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.
