Sometimes the following symbols are used instead of an equal sign. I think the single one ~ means "is proportional to". One of the other ones means "is approximately". Which one is it? I'm guessing the second one because LaTex calls it approx. When are the others used?
[tex]
\begin{array}{l}
\sim \\
\approx \\
\simeq \\
\cong \\
\end{array}
[/tex]
