General ⇒ vertical spacing in math

[spiegboy]

i write multiline equations in the environment of 'gather', but i dont know how to create vertical space between the equations
i use \smallskip, it doesnt work.

Hi,

an option (if I understood your question correctly):

Code: Select all

\documentclass{report}
\usepackage{amsmath}

\begin{document}

text text text text...
\begin{gather}
  A=b\\
  C=d\\
  D=e\\[4em]
  F=g\\[2em]
  H=i
\end{gather}
text text text text...

\end{document}

[spiegboy]

it works very well, but still one problem

the equations in the gather environment wont break the pape automatically, so making extra blank space between the graphs.
i wonder if the gather environment could be redefined or costomized to make the equations break the page automatically.

thank you very much

Search the documentation of amsmath for \allowdisplaybreaks and \displaybreak.

Hi,

if you don't want to adjust the spacing for every line but use the same vertical space after each line you could change the length \jot, try:

Code: Select all

\documentclass[a4paper,10pt]{article}
\usepackage{amsmath}
\setlength{\jot}{20pt}
\begin{document}
\begin{gather}
 x = 1 \\
 y = 2
\end{gather}
\end{document}

Of couse you can change \jot also just locally.

got it, put \allowdisplaybreaks[2] in the preamble, it works fine
thanks a lot
