NAME
sqrt -- square root function

SYNOPSIS
#include <math.h>

double
sqrt(double x);

long double
sqrtl(long double x);

float
sqrtf(float x);

DESCRIPTION
The sqrt() function compute the non-negative square root of x.

SPECIAL VALUES
sqrt(-0) returns -0.

sqrt(x) returns a NaN and generates a domain error for x < 0.

VECTOR OPERATIONS
If you need to apply the sqrt() 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 vsqrtf(vFloat x);
vFloat vrsqrtf(vFloat x);
void vvsqrtf(float *y, const float *x, const int *n);
void vvsqrt(double *y, const double *x, const int *n);
void vvrsqrtf(float *y, const float *x, const int *n);
void vvrsqrt(double *y, const double *x, const int *n);

math(3)

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

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);
