1 Answer Bill K I'm assuming you are thinking of this as being a function of two independent variables x and y z = tan−1( y x) The answers are ∂z ∂x = − y x2 y2 and ∂z ∂y = x x2 y2 Both of these facts can be derived with the Chain Rule, the Power Rule, and the fact that y x = yx−1 as followsSince 0 = u xy u x = (u y u) x, we can integrate at once with respect to xto obtain u yu= f(y)This is a rst order linear \ODE" in the variable y Introducing the integrating factor = exp R 1dy = ey, it becomes @y (e yu) = ef(y) Integrating with respect to ythis time yields Explanation We will be differentiating implicitly On the left hand side, we will use the chain rule in regards to the inverse tangent function d dx (arctan(u)) = u' 1 u2 Also, note that the product rule will be used for d dx (x2y) and, eventually, d dx (xy) Differentiating gives
