SINH(3M)                             SysV                             SINH(3M)



NAME
     sinh, cosh, tanh - hyperbolic functions

SYNOPSIS
     #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 argument.

SEE ALSO
     matherr(3M).

DIAGNOSTICS
     sinh and cosh return HUGE_VAL (and sinh may return -HUGE_VAL for negative
     x) when the correct value would overflow and set errno to ERANGE.

     These error-handling procedures may be changed with the function
     matherr(3M).
