Stationary points of f x y

WebIf f'' ( x) < 0, the stationary point at x is concave down; a maximal extremum. If f'' ( x) > 0, the stationary point at x is concave up; a minimal extremum. If f'' ( x) = 0, the nature of the stationary point must be determined by way of other means, often by noting a sign change around that point. WebJan 22, 2024 · The stationary point of is (1,0).
