How to convert Trigonometric Angles in Radians using C#?

To convert trigonometric angles in Radians, multiply by Math.PI/180. This will convert degrees to radians.

The following is the code −

Example

using System;

class Program {
   static void Main() {
      Console.WriteLine(Math.Cos(45));

      double res = Math.Cos(Math.PI * 45 / 180.0);
      Console.WriteLine(res);

   }
}

Above, we converted using the following formulae −

Math.PI * angle / 180.0
