}\right) = \operatorname{sech}^{2}{\left(u \right)}$$$A
