SIN(3) BSD Library Functions Manual SIN(3)NAME
sin, sinf -- sine function
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
sin(double x);
float
sinf(float x);
DESCRIPTION
The sin() function computes the sine of x (measured in radians). A large magnitude argument may yield a result with little or no signifi-
cance.
RETURN VALUES
The sin() function returns the sine value.
SEE ALSO acos(3), asin(3), atan(3), atan2(3), cos(3), cosh(3), math(3), sinh(3), tan(3), tanh(3)STANDARDS
The sin() function conforms to ANSI X3.159-1989 (``ANSI C89'').

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