Name           Description 
cosh()         Hyperbolic cosine (exp(arg) + exp(-arg))/2 
sinh()         Hyperbolic sine (exp(arg) - exp(-arg))/2 
tanh()         Hyperbolic tangent sinh(arg)/cosh(arg) 
acosh()        Inverse hyperbolic cosine 
asinh()        Inverse hyperbolic sine 
atanh()        Inverse hyperbolic tangent
