Submitted by Nidhi, on April 24, 2021

Here, we will learn about the Acos() method of Math class. This method is used to return an angle whose cosine is the specified number measured in radians.

Syntax:

    double Math.Acos(double D);

Parameter:

• D: A double number; it must be between -1 to 1.

Return value:

It returns an angle whose cosine is the specified number measured in radians.

Program:

The source code to demonstrate the use of Acos() method of Math class is given below. The given program is compiled and executed successfully.

using System;

class Sample
{
    //Entry point of Program
    static public void Main()
    {
        double Cosine = 0.0;
        
        Cosine = Math.Acos(0.7);

        System.Console.WriteLine("Result is: "+Cosine);
    }
}

Output:

Result is: 0.795398830184144
