Hello, had a quick search but couldn't find any other threads about this.
I'm using the align environment to typeset a series of equations. They are fairly large equations with lots of fractions and as such are looking rather squashed together with the standard spacing. I was wondering if there's a way of stretching the vertical spacing within this environment? I did have a play at using \smallskip etc, but it doesn't seem to make any difference - I'm not sure if I'm just putting it in the wrong part of the line though.
