    Using the chain rule of partial differentiation, to show that the differential equation              
           Au_xx + Bu_xy +  Cu_yy + Du_x + Eu_y + Fu = G        
      transforms into the differential equation             
           A' u_,aa + B'u_bb + C'u_cc + Du_a + Eu_b + Fu = G                    

       The complete problem is in the attached file.
