Math.Asin() Method in C#


The Math.Asin() method in C# is used to return the angle whose sine is the specified number. The number is a double value argument.

Syntax

Following is the syntax −

public static double Asin (double val);

Above, Val is a number representing a sine. The value of Val must be greater than or equal to -1, but less than or equal to 1.

Example

Let us now see an example to implement Math.Asin() method −

using System;
public class Demo {
   public static void Main(){
      double val1 = -0.0;
      double val2 = Double.PositiveInfinity;
      double val3 = Double.NaN;
      Console.WriteLine("Return value of {0} : {1}", val1, Math.Asin(val1));
      Console.WriteLine("Return value of {0} : {1}", val2, Math.Asin(val2));
      Console.WriteLine("Return value of {0} : {1}", val2, Math.Asin(val3));
   }
}

Output

This will produce the following output −

Return value of 0 : 0
Return value of ∞ : NaN
Return value of ∞ : NaN

Example

Let us see another example to implement Math.Asin() method −

using System;
public class Demo {
   public static void Main(){
      double val1 = Double.NegativeInfinity;
      double val2 = 2;
      Console.WriteLine("Return value of {0} : {1}", val1, Math.Asin(val1));
      Console.WriteLine("Return value of {0} : {1}", val2, Math.Asin(val2));
   }
}

Output

This will produce the following output −

Return value of -∞ : NaN
Return value of 2 : NaN
