sin, sinf, sinl - sine function
double sin(double x); float sinf(float x); long double sinl(long double x);
Link with -lm.

These functions return the sine of x, where x is given in radians.
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.
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
- errno is set to EDOM (but see BUGS). An invalid floating-point exception (FE_INVALID) is raised.
For an explanation of the terms used in this section, see attributes(7).

C99, POSIX.1-2001, POSIX.1-2008.
The variant returning double also conforms to SVr4, 4.3BSD, C89.
Before version 2.10, the glibc implementation did not set errno to EDOM when a domain error occurred.
