Hi, If I compute partial derivative of f(x, x) w.r.t. x in Sage then I get ----- sage: f(x, x).diff(x) D[0](f)(x, x) + D[1](f)(x, x) -----
Now if I say "f(x, x) = x" then from the output above I would get "2". On the other hand, had I computed it directly, I would get "1" ------ sage: (x).diff(x) 1 ------ I encountered this issue while testing out new "diff" derivative implementation. So it would be good to know the right approach for handling this issue.
