Question
Let be a function that allows continuous second partial derivatives, we know that:
Vf(x, y) = (16x³ - xy²,4y³ - x²y - 24y² + 36y)
fxx = 48x² - y²
fyy = 12y²x² - 48y + 36y
fxy = -2xy
Consider the critic point (a,b) with positive X coordinates, that point generates a saddle point.
What's the value for a and b?
