WebThus, the second partial derivative test indicates that f ( x, y) has saddle points at (0, −1) and (1, −1) and has a local maximum at since . At the remaining critical point (0, 0) the second derivative test is insufficient, and one must use higher order tests or other tools to determine the behavior of the function at this point. WebLet f(x,y) be a function of two variables. The partial derivative ∂f/∂xis the function obtained by differentiatingfwith respect to x, regarding yas a constant. Similarly, ∂f/∂yis obtained by …
