$$$2 \sinh{\left(v \right)}$$$的导数
您的输入
求$$$\frac{d}{dv} \left(2 \sinh{\left(v \right)}\right)$$$。
解答
对 $$$c = 2$$$ 和 $$$f{\left(v \right)} = \sinh{\left(v \right)}$$$ 应用常数倍法则 $$$\frac{d}{dv} \left(c f{\left(v \right)}\right) = c \frac{d}{dv} \left(f{\left(v \right)}\right)$$$：
$${\color{red}\left(\frac{d}{dv} \left(2 \sinh{\left(v \right)}\right)\right)} = {\color{red}\left(2 \frac{d}{dv} \left(\sinh{\left(v \right)}\right)\right)}$$双曲正弦函数的导数为 $$$\frac{d}{dv} \left(\sinh{\left(v \right)}\right) = \cosh{\left(v \right)}$$$：
$$2 {\color{red}\left(\frac{d}{dv} \left(\sinh{\left(v \right)}\right)\right)} = 2 {\color{red}\left(\cosh{\left(v \right)}\right)}$$因此，$$$\frac{d}{dv} \left(2 \sinh{\left(v \right)}\right) = 2 \cosh{\left(v \right)}$$$。
答案
$$$\frac{d}{dv} \left(2 \sinh{\left(v \right)}\right) = 2 \cosh{\left(v \right)}$$$A
