does it really matter? btw i meant that for f(x,y) if that wasn't clear.

how could x depend on y? aren't they both independent variables?

I understand from the equation: df = {\frac{\partial f}{\partial x}} dx + {\frac{\partial f}{\partial y}} dy that: dx \neq \partial x . I understand why df \neq \partial f (df is the change in f when the change in all the variables is infinitesimal, and \partial f is the change in...
