Consider the surface F(x, y, 2) = 2523 + sin (y823) + 2 - 0. Find the following partial derivatives dy Let W(s, t) - F(u(s, t), u(s, t)) where u(1, 0) - 2, us(1, 0) - 2, we(1, 0) = 5 w(1, 0) = -3, us(1, 0) - -7, v.(1, 0) - -6 Fu(2, -3) = -3, Fu(2, -3) = - 5 Ws (1, 0) - W.(1,0) - Note: You can earn partial credit on this problem. Use the chain rule to find of and of, where z = e" tan(y), = = 4s + 3t, y= 2s 7t First the pieces: Us dy And putting it all together. oz _ oz dz z Ju and =
