What is Math.Asin() in C#?

C# has a built-in Math class that provides useful mathematical functions and operations. The Math class has the Asin() function, which is used to compute the angle whose sine comes out to be a specified number. This is also known as the inverse sine of a specified number.

Syntax

public static double Asin (double value);

Parameters

  • value: value is of the Double type and represents the input value, which is determined by finding Asin(). Its range must be:

    • -1 <= value <= 1

Return value

  • Double: Asin() returns an angle Θ measured in radians, and of type Double, whose sine is value.

    • -π/2 <= Θ <= π/2 (radians)

    It is true only for a valid range of value.

  • NaN: Asin() returns NaN type for an invalid range of value.

Radians can be converted into degrees by multiplying radians by 180/Math.PI.

Example

using System;
class Educative
{
    static void Main()
    {
        Double result = Math.Asin(0);
        System.Console.WriteLine("Asin(0) = "+ result + " radians");
        Double result1 = Math.Asin(1);
        System.Console.WriteLine("Asin(1) = "+ result1 + " radians");
        Double result2 = Math.Asin(-1);
        System.Console.WriteLine("Asin(-1) = "+ result2 + " radians");
        Double result3 = Math.Asin(2);
        System.Console.WriteLine("Asin(2) = "+ result3);
    }
}
