sin(x), sinh(x) -> odd

cos(x), cosh(x) -> even

tan(x), tanh(x) -> odd

cot(x), coth(x) -> odd

sec(x), sech(x) -> even

csc(x), csch(x) -> odd

arcsin(x), arcsinh(x) -> odd

arccos(x), arccosh(x) ->

**?**

arctan(x), arctanh(x) -> odd

arccot(x), arccoth(x) -> odd

arcsec(x), arcsech(x) ->

**?**

arccsc(x), arccsch(x) -> odd

with base in this comparison above, is correct to attribute a parity for arccos(x), arccosh(x), arcsec(x) and arcsech(x) as being even?
