$$f(x)=\left{{x^2, \rm~if x>-1\atop~0, \rm~else}\right.$</p><p>(\rm switches to roman style)</p></td><td valign="top" width="33%"><p>f(x)=\left{{x^2, \rm~if x>-1\atop~0, \rm~else}\right.$$

\left.{ ... \right\}

(note the dot!)

$$\left.{{\rm~term1\atop\rm~term2}\right}=y$</td><td valign="top" width="33%">\left.{{\rm~term1\atop \rm~term2}\right}=y$$

Note: The delimiters are automatically sizes.
