Your Input

Find $$$\frac{d}{dy} \left(\pi n y\right)$$$.

Solution

Apply the constant multiple rule $$$\frac{d}{dy} \left(c f{\left(y \right)}\right) = c \frac{d}{dy} \left(f{\left(y \right)}\right)$$$ with $$$c = \pi n$$$ and $$$f{\left(y \right)} = y$$$:

$${\color{red}\left(\frac{d}{dy} \left(\pi n y\right)\right)} = {\color{red}\left(\pi n \frac{d}{dy} \left(y\right)\right)}$$

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

$$\pi n {\color{red}\left(\frac{d}{dy} \left(y\right)\right)} = \pi n {\color{red}\left(1\right)}$$

Thus, $$$\frac{d}{dy} \left(\pi n y\right) = \pi n$$$.

Answer

$$$\frac{d}{dy} \left(\pi n y\right) = \pi n$$$A
