Sorted by: 4 In this case it means "identically equal" and is a shortcut for saying that a function is defined or that some identity holds for all function values, in contrast to $f (x)=x$ which could also mean a fixed-point equation (that is, $f$ is given and one looks for specific $x$ ). use \begin{equation}\end{equation}. the eqnarray* environment instead.
