COS(3) OpenBSD Programmer's Manual COS(3)NAME
sin, sinf, sinl - sine functions
SYNOPSIS
#include <math.h>
double
sin(double x);
float
sinf(float x);
long double
sinl(long double x);
DESCRIPTION
The sin() function computes the sine of x (measured in radians). The
sinf() function is a single precision version of sin(). The sinl()
function is an extended precision version of sin(). 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 sin(), sinf() and sinl() functions return the sine value.

tanh(3)STANDARDS
The sin() function conforms to ANSI X3.159-1989 (``ANSI C'').
