critical 3x^2ln(x)

critical points

3 x^{2} ln (x)

x = \frac{1}{e}

Solution steps

3 x^{2} ln (x)

Find where

f^{'} (x)

is equal to zero or undefined

x = \frac{1}{e}, x = 0

Identify critical points not in

f (x)

domain

Domain of

3 x^{2} ln (x) : x > 0

3 x^{2} ln (x)

is not defined at

x = 0

, therefore:

x = \frac{1}{e}

e^{x^{2} + y^{2}}

f (x) = 2 cos (x) - sin (2 x)

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

f (x) = \frac{x}{1 - x} - \frac{x ^{2}}{1 + x}

\frac{1}{x}
