Parts (a)-(d) are distinct from each other. (a) Let F(x,y,z)=x2y+xeyz. Find the equation of the tangent plane to the level surface F(x,y,z)=0 at the point P(?1,1,0), and express it in th form ax+by+cz+d=0. (b) Find ?s?z? where z=x3+3xy2+y2,x=rs?, and y=x1?. (c) Find the directional derivative of the function f(x,y)=x3+3xy2+y2 at the point P(?1,1,?3) in the direction of the vector 41+3j. (d) Use the method of Lagrange multipliers to find the maximum and minimum values of the function f(x,y)=3x+y subject to the constraint x2+y2=10.
