Please help me to solve problem 27
In Exercises 25-28, a function w =
point P are given.
F(x, y, z), a vector v and a
(a) Find VF(x, y, z).
(b) Find D F at P, where u is the unit vector in the direction
of v.
25. F(x, y, z) = 3x²z³ + 4xy – 3z, v = (1, 1, 1), P = (3, 2, 1)
26. F(x, y, z) = sin(x) cos(y)e', v = (2, 2, 1), P = (0, 0, 0)
27. F(x, y, z) = x'y² – y°z?, v = (-1,7, 3), P = (1,0, – 1)
