Can someone help me do the question 1(b),2(b)? thx
I. (a) Use chain rule to find the partial derivatives and of z = eh , where r(u, v) = Vuv and y(u, v) (b) Express as and u only in terms of u and v and evaluate at u,v)-1, 1) 2. (a) Find the directional derivative of f(x, y, 2) y at P(2,1, 1) in the direction (b) In which direction is the directional derivative maximized? What is the steepest 3. Consider the surface xy + yz + zz-5. Find (a) the tangent plane at (1,2, 1) and (b) from P to Q(0,-3,5). rate of increase of f at P? the normal line at (1, 2,1
