The \boldmath
macro does this. It is provided by the LaTeX core and switches to bold math for all following math material. There is an \unboldmath
to switch it off again. These macros must be used outside the math code.
\documentclass{article}
\begin{document}
\boldmath
$x=2$
\[ x=2 \]
\end{document}
the equation
environment is meant for a "single" equation, which may be either one line or a "subsidiary" multi=line group such as aligned
. it will not break, even with an explicit \displaybreak
.
furthermore, nesting align
within equation
will produce an error message:
! Package amsmath Error: Erroneous nesting of equation structures;
(amsmath) trying to recover with `aligned'.
trying to use \displaybreak
in this situation will produce another error:
! Package amsmath Error: \displaybreak cannot be applied here.
error messages should be heeded.
if you remove the equation
environment and simply use align
, in the presence of the global \allowdisplaybreaks
command, the multi-line display will break at the end of a page at the normal page length. even without \allowdisplaybreaks
, an explicit \displaybreak
will force a break after the line on which the command appears.
if no numbers are wanted on any line, the environment align*
can be used. and if only a single tag is wanted for the group, with align*
it is possible to insert a manual label using the \tag{...}
command on the desired line. the value will have to be handled manually. to do that, just before the display, issue the command
\stepcounter{equation}
and for the explicit label, use \tag{\theequation}
.
Best Answer
Two thoughts come to mind.
Put a
\scalebox
command from thegraphicx
packagewill make an equation twice as big as normal.
\displaystyle
forces the same display needed under\[
...\]
, since$
...$
would normally use\textstyle
(cause operators to act differently).Another option would be to use the
\mathlarger
and\mathsmaller
commands from therelsize
package.I'm sure there are other options too.
