This was a trial post to see if the equations would come up like they do for everyone else... but "No" it doesnt work out.
I have no idea where all that "colour" came from as i just copied 11rdc11's formula. You gents have been great help. I better do some homework on the Latex stuff before i go off and embarrass myself again.
I have to admit, this forum stuff is pretty cool. I'm a first time user and the help provided is sensation.... I shall be back!
