I will give it a thumbs up if it is correctly done. Thank you..

Question 1 Use the chain rule to find out the following derivatives. (1) If w = xey/z and x = th, y = 1 - t, z =1 + 2t, compute dw (2) If z = sin r and r = st, 0 = $2 + +2, compute as a oz and oz at . (3) Suppose f is a differentiable function of a and y, and p(t) = f(g(t), h(t) ), g(2) = 4, g' (2) = -3, h(2) = 5, h'(2) = 6, fx(4, 5) = 2, fy (4, 5) = 8. Find p'(2)
