How do I make my calculator this to calculate in degrees rather than radians-CodePudding

I have been stuck on this for a very long bit of time. How do I make my calculator calculate in degrees rather than radians. I tried Math.toDegrees but it did not work. Thank you if you decide to help.

import java.util.Scanner;

public class Main {

 public static void main(String[] args) {
     
  Scanner scanner = new Scanner(System.in);
  

  // END USER INPUT VALUE IN DEGREES
  System.out.println("Please input a value to recieve the Trigonemetric value in degrees ");

  double degrees = scanner.nextDouble();
  
  double sineOfAngle = Math.sin(degrees); 
  double cosOfAngle = Math.cos(degrees); 
  double tanOfAngle = Math.tan(degrees);

  System.out.println();
  System.out.println("The Sine of "   degrees   " degrees is : "
      sineOfAngle);
  System.out.println("The Cosine of "   degrees   " degrees is : "
      cosOfAngle);
  System.out.println("The Tangent of "   degrees   " degrees is : "
      tanOfAngle);
    
 }
}

CodePudding user response：

use Math.toRadians(), You want to convert the degrees to radians because the Math trigonometric functions parameters should be in radians:

public class Main {

 public static void main(String[] args) {
     
  Scanner scanner = new Scanner(System.in);
  

  // END USER INPUT VALUE IN DEGREES
  System.out.println("Please input a value to recieve the Trigonemetric value in degrees ");

  double degrees = scanner.nextDouble();
  
  double sineOfAngle = Math.sin(Math.toRadians(degrees)); 
  double cosOfAngle = Math.cos(Math.toRadians(degrees)); 
  double tanOfAngle = Math.tan(Math.toRadians(degrees));

  System.out.println();
  System.out.println("The Sine of "   degrees   " degrees is : "
      sineOfAngle);
  System.out.println("The Cosine of "   degrees   " degrees is : "
      cosOfAngle);
  System.out.println("The Tangent of "   degrees   " degrees is : "
      tanOfAngle);
    
 }
}

Why you need that? Programming language will always use radians for calculation. You can accept input in degrees, then convert it to radians, make calculation and convert it back to degrees on output.
