F4UDOA: You are turning into a true posting duffas.
When mutliple people all with degrees in math,physics,eng excetera, are all telling you the exact same thing. I would tend do belive them first, then try figure out why the document is confusing you, not try show how all these people are wrong.
Read, belive, try to understand, what we are trying to tell you. Wrather than grasping at straws trying to prove somthing that is incorect.
