Prove the following identities, assuming that all derivatives involved exist and are continuous.
Consider the following function which is defined for all x and y:
f(x, y) = 2(1-p²)x²y² - x² - y² + 3pxy + 2x+4y+2
where p is a constant.
(a) Find the first order derivatives of f and enter them as functions of x, y and p
(b) Find the second order derivatives of f and enter them as functions of x, y and p
(c) For p = 1, find the stationary point (x*, y*).
Find the directional derivative of f(x, y, z) = xy + z³ at the point P = (3, −4, −3) in the direction pointing to the origin.
