Your Input

Find $$$\frac{d}{dx} \left(x + \frac{1}{2}\right)$$$.

Solution

The derivative of a sum/difference is the sum/difference of derivatives:

$${\color{red}\left(\frac{d}{dx} \left(x + \frac{1}{2}\right)\right)} = {\color{red}\left(\frac{d}{dx} \left(x\right) + \frac{d}{dx} \left(\frac{1}{2}\right)\right)}$$

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

$${\color{red}\left(\frac{d}{dx} \left(\frac{1}{2}\right)\right)} + \frac{d}{dx} \left(x\right) = {\color{red}\left(0\right)} + \frac{d}{dx} \left(x\right)$$

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

$${\color{red}\left(\frac{d}{dx} \left(x\right)\right)} = {\color{red}\left(1\right)}$$

Thus, $$$\frac{d}{dx} \left(x + \frac{1}{2}\right) = 1$$$.

Answer

$$$\frac{d}{dx} \left(x + \frac{1}{2}\right) = 1$$$A
