extreme xy

Solution

extreme points

x y

Solution

Saddle (0, 0)

Solution steps

Find the critical points:

(0, 0)

\frac{\partial ^{2} f}{\partial x ^{2}} = 0

D (x, y) = - 1

Check the sign of at each critical point

Check critical point

(0, 0) :

Saddle

Saddle (0, 0)

Popular Examples

extreme f(x)=2xy extreme points

f (x) = 2 x y

extreme f extreme points

f

extreme f(x,y)=-2x^3-2y^3+6xy+10 extreme points

f (x, y) = - 2 x^{3} - 2 y^{3} + 6 x y + 10

extreme f(x)=x^{1/3}+1 extreme points

f (x) = x^{\frac{1}{3}} + 1

extreme f(x)=12x-x^3 extreme points

f (x) = 12 x - x^{3}
