However (23) holds if all the partial derivatives of f up to second order are continuous. This condition is usually satisfied in applications and in particular in all the examples considered in this course. The following alternative notation for partial derivatives is often convenient and more econom-ical. f x = ∂f ∂x f y = ∂f ∂y f xx =0. If f: X → Y f: X → Y is a function and U U and V V are subsets of X X, then f(U ∩ V) = f(U) ∩ f(V) f ( U ∩ V) = f ( U) ∩ f ( V). I am a little lost on this proof.
