## SINH(3)

```
```

### NAME[Toc][Back]

```     sinh, sinhf - hyperbolic sine functions
```

### SYNOPSIS[Toc][Back]

```     #include <math.h>

double
sinh(double x);

float
sinhf(float x);
```

### DESCRIPTION[Toc][Back]

```     The sinh() function computes the hyperbolic sine of x.   The
sinhf() function
is a single precision version of sinh().
```

### RETURN VALUES[Toc][Back]

```     The  sinh() and sinhf() functions return the hyperbolic sine
value unless
the magnitude of x is too large; in this event,  the  global
variable errno
is set to ERANGE.
```

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

### STANDARDS[Toc][Back]

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