Talk:hyperbolic tangent

Is hyperbolic tangent countable?
The entry indicates that hyperbolic tangent is countable, and cosine has a page for its plural (cosines), but this sounds like one particular function in mathematics (which would be uncountable). I've created hyperbolic tangents (sorry if I was out of turn there), and I just wanted to check before I create hyperbolic sines and hyperbolic cosines. — TeragR disc./con. 20:11, 30 October 2014 (UTC)
