public class HelloWorld{

 public static void main(String []args){
     Double d = 1.0;
     for(int i=1;i<90;i+=2) {
         d = d* Math.sin((double)(i*Math.PI/180));
     }
     d = 1/d;
     d =  Math.log(d) / Math.log(2);
    System.out.println("answer = "+d);
 }

}

The answer should be 44.5. Please review your code.
