## COS(3)

```

### NAME[Toc][Back]

```     sin, sinf - sine functions
```

### SYNOPSIS[Toc][Back]

```     #include <math.h>

double
sin(double x);

float
sinf(float x);
```

### DESCRIPTION[Toc][Back]

```     The sin() function computes the sine of x (measured in radians).  The
sinf()  function  is a single precision version of sin().  A
large magnitude
argument may yield a result with little or no  significance.  For a
discussion of error due to roundoff, see math(3).
```

### RETURN VALUES[Toc][Back]

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

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

### STANDARDS[Toc][Back]

```     The sin() function  conforms  to  ANSI  X3.159-1989  (``ANSI
C'').

OpenBSD      3.6                            May      2,      1991
