(a) Let z = f(x, y, z, t, w) and x = x(r, s), y = y(r, s), z = z(r, s), t = t(r, s) and w = w(r, s). Draw a tree diagram for the chain rule and write out the formulas for the chain rule. (b) Let z = cos(x + y + e^(2(z+t)))sin(w) and let x = r^2 , y = e^(rs) , z = s^3 , t = ln(rs^(2)) and w = sqrt(rs). Find ∂z/∂s
