how to salve this differential?

 I would think it is better form, and more self-documenting,
 to write:

 depends(y,x);
 diff(y,x)=....

 Here, Maxima will nounify diff in the second line because 
 you have told it on the first that y is a function of x.
 If you just write

 'diff(y,x)=....

  the ' will likely be a bit mysterious later when you look at
  the code.

  That's my 2p, anyway,
