Question 1

Find all points where the surface  z = xy e-(x2 + 2y2) has a horizontal tangent plane.
,  
,  ,  ,  ,  (0, 0)
,  ,  (0, 0)
,  ,  ,  
◦ The tangent plane is  never horizontal.

Question 2

Find all horizontal planes that are tangent to the surface  z = x3 - 3xy2 + 6y2 + 1.
◦ z = 1  and  z = 3
◦ z = 9
◦ z = 1
◦ z = 3
◦ z = -15
