COSH(3)                    Library Functions Manual                    COSH(3)

NAME
     cosh, coshf, coshl, - hyperbolic cosine function

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     double
     cosh(double x);

     float
     coshf(float x);

     long double
     coshl(long double x);

DESCRIPTION
     The cosh(), coshf() and coshl() functions compute the hyperbolic cosine
     of x.

RETURN VALUES
     If the magnitude of x is too large, cosh(x) and coshf(x) return Inf and
     sets the global variable errno to ERANGE.

     tan(3), tanh(3)

STANDARDS
     The cosh() function conforms to ANSI X3.159-1989 ("ANSI C89").
