Question

how can I make equations smaller in TeX? For example, I want to use the equation environment as follows:

\begin{equation}
long equation here
\end{equation}

but then it’s displayed in a way that’s too large to fit in the margin. I get around this by using:

$ long equation here $

but then I don’t get the automatic numbering and all the other nice features of equation environments.

secondly, how can I suppress equation numbering for specific equations in \begin{equation}\end{equation}? I’d like equations with no displayed numbers to not count to the total (so if the first 3 equations’ numbers suppressed, but the 4th isn’t, the 4th equation should be labeled “1”).

thanks.

Answer 1

If you like the results you’re getting from $ eqn $, you can get this by putting \textstyle in your equation environment.

To suppress numbering use “*”: \begin{equation*} ... \end{equation*}. You can also use \notag on individual equations in an environment (e.g. align).
