## C# Math.Asinh() – Examples

In this tutorial, we will learn about the C# Math.Asinh() method, and learn how to use this method to find the angle whose hyperbolic sine is the specified number, with the help of examples.

## Asinh(Double)

Math.Asinh(d) returns the angle whose hyperbolic sine is the specified number `d`.

### Syntax

The syntax of Asinh(d) method is

`Math.Asinh(Double d)`

where

Return Value

The method returns a Double value.

### Example 1 – Asinh(Double)

In this example, we will give different values ranging from Negative Infinity to Positive Infinity to Asinh() method, and find the corresponding angles, in radians.

C# Program

```using System;

class Example {
static void Main(string[] args) {
Double d, result;

d = Double.NegativeInfinity;
result = Math.Asinh(d);
Console.WriteLine(\$"Asinh({d}) = {result} radians.");

d = -5;
result = Math.Asinh(d);
Console.WriteLine(\$"Asinh({d}) = {result} radians.");

d = -1;
result = Math.Asinh(d);
Console.WriteLine(\$"Asinh({d}) = {result} radians.");

d = 0;
result = Math.Asinh(d);
Console.WriteLine(\$"Asinh({d}) = {result} radians.");

d = 1;
result = Math.Asinh(d);
Console.WriteLine(\$"Asinh({d}) = {result} radians.");

d = 5;
result = Math.Asinh(d);
Console.WriteLine(\$"Asinh({d}) = {result} radians.");

d = Double.PositiveInfinity;
result = Math.Asinh(d);
Console.WriteLine(\$"Asinh({d}) = {result} radians.");
}
}```

Output

```Asinh(-∞) = -∞ radians.
Asinh(-5) = -2.31243834127275 radians.
Asinh(-1) = -0.881373587019543 radians.
Asinh(0) = 0 radians.
Asinh(1) = 0.881373587019543 radians.
Asinh(5) = 2.31243834127275 radians.
Asinh(∞) = ∞ radians.```

### Conclusion

In this C# Tutorial, we have learnt the syntax of C# Math.Asinh() method, and also learnt how to use this method with the help of C# example programs.
