How to use acos() function to get the arc cosine value of N in C#

Answer 1

using System;

namespace ConsoleApplication_C_Sharp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Math.Acos(0) = {0}", Math.Acos(0));
            Console.WriteLine("Math.Acos(-1) = {0}", Math.Acos(-1));
            Console.WriteLine("Math.Acos(1) = {0}", Math.Acos(1));
            Console.WriteLine("Math.Acos(0.5) = {0}", Math.Acos(0.5));
        }
    }
}


/*
run:

Math.Acos(0) = 1.5707963267949
Math.Acos(-1) = 3.14159265358979
Math.Acos(1) = 0
Math.Acos(0.5) = 1.0471975511966
