   The general-purpose procedure DSOLVE1() in the library file   
   FirstOrderODEs.mth shipped with Derive 6.10 is claimed to solve exact,   
   linear, separable, homogenous and generalized homogenous differential   
   equations, as well as equations possessing an integrating factor that   
   depends only on x or only on y. There is also a separate test for an   
   integrating factor of the form x^m*y^m.   
      
   For Bernoulli and other special ODEs (among them Clairaut) there are   
   dedicated procedures.
