(ii) Let variables x, y and z be linked by the two relationships f(x, y, z) = x³y - z - 1 = 0, g(x, y, z) = x + y² +2³-6=0. Derive conditions on the differentials dx, dy, and dz if the functions f and g are kept at these values. Show that (x, y, z) = (1, 2, 1) is a solution. Use calculus (i.e., by using the expressions for dx, dy, dz) to estimate the corresponding values of x and y when z = 1.1.
