Question 1. Let z= f(x,y), x = g (s, t). and ' y = h (s, t). with f, g & h all differentiable. (a) Set up an appropriate tree diagram for the of chain rule as done in this module's Use video lessons: (b). Use the table of values below to find Z5 (1,0) and Z (1,0). Show the set up in detail; then Simplify it numerically. g (1,0)|h(1,0) | 9, (1,0) | hs (1,0) | 9, (1,0)|h (1,0] {x (2,3)/fy (2,3) 2 3 -2 5 ST 6 4 | fx -1 10
