extreme f(x,y)=arcsec(x^2-|y|)

extreme points

f (x, y) = arcsec (x^{2} - ∣ y ∣)

None

Solution steps

Find the critical points:

None

f (x)

has no critical points, therefore there are no extreme points

None

f (x) = x^{\frac{2}{5}}

f (x) = 2 x^{2} - 4 x y + 3 y^{2} - 8 x + 8 y - 1 = 0

f (x) = x^{3} + 3 y^{3} + 3 x^{2} + 3 y^{2} + 24

f (x) = \frac{2 x ^{3}}{3} + \frac{3 x ^{2}}{2} - 2 x

f (x) = 9.71 x^{2} + 61.579 x + 943.59
