SIN(3) Linux Programmer's Manual SIN(3)NAME
sin, sinf, sinl - sine function
SYNOPSIS
#include <math.h>
double sin(double x);
float sinf(float x);
long double sinl(long double x);
Link with -lm.
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
sinf(), sinl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 ||
_ISOC99_SOURCE; or cc -std=c99
DESCRIPTION
The sin() function returns the sine of x, where x is given in radians.
RETURN VALUE
On success, these functions return the sine of x.
If x is a NaN, a NaN is returned.
If x is positive infinity or negative infinity, a domain error occurs,
and a NaN is returned.
ERRORS
See math_error(7) for information on how to determine whether an error
has occurred when calling these functions.
The following errors can occur:
Domain error: x is an infinity
An invalid floating-point exception (FE_INVALID) is raised.
These functions do not set errno.
CONFORMING TO
C99, POSIX.1-2001. The variant returning double also conforms to SVr4,
4.3BSD, C89.
