Wide equations

The equation that follows is set in a wide format, i.e., it spans across the full page. The wide format is reserved for long equations that cannot be easily broken into four lines or less:

#math98#
#tex2html_wrap_indisplay857#(d) = gσ2e#tex2html_wrap_indisplay858##tex2html_wrap_indisplay859# + #tex2html_wrap_indisplay860##tex2html_wrap_indisplay861# + xWQe#tex2html_wrap_indisplay862##tex2html_wrap_indisplay863# + #tex2html_wrap_indisplay864##tex2html_wrap_indisplay865#  . (8)
This is typed so you can see that the output is in wide format. (Since there is no input line between <#366#>#math99#\end{equation}<#366#> and this paragraph, there is no paragraph indent for this paragraph.) We also have

#math100#
#tex2html_wrap_indisplay872#(f) = - g3δσ1, σ2#tex2html_wrap_indisplay873##tex2html_wrap_indisplay874# - QeDγcosθW#tex2html_wrap_indisplay875##tex2html_wrap_indisplay876##tex2html_wrap_indisplay877#ε1ε2 + #tex2html_wrap_indisplay878#ε1ε3#tex2html_wrap_indisplay879#  . (9)
