I have a rather long document with plenty of equations. As the equations are quite long I have chosen to use 8pt for equations in the display mode instead of the 10pt normal size.
\DeclareMathSizes{10}{8}{6}{6} globally changes all equations in math mode to 8pt font – Thats what I have done so far. Is there a way to stick with 10pt in textstyle equations?, i.e. is it possible to differentiate between displaystyle and textstyle?
