A person is running over a mountainous terrain, the equation of the surface of the terrain is given by f = sin(2x)+3 cos (6лy). The runner is travelling at a velocity of 3t² in the x-direction and 2t in the y-direction, where t denotes the time elapsed. Find the rate of change of f with respect to t at the instant t = 4. Assume that at t = 0, both x and y are 0.
