Category talk:Trigonometry

What goes here? What goes in Category:Trigonometric Functions? In general, I tend to find it easy to figure out whether a proof belongs in a category relating to a certain object, but not so much whether it belongs in a category relating to a field of mathematics. --Dfeuer (talk) 09:17, 17 January 2013 (UTC)

Well leave it anyway, because a) there are plenty of pages which link to this category and b) not everyone has your difficulty. --prime mover (talk) 09:19, 17 January 2013 (UTC)

I wasn't going to do anything to it at all. I'm just trying to figure out what the convention is here. --Dfeuer (talk) 09:20, 17 January 2013 (UTC)

It evolved. --prime mover (talk) 09:32, 17 January 2013 (UTC)
