Question Number 182003 by MWSuSon last updated on 03/Dec/22
u_(xx) −u_x u_y −u_(yy) +2u_y −2u_x =e^(2x+3y) +sin(2x+y)+xy
$$\mathrm{u}_{\mathrm{xx}} −\mathrm{u}_{\mathrm{x}} \mathrm{u}_{\mathrm{y}} −\mathrm{u}_{\mathrm{yy}} +\mathrm{2u}_{\mathrm{y}} −\mathrm{2u}_{\mathrm{x}} =\mathrm{e}^{\mathrm{2x}+\mathrm{3y}} +\mathrm{sin}\left(\mathrm{2x}+\mathrm{y}\right)+\mathrm{xy} \\ $$
