NAME
       acosh - return the arc hyperbolic cosine of the parameter


DECLARATION
       genType acosh(genType x);


PARAMETERS
       x
           Specify the value whose arc hyperbolic cosine to return.


DESCRIPTION
       acosh returns the arc hyperbolic cosine of $x$; the non-negative inverse of cosh(). The
       result is undefined if $x < 1$.
