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

NAME

     sin -- sine function

SYNOPSIS

     #include <math.h>

     double
     sin(double 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.

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 9899:1999(E).

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.
