# MathF.Asinh(Single) Method

## Definition

Returns the angle whose hyperbolic sine is the specified number.

```
public:
static float Asinh(float x);
```

`public static float Asinh (float x);`

`static member Asinh : single -> single`

`Public Shared Function Asinh (x As Single) As Single`

#### Parameters

- x
- Single

A number representing a hyperbolic sine, where `x`

must be greater than or equal to NegativeInfinity, but less than or equal to PositiveInfinity.

#### Returns

An angle, θ, measured in radians, such that -∞ < θ ≤ -1, or 1 ≤ θ < ∞.

## Remarks

Multiply the return value by 180/MathF.PI to convert from radians to degrees.
