\nabla f (x, y)

is equal to zero or undefined

(1, 3)

Popular Examples

critical 2x^2-8x+9 critical points

2 x^{2} - 8 x + 9

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

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

critical f(x)=x^5-5x^3 critical points

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

critical f(x)=((x^2-4))/(x-1)critical points

f (x) = \frac{( x ^{2} - 4 )}{x - 1}

critical f(x)=-x^2+2x+2 critical points

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