Really DragonSlayer, 
Thanks for helping that is very nice of you but if you want to help by providing web information could you please just copy and paste the LINK. They can read it over on the other site.
Plus, you should say what the othersite is anyway because it/they should get come credit for providing this information. 
I say this because now if a mathematician answers it will be hard for the asker to see it because your answer takes up so much room.
