How do you bend a four point saddle - First, we will find our first-order and second-order partial derivatives. First Partials: f x = y 2 – 12 x and f y = 2 x y − 6 y. Second Partials: f x x = – 12 and f y y = 2 x – 6 and f x y = f y x = 2 y. Next, we will find our critical or stationary points by setting our first-order partials equal to zero.
