But, you have to admit that you've been fairly condescending and somewhat insulting toward us in a number of posts before and suggesting we didn't understand the math you were cutting and pasting. That's called "proof by intimidation." And so, well, some of us do understand some math. Maybe not on the level that mechanical engineers and architects understand and use every day. Don't take it so hard Pants.
I actually think I have been quite polite. I have even tried to avoid posting things that could be interpreted as insulting. Obviously, i was not entirely successful.
