I have been trying to get this to turn out right but I keep getting some negative numbers, I think I may have done something wrong and would like to know from some of you if you see any problems. Thanks

var mStr = '<TABLE border="1" cellpadding="3" cellspacing="3">'
+'<tr><td>Degrees</td><td>Sine</td><td>Cosine</td></tr>'
for (var i=0;
i<mDegrees.length;i++){
mStr+='<tr>'
+'<td>'+mDegrees[i]+'</td>'
+'<td>'+Math.sin(mDegrees[i])+'</td>'
+'<td>'+Math.cos(mDegrees[i])+'</td>'
+'</tr>'
}
mStr+='</TABLE>'
document.write(mStr)

You want to use degrees, and the Math function uses radians

You need to convert it

Multiply degrees by PI/180

How do I set that up if you have a quick second. I appreciate the quick feedback

I see you posted this on other forums....lol
