Solwant to solve a 2nd ving a partial differential equation with textbook solution

[Anthony The Koala]

Dear Mr Chan,
Thank you for the reply. It is a learning experience of the limitations of the Prime not being able to handle PDEs.

I tried your two-stage solution and it works.


I wanted to go deeper by breaking down the statement
desolve(diff(w, x) = (2*x - y), x, w)
and do
diff(w, x) = (2*x - y), x, w)
The display said
[diff(w,x)=2*x-y x w] [0=2*x-y x w]

I tried
b]diff(w, x) = (2*x - y))[/b]
The display said
[diff(w,x)=2*x-y] [0=2*x-y]

I know desolve solves an ode but need further idea of what the Ans within the desolve does with
[diff(w,x)=2*x-y x w] [0=2*x-y x w] ?

Other question please
Obviously there are many ways to solve a PDE including taking Laplace transforms and converting them to an ODE.
Could the two-step method used in the original question be used to solve any kind of PDE and the need to specify the initial and boundary conditions?

Thank you
