NAME
sin, sinf, sinl – sine functions
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
sin(double x);
float
sinf(float x);
long double
sinl(long double x);
DESCRIPTION
The sin(), sinf(), and sinl() functions compute the sine of x (measured in radians). A large magnitude argument may yield a result with little or no significance.
RETURN VALUES
The sin(), sinf(), and sinl() functions return the sine value.
