SINH(3M)        DOMAIN/IX Reference Manual (SYS5)        SINH(3M)



NAME
     sinh, cosh, tanh - hyperbolic functions

USAGE
     #include <math.h>

     double sinh (x)
     double x;

     double cosh (x)
     double x;

     double tanh (x)
     double x;

DESCRIPTION
     Sinh, cosh, and tanh return, respectively, the hyberbolic
     sine, cosine, and tangent of their arguments.

DIAGNOSTICS
     Sinh and cosh return HUGE (and sinh may return -HUGE for
     negative x) when the correct value would overflow.  The
     functions all set errno to ERANGE when this occurs.
