\newcommand{\pd}[3]{ \frac{ \partial^{#3}{#1} }{ \partial {#2}^{#3} } }

\pd{\Psi}{y}{}

+ \pd{\Psi}{x}{2} + \pd{\Psi}{y}{2}=0

[/tex]

Is this possible? I have been able to use the PDE toolbox for other simpler PDEs, for example Laplace's Equation with the same boundary conditions I am using for the above equation. But I can't seem to get it to work once I add first partial of Psi w.r.t y

Does anyone know how I can do this?

Thanks.
