User talk:Quietbritishjim/Sokhotsky's formula

Hi Jim, What does 'v.p.' mean? I can't find the abbreviation anywhere, not on Wikipedia (most notably not on List of mathematical abbreviations), and not on Google. Perhaps you should add it to this draft article, and/or to the list of abbreviations? Cheers, --Sietse (talk) 16:41, 13 April 2012 (UTC)
