Question 1

Is the origin a critical point of the function  f(x, y) = x2 + xy + y2? If so, classify it.
◦ yes, a local maximum
◦ yes, a saddle point
◦ yes, a local minimum
◦ no

Question 2

Find and classify the critical points of the function  f(x, y) =  x sin y.
◦ local minima at  (0, nπ)  for nonzero integers n, saddle point at  (0, 0)
◦ saddle points at all points   (0, nπ)  for integers  n
◦ only critical point is  (0, 0),  a saddle point
◦ local maxima at  (0, nπ)  for even integers  n,  local minimum at  (0, nπ)  for odd  integers  n
◦ local minima at  (0, nπ)  for even integers  n,  local maximum at  (0, nπ)  for odd  integers  n
