如何让我的计算器以度数而不是弧度计算

Question

我已经坚持了很长时间。 如何让我的计算器以度数而不是弧度计算。 我试过 Math.toDegrees 但它没有用。 如果您决定提供帮助，谢谢。

导入 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);
    
 }
}

Answer 1

使用Math.toRadians() ，您想将度数转换为弧度，因为数学三角函数参数应该以弧度为单位：

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);
    
 }
}

为什么你需要那个？ 编程语言将始终使用弧度进行计算。 您可以接受以度为单位的输入，然后将其转换为弧度，进行计算并将其转换回输出的度数。
