Find $$$\frac{d}{dz} \left(\cos{\left(x y \right)}\right)$$$.


The derivative of a constant is $$$0$$$:

$${\color{red}\left(\frac{d}{dz} \left(\cos{\left(x y \right)}\right)\right)} = {\color{red}\left(0\right)}$$

Thus, $$$\frac{d}{dz} \left(\cos{\left(x y \right)}\right) = 0$$$.


$$$\frac{d}{dz} \left(\cos{\left(x y \right)}\right) = 0$$$A
