C# - Math Asin() Method
The C# Math Asin() method returns arc sine of a value. The return value will be in the range -𝜋/2 through 𝜋/2. In special cases it returns the following:
- If the argument is NaN or its absolute value is greater than 1, the method returns NaN.
Note: Asin() is the inverse of sin().
Syntax
public static double Asin(double arg);
Parameters
arg |
Specify the value. |
Return Value
Returns the arc sine of the value.
Example:
In the example below, Asin() method is used to find out the arc sine of a given value.
using System;
class MyProgram {
static void Main(string[] args) {
Console.WriteLine(Math.Asin(0.5));
Console.WriteLine(Math.Asin(1));
Console.WriteLine(Math.Asin(2));
}
}
The output of the above code will be:
0.523598775598299 1.5707963267949 NaN
