Here, we will find the angle for the specified cosine value and print the angle values for different cosine values.

Program/Source Code:

The source code to find the angle for specified cosine value is given below. The given program is compiled and executed successfully.

```'VB.Net program to find the angle for
'specified cosine value.

Module Module1

Sub Main()
Dim angle As Double= 0

angle = Math.Acos(2)
Console.WriteLine("Angle of specified cosine value is: {0}", angle)

angle = Math.Acos(0.3584)
Console.WriteLine("Angle of specified cosine value is: {0}", angle)

angle = Math.Acos(0.0)
Console.WriteLine("Angle of specified cosine value is: {0}", angle)
End Sub

End Module
```

Output:

```Angle of specified cosine value is: NaN
Angle of specified cosine value is: 1.20424285296577
Angle of specified cosine value is: 1.5707963267949
Press any key to continue . . .
```

Explanation:

In the above program, we created a module Module1 that contains the Main() method. In the Main() method we created a variable angle initialized with 0.

```angle = Math.Acos(2)
Console.WriteLine("Angle of specified cosine value is: {0}", angle)

angle = Math.Acos(0.3584)
Console.WriteLine("Angle of specified cosine value is: {0}", angle)

angle = Math.Acos(0.0)
Console.WriteLine("Angle of specified cosine value is: {0}", angle)
```

In the above code, we find the angle against the specified cosine values and then printed them on the console screen.
