Question : 201) Find the direction in which the function increasing most : 1757201

201) Find the direction in which the function is increasing most rapidly at the point P0.

f(x, y) = xey - ln(x), P0(-3, 0)

202) Find the direction in which the function is increasing most rapidly at the point P0.

f(x, y, z) = xy - ln(z), P0(1, -2, 2)

203) Find the direction in which the function is increasing most rapidly at the point P0.

f(x, y, z) = x y2 + z2, P0(1, 1, 2)
