SINH(3M)             INTERACTIVE UNIX System             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
               The sinh, cosh, and tanh functions return, respectively, the
               hyberbolic sine, cosine and tangent of their argument.

          SEE ALSO
               matherr(3M).

          DIAGNOSTICS
               The sinh and cosh functions 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).
