SINH(3M)            UNIX Programmer's Manual             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
     These functions compute the designated hyperbolic functions
     for real arguments.

DIAGNOSTICS
     _S_i_n_h and _c_o_s_h return a huge value of appropriate sign when
     the correct value would overflow.
