I am writing an equation using the syntax s follows:-
{
\[
N\!D_{\max} =
\begin{cases}
\frac{n}{2} &: \text{$n$ even,} \\
\frac{n-1}{2} &: \text{$n$ odd.}
\end{cases}
\] }\label{form:19}
I am able to label the equation during a sentence but the same equation number is not being shown beside the equation. How can I fix this problem? A picture
is attached for better understanding.
