I didn't have time to check which was correct, but I reverted your edit because you modified equations without comment. You need to at least use an edit summary to tell us if you think you're doing something useful. At first look, I think that both the old and new ones are wrong, so a talk page discussion might help resolve the problem even better. Dicklyon (talk) 15:22, 15 October 2011 (UTC)
