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

critical points

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

(0, 0)

Solution steps

(x^{2} - y^{2}) (x^{2} + y^{2})

Find where

\nabla f (x, y)

is equal to zero or undefined

(0, 0)

\frac{300}{1 + 9 e ^{- 0.4 t}}

2 sec (x) + tan (x)

f (x) = x^{\frac{6}{7}} - x^{\frac{13}{7}}

f (x) = x^{3} - 12 x + 10

f (x) = cos^{2} (x) - sin (x)

What is the critical f(x)=(x^2-y^2)(x^2+y^2) ?
The critical f(x)=(x^2-y^2)(x^2+y^2) is (0,0)
