critical f(x,y)=x^3-2y^2-2y^4+3x^2y

critical points

f (x, y) = x^{3} - 2 y^{2} - 2 y^{4} + 3 x^{2} y

(- 1, \frac{1}{2}), (- 2, 1)

Solution steps

x^{3} - 2 y^{2} - 2 y^{4} + 3 x^{2} y

Find where

\nabla f (x, y)

is equal to zero or undefined

(- 1, \frac{1}{2}), (- 2, 1)

f (x) = x^{2} (x - 12)^{2}

f (x) = sin^{2} (6 x) + cos (6 x)

f (x) = x^{5} - 5 x + 3

f (x) = 6 x^{3} - 2 x

f (x) = sin (2 x) - 2 cos (x)
