Disputatio:Circulus

I have chosen the terms "passans", "tangens" and "secans" following the terms passant, tangent and secant. However, I could not find a verb "passare" in my Latin dictionary and besides, I think there might be some problems with the names of the trigonometric functions tangent and secant. Does anybody have an idea whether and, if yes, how I shall rename the different straight lines? Thanks in advance! --Ahib 17:18, 17 Aprilis 2008 (UTC)
