Don't confuse module names with file names. There
is a Math module, of course, it's just part of the
core and there's no corresponding require.

Whether these things belong in Math is a question 
I can't answer. I assume they'd only get stuck in
Math if you loaded the library. And anyway, some
of these are probably already there. Isn't there
a Math.sinh in 1.7.x?
