COSH(3) 	      DragonFly Library Functions Manual	       COSH(3)

NAME
     cosh, coshf -- hyperbolic cosine functions

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     double
     cosh(double x);

     float
     coshf(float x);

DESCRIPTION
     The cosh() and the coshf() 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.

SEE ALSO
     acos(3), asin(3), atan(3), atan2(3), ccosh(3), cos(3), math(3), sin(3),
     sinh(3), tan(3), tanh(3)

STANDARDS
     The cosh() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
