Given f(x, y, z) where x = u(r, s, t) . y = v(r, s, t) and z = w(r, s, t) At (r, s, t) = (0, 1, 2) we know that fa = 1. fy - 1, fz = 2. x, = -1, yr = 2 and 27 = 3. Find fr when r = 0, s = 1 and t = 2 Hint: You are not given enough information to write down the involved Jacobians completely, but enough to compute the column that you need. O2 09 None of these
