Changes to spacing

Sometimes LATEX needs a little help in spacing an expression, or perhaps you think that the default spacing needs adjusting. For these purposes we have the following spacing commands:


\, thin space   \: medium space
\! negative thin space   \; thick space
\quad a quad of space   \qquad two quads of space


The spacing commands \,, \quad, and \qquad can be used in paragraphing mode, too. Here are some examples of these spacing commands used to make subtle modifications to some expressions.

\begin{mathegs}
\verb@$\sqrt{2} \, x$@ & $\sqrt{2} \, x$\\
\verb@$\int_a^b f(x)...
... & $x / \! \sin x$\\
\verb@$\sqrt{\,\sin x}$@ & $\sqrt{\,\sin x}$
\end{mathegs}
