SIN(3)							   BSD Library Functions Manual 						    SIN(3)

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 lit-
     tle or no significance.

RETURN VALUES

     The sin(), sinf(), and sinl() functions return the sine value.

SEE ALSO

     acos(3), asin(3), atan(3), atan2(3), cos(3), cosh(3), csin(3), math(3), sinh(3), tan(3), tanh(3)

STANDARDS

     These functions conform to ISO/IEC 9899:1999 (``ISO C99'').

NAME

     sin -- sine function

SYNOPSIS

     #include <math.h>

     double
     sin(double x);

     long double
     sinl(long double x);

     float
     sinf(float x);

DESCRIPTION

     The sin() function computes the sine of x (measured in radians).

SPECIAL VALUES

     sin(+-0) returns +-0.

     sin(+-infinity) returns a NaN and raises the "invalid" floating-point exception.

VECTOR OPERATIONS

     If you need to apply the sin() function to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may
     give significantly better performance:

     #include <Accelerate/Accelerate.h>

     vFloat vsinf(vFloat x);
     vFloat vsincosf(vFloat x, vFloat *c);
     void vvsinf(float *y, const float *x, const int *n);
     void vvsin(double *y, const double *x, const int *n);
     void vvsincosf(float *s, float *c, const float *x, const int *n);
     void vvsincos(double *s, double *c, const double *x, const int *n);

SEE ALSO

     acos(3), asin(3), atan(3), atan2(3), cos(3), cosh(3), sinh(3), tan(3), tanh(3), math(3)

STANDARDS

     The sin() function conforms to ISO/IEC 9899:2011.
