Question

你如何找到一个值的正弦角？

谢谢！

Answer 1

这是使用的示例Math.asin()：

public class Test{ 

   public static void main(String args[]){
     double degrees = 45.0;
     double radians = Math.toRadians(degrees);

     System.out.format("The value of pi is %.4f%n", Math.PI);
     System.out.format("The arcsine of %.4f is %.4f degrees %n",
                     Math.sin(radians),
                     Math.toDegrees(Math.asin(Math.sin(radians))));


   }
}
