Calculates sines and hyperbolic sines.

## Syntax

```double sin(
double x
);
float sin(
float x
);  // C++ only
long double sin(
long double x
);  // C++ only
float sinf(
float x
);
long double sinl(   long double x
);
double sinh(
double x
);
float sinh(
float x
);  // C++ only
long double sinh(
long double x
);  // C++ only
float sinhf(
float x
);
long double sinhl(
long double x
);

```

`x`

## Return Value

The `sin` functions return the sine of `x`. If `x` is greater than or equal to 263, or less than or equal to –263, a loss of significance in the result occurs.

The `sinh` functions return the hyperbolic sine of `x`. By default, if the result is too large, `sinh` sets `errno` to `ERANGE` and returns ±`HUGE_VAL`.

## Remarks

Because C++ allows overloading, you can call overloads of `sin` and `sinh` that take and return `float` or `long double` values. In a C program, `sin` and `sinh` always take and return `double`.

## Requirements

`sin`, `sinf`, `sinl`, `sinh`, `sinhf`, `sinhl`<math.h>

## Example

```// crt_sincos.c
// This program displays the sine, hyperbolic
// sine, cosine, and hyperbolic cosine of pi / 2.
//

#include <math.h>
#include <stdio.h>

int main( void )
{
double pi = 3.1415926535;
double x, y;

x = pi / 2;
y = sin( x );
printf( "sin( %f ) = %f\n", x, y );
y = sinh( x );
printf( "sinh( %f ) = %f\n",x, y );
y = cos( x );
printf( "cos( %f ) = %f\n", x, y );
y = cosh( x );
printf( "cosh( %f ) = %f\n",x, y );
}

```
```sin( 1.570796 ) = 1.000000
sinh( 1.570796 ) = 2.301299
cos( 1.570796 ) = 0.000000
cosh( 1.570796 ) = 2.509178
