[Tex/LaTex] Specify font and font size for equations and math mode?

equationsfontsizemath-mode

I am using a class file that defines commands to change the font and font sizes for normal text for different sections of the document, but it leaves the math mode and equation font and font sizes unchanged. Consequently, in one of the sections, all the math is huge compared to the text (and in the wrong font). How do I change the font and font size for all the math in a particular section?

I just found something over at Stack Overflow that works for me:

\begingroup
\fontsize{7pt}{9pt}\selectfont
<whatever>
