The easy way: use the fontspec package, it takes care of this for you.

The harder way: in case you defined your text fonts yourself, with  
stuff like:

\DeclareFontFamily{U}{optima}{}
\DeclareFontShape{U}{optima}{m}{n}
   {<-> "Optima\space Regular:mapping=tex-text"}{}
\DeclareFontShape{U}{optima}{m}{it}
   {<-> "Optima\space Italic:mapping=tex-text"}{}
\DeclareFontShape{U}{optima}{b}{n}
   {<-> "Optima\space Bold:mapping=tex-text"}{}
\DeclareFontShape{U}{optima}{b}{it}
   {<-> "Optima\space Bold\space Italic:mapping=tex-text"}{}
\DeclareFontShape{U}{optima}{m}{sl}
   {<-> ssub * optima/m/it}{}
\DeclareFontShape{U}{optima}{b}{sl}
   {<-> ssub * optima/b/it}{}
\DeclareFontShape{U}{optima}{bx}{n}
   {<-> ssub * optima/b/n}{}
\DeclareFontShape{U}{optima}{bx}{it}
   {<-> ssub * optima/b/it}{}
\DeclareFontShape{U}{optima}{bx}{sl}
   {<-> ssub * optima/b/it}{}
\renewcommand{\sfdefault}{optima}
\renewcommand{\familydefault}{\sfdefault}
\renewcommand{\encodingdefault}{U}

then all you have to do is add:

\SetSymbolFont{operators}{normal}{\encodingdefault}{\familydefault}{m} 
{n}
\SetSymbolFont{operators}{bold}  {\encodingdefault}{\familydefault}{b} 
{n}
\SetMathAlphabet{\mathrm}{normal}{\encodingdefault}{\familydefault}{m} 
{n}
\SetMathAlphabet{\mathbf}{normal}{\encodingdefault}{\familydefault}{b} 
{n}
\SetMathAlphabet{\mathit}{normal}{\encodingdefault}{\familydefault}{m} 
{it}
\SetMathAlphabet{\mathrm}{bold}  {\encodingdefault}{\familydefault}{b} 
{n}
\SetMathAlphabet{\mathit}{bold}  {\encodingdefault}{\familydefault}{b} 
{it}

Beware: it's not fullproof at all, and may create problems with math  
accents, in particular. fontspec takes steps to make sure this does  
not happen.
