Your Input

Find $$$\frac{d}{du} \left(\frac{u}{2}\right)$$$.

Solution

Apply the constant multiple rule $$$\frac{d}{du} \left(c f{\left(u \right)}\right) = c \frac{d}{du} \left(f{\left(u \right)}\right)$$$ with $$$c = \frac{1}{2}$$$ and $$$f{\left(u \right)} = u$$$:

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

Apply the power rule $$$\frac{d}{du} \left(u^{n}\right) = n u^{n - 1}$$$ with $$$n = 1$$$, in other words, $$$\frac{d}{du} \left(u\right) = 1$$$:

$$\frac{{\color{red}\left(\frac{d}{du} \left(u\right)\right)}}{2} = \frac{{\color{red}\left(1\right)}}{2}$$

Thus, $$$\frac{d}{du} \left(\frac{u}{2}\right) = \frac{1}{2}$$$.

Answer

$$$\frac{d}{du} \left(\frac{u}{2}\right) = \frac{1}{2}$$$A
