   > where is your list of problems? does it include any order differrential eq?   
   e.g. complex order. May I suggest you test with MathHandbook as well? it can   
   solve some problems that other cannot solve, e.g.   
   > Internal problem ID [119]   
   >   
      
   The 11,000 problems now are just listed on the pages you see. I do not   
   have them listed in separate plain text in one file. They are in an   
   internal database. One day, I will make a list in plain text file   
   to download.   
      
   Problem ID [119] is   
      
   Book: Differential equations and linear algebra, 3rd ed., Edwards and Penney   
   Section: Section 1.6, Substitution methods and exact equations. Page 74   
      
   2*x/y(x)-3*y(x)^2/x^4+(-x^2/y(x)^2+1/y(x)^(1/2)+2*y(x)/x^3)*diff(y(x),x) = 0   
      
   This is solved by Maple.  But Mathematica did not solve it for some reason.   
      
   DSolve[2*x/y[x]-3*y[x]^2/x^4+(-x^2/y[x]^2+1/y[x]^(1/2)+2*y[x]/x^   
   )*y'[x]==0,y[x],x]
