please answer each part in steps

Use the chain rule to find # and " . where - c' tan(v), z = s + 36, y= 7s 3t First the pieces: And putting it all together: Let w=-ry+ yz - 3xz, r = at, y =e", = = ta Compute Ow -(-2, -2)- ( 2, 2) - Let W(s, t) = F(u(s, t), v(s, t)) where u(1,0) - 2, u,(1, 0) - 7, us(1, 0) - 7 (1,0) - -7, w,(1,0) - 2, ,(1,0) = -7 F.(2, -7) = 8, F.(2, 7) 8 W.(1,0) = W.(1,0)
