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

NAME
     cos, cosf -- cosine functions

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     double
     cos(double	x);

     float
     cosf(float	x);

DESCRIPTION
     The cos() and the cosf() functions	compute	the cosine of x	(measured in
     radians).	A large	magnitude 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() and the cosf() functions	return 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 ISO/IEC 9899:1990 ("ISO C90").
