1) What's the best way to split an long equation surrounded by parenthesis, over several lines ?
What I've been using is unmatched parentheses (i.e. "\left ( + none" at the beginning and "none + \right (" at the end), but this has the disadvantage of not producing "big" parenthesis. Has anyone had this problem before ? 2) Is there a way to set the spacing to one thing for regular body text and another for chapter/section titles other than going one by one :S ? Thanks, Alex
