Thanks. It might be better if Maple have added the word "solve"
there somewhere, so it is more clear that it means.

When I tried this in Mathematica, it also could not solve it
completely, but this is the answer it returned

        Solve[ ..... ==0 , y[x] ]

where .... is similar to Maple's.  The difference is that M added
the "Solve" bit. I thought this was a little bit more user-friendly
answer than just
       
           ..... = 0
