    Re: Help me to more steps..

    Is "D" just the unknown function? If so what do D' and D'' mean? The derivative, I presume, but with respect to what variable? If only with respect to one of x and y, this is not a partial differential equation, just an ordinary differential equation with an additional parameter. You seem to be trying to do the problem as if it were a linear equation with constant coefficient but if D is the unknown function, this is NOT a linear equation. Please explain.

    I've never seen anyone use this approach to solve partial differential equations. Where did you first learn of this?
