WebFeb 17, 2024 · Let us find the first partial derivatives: ∂f ∂x = 6x2 + y2 +10x ∂f ∂y = 2xy +2y So our critical equations are: 6x2 + y2 +10x = 0 2xy + 2y = 0 From the second equation we have: 2y(x + 1) = 0 ⇒ x = −1,y = 0 Subs x = − 1 into the First equation and we get: 6 + y2 −10 = 0 ⇒ y2 = 4 ⇒ y = ± 2 Subs y = 0 into the First equation and we get: Webf(x,y) = 3x 2y +y3 −3x2 −3y +2. Solution: The first order partial derivatives are f x = 6xy −6x, f y = 3x2 +3y2 −6y. So to find the critical points we need to solve the equations f x = 0 and f y = 0. f x = 0 implies x = 0 or y = 1 and when x = 0, f y = 0 implies y = 0 or y = 2; when y = 1, f y = 0 implies x2 = 1 or x = ±1.
