extreme f(x,y)=ln|x+e^y|-sin(5xy^2)

extreme points

f (x, y) = ln ∣ x + e^{y} ∣ - sin (5 x y^{2})

None

Solution steps

Find the critical points:

None

f (x)

has no critical points, therefore there are no extreme points

None

f (x) = 3 x e^{x}

x^{4} - 8 x^{2} + 3

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

f (x) = 4 - x^{2}

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

What is the extreme f(x,y)=ln|x+e^y|-sin(5xy^2) ?
The extreme f(x,y)=ln|x+e^y|-sin(5xy^2) is None
