Graphics, Figures & Tables ⇒ beamer, equation exceeds the bounding box of the environment

[neumannturing]

Hello,
When I use beamer, the theorem environment has a bounding box. But when it contains some long math equations, those equations go outside the bounding box. Because the equations are in math mode, I cannot change the fone size. Any way to fix the problem such that the equations do not go beyond the bounding box?
The screenshot of the problematic slide is in the attachment.
Thank you.

It seems that you are already using the align environment from amsmath. Just split the equation earlier. Provide the code of the equation if necessary.


Best regards and welcome to the board

Thanks for your kindly reply.
I do not want to split the equations in other space. Can I make the font small?
I try to use the \small command, but it does not work.
the code segment is as follows,
\begin{align*}\small
\cA(w_h,v_h)&=\sum_{T\in\cTh}\int_{T}D^2 w_h:D^2 v_hdx\\& +\sum_{e\in\cEh}\int_{e}\m{w_h}\j{v_h}ds+\sum_{e\in\cEh}\int_{e}\m{v_h}\j{w_h}ds\\& +\sum_{e\in\cEh}\dfrac{\sigma}{h_e}\int_{e}\j{w_h}\j{v_h}ds,
\end{align*}

Well, then try to change the font size.

Code: Select all

\small
\begin{align*}
  \cA(w_h,v_h)&=\sum_{T\in\cTh}\int_{T}D^2 w_h:D^2 v_h\,dx \\
  & +\sum_{e\in\cEh}\int_{e}\m{w_h}\j{v_h}ds+\sum_{e\in\cEh}\int_{e}\m{v_h}\j{w_h}\,ds \\
  & +\sum_{e\in\cEh}\dfrac{\sigma}{h_e}\int_{e}\j{w_h}\j{v_h}\,ds
\end{align*}
\normalsize

It works. Thank you.

I do have the same problem with a numerated equation, and it work. However, the number of the equation gets shrink as well.

How could I make the equation smaller without doing smaller the number?

Thank you very much!

You may either want to use iterated \mathsmaller command from the relsize package, e.g., \mathsmaller{\mathsmaller{2+2=4}}, or some kind of scalebox from the graphicx package. Perhaps this question at the TeX SE site might help (that's about making things bigger, but making them smaller is the same basic process).

If you need more help, provide a minimal working example showing your problem.
