How would you write the region D given by

[tex]
\[D: \left\{
\begin{array}{l l}
\frac{-d}{2} \leq y \leq \frac{d}{2} \\
-\infty < x < \infty \\ \end{array} \right. \]
[/tex]

in polar coordinates?

Or, more specifically, how to write x and y in polar coordinates. Replace x and y in the inequalities with those and solve the inequalities.
