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

for (var i=0;
i<mDegrees.length;i++){
mStr+='<tr>'

+'<td>'+Math.sin(mDegrees[i])+'</td>'

mStr+='</TABLE>'

Check this link, it appears negative values are correct values.

I found another link describing the javascript math object. Apparently, the parameter sent to the functions math.cos and math.sin are considered to be radians, not degrees. Check the link to determine how to change the value from radians to degrees.
