1. Equation for Tangent Plane: Write the equation for the tangent plane for the surface S at the point P. Remember we have two different formulas for the tangent plane to a surface, one for graphs; one for level sets. (a) 3:2: =y2m3sc3y; P: (1,2) (b) S:1=z32$y+333; Q=(_113171/3) 2. Consider the surface dened by f (:13, y) = 6\"\"23'92. Find the point in the region .132 + 9y2 3 1 and the direction that maximizes the rate of increase of f
