NAME

6       sin, sinf, sinl - sine function
7

SYNOPSIS

9       #include <math.h>
10
11       double sin(double x);
12       float sinf(float x);
13       long double sinl(long double x);

15       Link with -lm.

17   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
18
19       sinf(), sinl(): _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 ||
20       _ISOC99_SOURCE; or cc -std=c99
21

DESCRIPTION

23       The sin() function returns the sine of x, where x is given in radians.
24

RETURN VALUE

26       On success, these functions return the sine of x.
27
28       If x is a NaN, a NaN is returned.
29
30       If x is positive infinity or negative infinity, a domain error  occurs,
31       and a NaN is returned.
32

ERRORS

34       See  math_error(7) for information on how to determine whether an error
35       has occurred when calling these functions.
36
37       The following errors can occur:
38
39       Domain error: x is an infinity
40              An invalid floating-point exception (FE_INVALID) is raised.
41
42       These functions do not set errno.
43

CONFORMING TO

45       C99, POSIX.1-2001.  The variant returning double also conforms to SVr4,
46       4.3BSD, C89.
