What are the stationary points of
f(x,y) = e^((-x^3) +3x (-y^2))
and determine their nature.
Right, so the partial derivative holding y constant is:
((-3x^2) + 3 (-y^2))e^((-x^3) +3x (-y^2))
and holding x constant:
((-x^3) + 3x -2y)e^((-x^3) +3x (-y^2))
Is that correct?
If so, I make them equal to zero?
And then find the second partial derivative to determine the nature of the stationary points?
How the hell do I do that, im not sure im doing it right..
And apologies for the untidiness of the functions.
