## SIN(3)

```
```

### NAME[Toc][Back]

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

### LIBRARY[Toc][Back]

```     Math Library (libm, -lm)
```

### SYNOPSIS[Toc][Back]

```     #include <math.h>

double
sin(double x);

float
sinf(float x);
```

### DESCRIPTION[Toc][Back]

```     The sin() and the sinf() functions compute the sine of x (measured in
radians).	A large magnitude argument may yield a result with little or
no significance.
```

### RETURN VALUES[Toc][Back]

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

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

### STANDARDS[Toc][Back]

```     The sin() function conforms to ISO/IEC 9899:1990 (``ISO C89'').

FreeBSD 5.2.1			April 19, 1991			 FreeBSD 5.2.1```
