- Why is r(t) = ⟨ƒ(t), g(t), h(t)⟩ called a vector-valued function?arrow_forwardSuppose we know that for a function f we have Vf(x, y) = (6x, 6). Find the directional derivative of the function f at the point (-1, 3) in the direction of the vector (3, 4).

- What does it mean for the differentiability of a function if only one of the Cauchy-Reimann equations (Ux = Vy and Vx = -Uy) holds?arrow_forwardCalculate the directional derivative of g(x, y, z) = z? – xy + 4y² in the direction v = (1,–3, 2) at the point P = (2, 1,–4). Remember to use a unit vector in directional derivative computation. (Use symbolic notation and fractions where needed.)
