sin, sinf - sine functions
#include <math.h>
double
sin(double x);
float
sinf(float x);
The sin() function computes the sine of x (measured in radians). The
sinf() function is a single 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).
The sin() and sinf() functions return the sine value.

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