====== Writing Charge Densities ======

===== The Prompt =====

** "Write the charge density that is defined by":**


$$
\rho =
\begin{cases}
0, & \text{if z > L} \\
12, & \text{if  -L < z < L}\\
0, & \text{if z < -L}
\end{cases}
$$

===== Context =====

This [[strategy:smallwhiteboard:|SWBQ]] opens up conversation on how to mathematically represent a charge density defined by a piecewise function.
