6. Suppose that the temperature T at point (x, y,z) is given by the function T = 2x2 – y? + 4z², and that a tiny heat-loving bug, currently hovering at point (1, –2,1), wants to fly in the direction in which the temperature is increasing most rapidly. Find a vector pointing in the direction he should fly.
