In the BasicTypsetting pallete , under Operators, there is the 'x'
symbol (small 'x', 2nd 'x' in the row ) which is defined as Cross...and
also, there is CenterDot next to it which is not defined at all...
First, I wonder why the small 'x' is pre-defined as Cross whereas
CenterDot is not pre-defined as Dot?.....I would have assumed that
neither be defined or both be defined...
2nd....the Documentation shows how to define CenterDot as Dot , etc...so
no problem there....however, if I combine Del from the Pallette with
either the small 'x' or the CenterDot, e.g.
Del CenterDot f_:=Div[f], .....then I get an error message that Del
cannot be followed by CenterDot f_..........
and the same if I define.....
Del 'x' f_:=Curl[f]
Is there a way to do these??...
thank you....Jerry Blimbaum
