Problem 2. (a) (b) of f. and w. Let f(u, v, w) be a C³ scalar valued function, and let g(r, s) = f(r + s, r − s, rs). Əg Using the chain rule, give expressions for and in terms of r, s and the partial derivatives მs Ərəs a²g as a function of the partial derivatives of f and the variables u, v Give an expression for მrმs Hint: The variables r and s should not appear in your answer to (b). Remember that mixed partial derivatives commute provided that f is sufficiently differentiable!
