Re: "Leibnitz" from for partial differentiation?


Hi,

The partial derivative is

\!\(\[PartialD]\_x u[x, t]\)

in input, but Mathematica will always use 
Derivative[1,0][u][x,t]

for it until you redifine the standard output.

The total derivative is always expressed by 
partial

derivatives.

Regards
