Hi I have this calculus question question which has caused me some trouble: Where f is diffentiable I need to show that How do I show that? Is it by using the chain rule ? /Fred

Yes, use the chain rule. For example, partial d/dx of f(x^2-y^2) is f'(x^2-y^2) times partial d/dx of (x^2 - y^2). Here f' denotes the derivative of f as a function of a single variable.
