How do I define my return value in a while table?

[CBernard]

IMPORTANT: This is a homework assignment, so I am not looking for someone to write my code, just looking for guidance on structure.

My JavaScript table generates exactly as I want, but my code is missing the return value and is therefore giving me an undefined comment in addition to the table. I have tried nesting it all within another function, which I assign to the return value, but no change.

function Trig()	{	
	
	var d, x, decSin, decCos;
	d = 0;  // radians

	while (d <= 360) 
	{
		x = Math.PI/180*(d);

		decSin = Math.sin(x);
		decCos = Math.cos(x); //

		document.write("<tr><td>" + d + "</td><td>" + decSin + "</td><td>" + decCos + "</td></tr>");

		d = d+15;
	}	
}

Got it

I added before the function closing bracket:

d='';
return d;
