critical f(x,y)=x^2+2xy-y^2+y+1

critical points

f (x, y) = x^{2} + 2 x y - y^{2} + y + 1

(- \frac{1}{4}, \frac{1}{4})

Solution steps

x^{2} + 2 x y - y^{2} + y + 1

Find where

\nabla f (x, y)

is equal to zero or undefined

(- \frac{1}{4}, \frac{1}{4})

f (x) = \frac{1}{x} + ln (x)

f (x, y) = - x^{2} - y^{2} - 2 y + 5

y = (x + 2) e^{1 - x}

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

x^{3} - x^{2}

What is the critical f(x,y)=x^2+2xy-y^2+y+1 ?
The critical f(x,y)=x^2+2xy-y^2+y+1 is (-1/4 , 1/4)
