Hi, I've solved the following PDE by treating it as an ODE: $\displaystyle u_{yy} + 10u_{y} + 25u = e^{-5y}$ My solution is $\displaystyle u(x, y) = (A + By + 0.5y^2)e^{-5y}$ Have I treated the constants correctly? Thanks.

Should all of my constants be arbitrary functions of $\displaystyle x$?
Bump :)

Thanks.
