这是使用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))));
}
}
