COS(3)				   BSD Library Functions Manual 			   COS(3)

NAME
     cos, cosf -- cosine function

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     double
     cos(double x);

     float
     cosf(float x);

DESCRIPTION
     The cos() and cosf() functions compute the cosine of x (measured in radians).  A large mag-
     nitude argument may yield a result with little or no significance.  For a discussion of
     error due to roundoff, see math(3).

RETURN VALUES
     The cos() function returns the cosine value.

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

STANDARDS
     The cos() function conforms to ANSI X3.159-1989 (``ANSI C89'').
