# C# Math - Sinh() Method

The C# Sinh() method returns hyperbolic sine of a value. The hyperbolic sine of x is defined as:

where e is an Euler's number.

In special cases it returns the following:

• If the argument is NaN, the method returns NaN.
• If the argument is positive infinity or negative infinity, the method returns a Double equal to argument.

### Syntax

```public static double Sinh(double arg);
```

### Parameters

 `arg` Specify the value.

### Return Value

Returns the hyperbolic sine of a value.

### Example:

In the example below, Sinh() method is used to find out the hyperbolic sine of a value.

```using System;

class MyProgram {
static void Main(string[] args) {
Console.WriteLine("Math.Sinh(-2) = "
+ Math.Sinh(-2));
Console.WriteLine("Math.Sinh(-1) = "
+ Math.Sinh(-1));
Console.WriteLine("Math.Sinh(0) = "
+ Math.Sinh(0));
Console.WriteLine("Math.Sinh(1) = "
+ Math.Sinh(1));
Console.WriteLine("Math.Sinh(2) = "
+ Math.Sinh(2));
Console.WriteLine("Math.Sinh(Double.NaN) = "
+ Math.Sinh(Double.NaN));
Console.WriteLine("Math.Sinh(Double.NegativeInfinity) = "
+ Math.Sinh(Double.NegativeInfinity));
Console.WriteLine("Math.Sinh(Double.PositiveInfinity) = "
+ Math.Sinh(Double.PositiveInfinity));
}
}
```

The output of the above code will be:

```Math.Sinh(-2) = -3.62686040784702
Math.Sinh(-1) = -1.1752011936438
Math.Sinh(0) = 0
Math.Sinh(1) = 1.1752011936438
Math.Sinh(2) = 3.62686040784702
Math.Sinh(Double.NaN) = NaN
Math.Sinh(Double.NegativeInfinity) = -Infinity
Math.Sinh(Double.PositiveInfinity) = Infinity
```
