IPhone : Convert java code to Objective c

I have couple of line of code in .java file, What i want to do is i want to convert that lines of code to objective c lines..

Here are the lines:

(1)

return 9.87*Math.sin(Math.toRadians(2.0 * B)) - 7.53*Math.cos(Math.toRadians(B)) - 1.5*Math.sin(Math.toRadians(B));

(2)

    Calendar today = Calendar.getInstance();
    Calendar now = Calendar.getInstance();
    now.set(Calendar.DAY_OF_MONTH, 1);
    now.set(Calendar.MONTH, 0);
    now.set(Calendar.YEAR, today.get(Calendar.YEAR));
    (today.getTimeInMillis() - now.getTimeInMillis())/(1000*60*60*24.0) + 1;

is there any online tool that convert this code to objective c codes ? or can you please help me to convert.

Thank you for reading and thanks in advance
