sinh(3M)                                                 sinh(3M)



NAME
     sinh, cosh, tanh - provide 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 hyperbolic
     sine, cosine, and tangent of their argument.

STATUS MESSAGES AND VALUES
     The sinh and cosh programs return HUGE (and sinh may return
     -HUGE 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).
